generally speaking, bitcoin and cryptocurrency tokens provide you with more control. You effectively cut the middleman between you and your money. No bank can decide how long a transaction will take and how much it will cost. You can also control where funds are stored and how they are accessed. Of course, control brings corresponding responsibilities
2. Affordability
since the middleman is not in the picture, you can save some transfer fees. Moving bitcoin from one wallet to another costs a negligible amount of money. It is cheaper for businesses to accept bitcoin payment than credit card payment
3. Speed
in addition to saving international transfer fees, you can also enjoy higher transaction speed. What does it take your bank a few days to do? Bitcoin can do it in a few minutes
4. Convenient
with bitcoin, online payment is easier and faster. If you want to donate or pay for something that will not be delivered, you do not need to disclose any personal details. Just send bitcoin to their wallet address
5. Security
it is safer for businesses to accept bitcoin than fiat money. When businesses accept credit card payments, they risk fraud and reverse payments. Bitcoin payment is irreversible, so there is no risk of reversal
6. Privacy
one of the main advantages of using bitcoin is that it provides privacy and relative anonymity. You don't need to provide any personal details to access the bitcoin wallet. All you need is a device to store it - even a piece of paper. Bitcoin transactions are only linked to your wallet address
7. Reliability
bitcoin network is essentially a point-to-point payment system. This allows you and you to remit money to anyone who participates in the party. You don't have to rely on the bank to do the work to make the transaction effective. In Ethernet, the risk of payment loss is small, which eventually makes it a more reliable way of payment
8. Investing in
bitcoin wasn't worth a lot of money ten years ago. Let's see where it has been since 2009. From a few dollars in December 2017 to nearly $20000. At the time of writing, it is now stable at around $6000. As more and more people adopt bitcoin, bitcoin will not be everywhere. Investing in it may be risky, but it's absolutely profitable.
The so-called fair faced concrete, refers to no longer use other decoration, decoration methods, will be removed after the concrete directly as the building surface. Architects often use the surface texture of concrete - rough, smooth or special surface texture and traces left by construction as the special visual effect of fair faced concrete
the water absorption rate of concrete surface is relatively high. Without any protection, the concrete will be damaged by sunlight, ultraviolet, acid rain, oil gas, oil, etc. in the natural environment, and graally lose its true colors. The concrete will be neutralized and damaged as time goes on, and its surface effect will become increasingly dirty, affecting the outlook. Therefore, the transparent protective spraying on the concrete surface can not only solve the problem of protecting the concrete and make it more rable, but also prevent pollution and keep clean, and will not darken e to water absorption. Therefore, the color of fair faced concrete buildings can remain unchanged in the rain, unlike urban overpasses, which are filthy when it rains, Therefore, it is also called dry spraying< br />
1) when the large formwork is processed and manufactured in the workshop, it should be operated on the large platform with accurate blanking size and tight seam. The height difference between the formwork panel joints is less than 1 mm, and the height difference between the formwork joints is less than 2 mm. After the formwork assembly is completed, all the joints should be polished with a polishing machine to control the height difference of the slab joints within the minimum range
2) after the large formwork is transported to the site, it shall be marked on the formwork one by one according to the design drawings, and the installation shall be guided by a specially assigned person
3) colorless light engine oil shall be used as the mold release agent, and the brushing shall be uniform without missing. The cleaning and maintenance of formwork shall be strictly controlled. The corner formwork of large formwork shall be removed after once a week, the concrete slurry in the gap shall be removed, and the angle steel shall be corrected to prevent slurry leakage caused by loose joints
4) after each concrete pouring, the concrete on the back ridge of the large formwork shall be cleaned in time, and the inclination angle shall be adjusted when landing α= nineteen ° Left and right, standing on a solid and flat ground to prevent the deformation of large formwork e to uneven ground. After the large formwork falls to the ground, the concrete impurities on the board surface shall be cleaned immediately, and then the release agent shall be applied. After the inspection is qualified, it shall be hoisted and used
5) when the large formwork is removed, the crowbar should be used to slowly pry it loose, and then lift it away, instead of hammering or forced lifting<
5 control points of mix proportion and raw materials of fair faced concrete ± 20) The slump of roof concrete is (160 ± 20) The concrete slump of shear wall above 18 floors is (200 mm) ± 20) The slump of roof concrete is (180 ± 20) Mm to rece the bleeding of concrete. At the same time, the air content of concrete should be controlled not more than 2%, and the initial setting time should be controlled between 3 h and 5 h
5.2 control points of raw materials for fair faced concrete
1) cement: slag Portland cement should be selected, the manufacturer, strength grade and batch number should be determined, and it is better to achieve the same clinker
2) coarse aggregate: the crushed stone with high strength, 5 mm-25 mm particle size, good continuous grading, mud content no more than 0.5% and no impurities shall be selected, and the place of origin, specification and color shall be determined
