Concrete mixing plant admixture of common misuses

Haomei inspected Guangdong area more than ready mix concrete plants, found some mixing has always been difficult to improve concrete strength. If you want to increase the strength of concrete, in the fierce market competition environment and the confused faces increased costs, lower profits. Through in-depth research, analysis, Haomei found that most such misunderstanding of concrete mixing plant into concrete admixtures used, as follows:

1. low price purchase admixture

Due to fierce competition in the market, and strict control of cement mixing plant for the procurement of raw materials. Concrete mixing plant hope with the minimum purchase prices of raw materials, concrete admixture as well.

Concrete mixing plant the additive the purchase price down, will inevitably lead to additive manufacturers to reduce the levels of quality. Concrete mixing plant admixture of procurement contracts are rarely clear acceptance criteria. Even if there is, it is clearly in accordance with the national standard and national standard is the minimum standard. This leads to additive manufacturers in the case of low bid, supply lower quality additives, usually barely reached national standards, it is difficult to meet the functional requirements of concrete mixing plant additive.

2. limit the amount of admixture

Concrete mixing plant decision-making to meet stricter than the cost, even the amount of cement, admixtures were specifically requested. This necessarily led to the technology sector in the mix design, can't break through the decision-making admixture of high volume requirements.

3. the lack of quality control and test validation on the additive.
