Concrete admixture BTC made in Guangdong

1. We've got people pushing potent drugs. It can save cement and cost

in my opinion, there are quite a lot of advertisements in the instry. It was also in an instry meeting. The video they played was a little interesting. I left a business card. Unexpectedly, I sent two bottles of samples to me and tried them. It was not bad. It saved 20kg of cement. The strength in 7 days was almost the same as the benchmark, but the later strength soon caught up with it, which was 3-4mpa higher. It has good workability, and the data of slump loss are ideal

I've also tried CTF's procts. If the effect does not last forever, the most hateful thing is that the quotation is confusing. If you don't bargain with them, they will certainly pit you
BTC seems to be a functional additive. Now its main business has been transferred to water recer. I don't know the effect of the proct. We haven't heard of anyone selling it here.

2. The necessary admixture for commercial concrete is pumping agent. It is a compound additive, including water recing, retarding, air entraining and other functions. In addition, admixtures that may be used include early strength agent, antifreeze agent, expansion agent, waterproof agent, shrinkage recing agent, etc. In addition to the large amount of pumping agent, water recer, retarder or air entraining agent can also be used separately according to the needs of the project.

3. I haven't heard of this platform. Since it's a platform, you can find the customer service of the platform to help handle it. If there is no customer service at all, or you can't solve it, you may have to take a cut and gain wisdom.

4. The liquid admixtures in the commercial concrete station are pumped into the metering scale of the mixer by adding a self-priming pump between the admixture storage tank and the mixer. The measurement of the powder admixtures is more time-consuming than that of the liquid admixtures. The powder admixtures must be weighed by manual before they are put into the mixer.

5. In addition to the calculation method mentioned on the second floor above, the regulations of different provinces are also different. Some provinces have supplementary quota, which is 40 yuan or 50 yuan for 1 m3 concrete admixture.

6. The admixtures of commercial concrete station are installed with electric self-priming pump or gear pump system between the storage tank of admixtures and the pipeline connection of commercial concrete mixer. When liquid admixtures are needed, the electric pump is started to pump the admixtures into the admixtures measuring scale of concrete mixer, and then the measured admixtures flow into the measured mixing water for mixing. Powdery admixture is manually measured in advance and then poured into the measured mixed sand and stone to mix concrete.

7. There are many kinds of additives. Generally, polycarboxylate superplasticizer is commonly used in commercial concrete station, low concentration type, and the price is generally 1600-2000. It depends on the method of payment.

8.

1. Cost of raw materials: cost of cement, sand, sand, crushed stone, fly ash, mineral powder, admixture and other materials, which can be easily calculated according to mix proportion and unit price of raw materials

2. Freight: it mainly refers to the fuel consumption of various vehicles, mainly including the cost of mixer, pump truck, loading truck, etc., which can be calculated through statistics to give you a reference value. I remember that the cost of mixer (the distance from the construction site is about 20km) is 18-24 yuan / m3, and that of pump truck is 15-20 yuan / m3

3. Employees' wages: generally, the total wages of employees in commercial concrete units are still in linear relationship with the proction volume, which depends on the wage level of various places and the situation of various enterprises

4. Depreciation of equipment: the depreciation period should be considered. For example, the boss decides to recover the cost in five years, that is, the total amount of equipment / estimated output in five years, that is, the depreciation cost of equipment in each cubic meter of concrete

5. Marketing expenses: including all the expenses (catering, entertainment, kickbacks, etc.) incurred by the marketing department in the process of commercial concrete sales, which should be controlled within a certain range

6. Water, electricity and communication costs: including water, electricity and communication costs in the proction process and employees' living and working process, which are relatively fixed

Commercial concrete is the transformation of concrete proction from extensive proction to intensive large-scale proction, which realizes the specialization, commercialization and socialization of concrete proction. It is an important reform for building to rely on technological progress to change small proction mode and realize building instrialization

extended data:

because the commercial concrete mixing station is set in the edge of the city, compared with the traditional mixing process on the construction site, it reces the st, noise, sewage and other pollution, and improves the working and living environment of urban residents. With the development and expansion of commercial concrete instry, it graally plays a greater role in the treatment, disposal and comprehensive utilization of process waste and urban waste, recing environmental degradation

The mineral admixtures should be clearly marked when they are stored. Different mineral admixtures and cement should not be stacked together. They should be moisture-proof and rainproof, and should comply with the relevant environmental protection regulations; When the storage period of mineral admixtures exceeds 3 months, they should be rechecked, and only those qualified can be used

the samples of admixtures for inspection should be consistent with those purchased in large quantities, and should be marked according to different suppliers, varieties and brands, and stored separately; Powdery admixtures should be protected from moisture caking, if there is caking, it should be inspected

The qualified ones should be crushed until they pass the 600 mm sieve; Liquid admixtures should be stored in closed containers, and should be sun proof and antifreeze. In case of precipitation and other abnormal phenomena, they can only be used after passing the inspection

9. Visa did not launch virtual currency, which is a false information, a typical Ponzi scheme. But Ponzi scheme does not mean that it can not make money. There are still some people who can make money, only a few people, and most people are cheated. Can you be yourself and think about it seriously. This currency is similar to the Morgan currency, which has disappeared

the mainstream digital money market depends on people's belief in a certain kind of currency, and this kind of currency does have certain technical advantages or potential application scenarios, such as bitcoin, Ruitai coin, vitality coin, etc.