3) fine aggregate: coarse sand should be selected, the fineness molus should not be less than 2.6, the mud content should not be more than 2%, and there should be no impurities. It is required to determine the origin and quality
4) water: drinking water should be used for concrete mixing. When underground water is used, it should be inspected and concrete can be mixed only when it meets the standard of water for concrete mixing
5) admixture: unf23b composite retarding superplasticizer. In the proction process of fair faced concrete, it is necessary to strictly feed according to the proportion determined by the test, without any randomness, strictly control the water cement ratio and mixing time, check the moisture content of sand and gravel at any time with the climate change, and timely adjust the water consumption
6 key technologies in construction
1) structural joints are not exposed: this technology is mainly to solve the common problems of floor roof and wall joints exposed, and beam mouth and joints exposed, which affect the appearance. The specific methods are as follows:
A. when pouring wall concrete, the pouring elevation of wall concrete shall be controlled at 1.0cm higher than the roof, and after the wall formwork is removed, Pop up 50 lines on the wall and the horizontal line on the roof formwork, and the horizontal line on the roof formwork is the pouring elevation of the wall concrete. Then use the cutting machine to cut along the horizontal line on the roof formwork, remove the excess concrete, and blow away the impurities on the wall head before setting up the roof formwork. In this way, after pouring the top plate, the joint is hidden in the top plate, which can ensure the square and beautiful internal corner
B. when the beam mouth is embedded, the embedded size should be 3.0cm smaller than the actual beam mouth, and it should be made into the shape of big inside and small outside bell mouth. After the wall formwork is removed, the beam edge line and beam mouth cutting line should be ejected according to the axis, and the beam mouth cutting line is 2.0cm smaller than the actual size. Then, the cutting machine should be used to cut along the beam mouth cutting line, and the sundries in the beam mouth should be removed and the st should be blown away by air compressor, After pouring concrete, the joint will be hidden in the beam
2) no slurry hanging around the roof: the key technology to solve this common problem is to seal around the roof. During the construction, the following methods are mainly adopted: before the formwork is supported, a 5mm wide and 5mm thick sponge strip is pasted around the wall along the ink line of the formwork, which is mainly used for sealing, and then square wood is used to squeeze the sponge strip around to block the leakage channel completely
3) no grout leakage around the door and window openings: in the past shear wall construction, e to the large gap at the edge of the door and window openings, watermarks, even grout leakage and other common quality problems often appear at the edge of the openings after concrete pouring and formwork removal. In this project, the shaped door and window formwork is specially designed with accurate size, large rigidity, and more tight connection with the large formwork. During the construction, a 5mm thick sponge strip is pasted on the frame of the door and window formwork to make the connection between the large formwork and the door and window more close, and there is no slurry leakage and watermark phenomenon after the formwork is removed
4) there is no leakage or rot at the root of shear wall
A. ring the pouring of the roof, the concrete surface must be rubbed and polished with a trowel within 10cm on both sides of the wall [1]
B. when pouring the wall concrete, the mortar with the thickness of 10cm is laid first, which is the same as the cement mortar in the concrete ratio
C. when the formwork is erected, mortar shall be used to plug the joint at the root of the formwork in advance
5) control points of fair faced concrete pouring
A. implement construction technology assurance measures and strictly implement relevant regulations
B. reasonably schele the feeding time of mixer truck and measure the concrete slump one by one
C. strictly control the height of each cutting to ensure that the layer thickness does not exceed 50cm
D. the vibration method should be correct, without missing vibration or over vibration. The second vibration method should be adopted to rece the surface bubbles, that is, the first vibration should be carried out when the concrete is poured, and the second vibration should be carried out when the concrete is standing for 20-30 minutes
E. strictly control the vibration time and the depth of the vibrator inserted into the next layer of concrete to ensure that the depth is between 10 cm and 15 cm. The vibration time is generally about 15 s until the concrete slurry no longer sinks and no bubbles appear on the surface
6) control points of fair faced concrete curing. The side formwork of fair faced concrete shall be removed after 8h ~ 12h (depending on the air temperature). After the formwork is removed, the cover for surface maintenance shall not be directly covered with straw mat to avoid yellow pollution. It can be cured by spraying water (no less than 4 times a day) or covered with plastic film. The curing time shall not be less than 7 days
7) repair control points of fair faced concrete. Remove the floating slurry and loose sand on the surface immediately after removing the formwork, use the cement of the same variety and strength grade to make the cement slurry, repair and embed the defective parts. After the cement slurry is hardened, use sandpaper to polish the surface of the whole component, and use manual grinding wheel to smooth the contact trace on the board surface, so as to ensure the smooth surface
practice has proved that fair faced concrete technology can not only create economic benefits, improve project quality and bring social benefits, but also has positive significance in promoting the quality of local construction instry and accelerating the pace of application of new technology in construction instry, which has a wide application prospect.
at this time, Lu Yu was both happy and worried. What he was happy about was that the memory regulator was genuine and made Mengmeng so close to herself. In the future, when the memory regulator is upgraded to the highest level, I will be invincible
at this time, Zhong Tao had finished ordering. Lu Yu looked straight at the Tibetan people who ate raw meat and explained in a soft voice, "don't make a fuss. It's normal to eat raw meat in Tibetan areas. Tibetan people have different food culture from Han people. Beef and mutton are their staple food. "
after President Liu came to the hospital president's office, he immediately changed his gentle look and looked at Lu Yu sternly. President Liu said, "Li Jun has told me about you and your mother all the way. Your mother lives in our hospital and doesn't pay for the medicine. Li Jun handles it according to the rules of the hospital. You want to kill Li Jun
just before taking a bath, Lu Yu made up his mind to move out of here. Living with such a cruel woman, Lu Yu was really afraid that he would lose his life even if he was confused
after seeing that the three bitdogs were soft, Xiao walked up to them very leisurely, bared his teeth and barked twice. The three fighting dogs, who had been too scared to move, drooped their heads and purred like begging for mercy.
there is an artificial lake in the drum of Tongshan. In the center of the lake, there is a stone pavilion for people who are tired of playing. But to get to the Shuixie stone pavilion, you have to take a dragon boat, which costs money
"Xiao Yu, it's cold outside. It's really not good to change clothes outside. Well, I'll wait outside for a while. There's plenty of water in the car. You can simply clean it With that, Zhang Fa jumped out of the Hummer
with the sound of memory tuner, a yellow and white line appears again, but at this time, the yellow and white line has a new change. The yellow part still occupied the majority, but the number above also changed from 8.3 to 13.3. The white part, from 2 to 6.3
hearing Lu Yu's words, Lu Ning said timidly, "no, it's just that it's very expensive here."
at this moment, Lu Yu believed what Bai Qiang's mother said. She was just playing
with these words, Lu Yu jumps out of the Humvee with a gun and approaches the unknown object carefully
at this time, Lu Yu finally realized that something was wrong. When he opened his eyes, he saw a kidnapper running in in a panic and said to Yazi, "boss, hurry up, we can't stand it."
If it is to make fair faced concrete on the existing base surface, it can be completed in the form of imitating fair faced concrete. It can also be done in the form of fair faced concrete hanging slab. There are some differences between the two processes, one is to use fair faced concrete protective agent and special mortar putty for fair faced concrete, the other is to use precast hanging slab proced by pouring process
let's talk about the practice of imitating fair faced concrete first, using lanbao fair faced concrete paste putty combined with fair faced concrete protective agent. First of all, the base surface should be made well, and then the fair faced concrete paste putty should be made. At this time, the fair faced concrete finish effect can be imitated as cast-in-situ, but there are some places that are not satisfactory for the color. It doesn't matter, you can go on to the next step. The finished putty layer shall be polished, and then the st shall be removed to make the primer to prevent the later alkali return. After drying out, the color of fair faced concrete shall be adjusted as necessary to achieve a satisfactory effect. Finally, the finish coat shall be made. This process is also a common proction process of fair faced concrete wall. The effect is very good, environmental protection, no cracking and no peeling, There will be no problem in ten to fifteen years. Now there have been cases for more than ten years
