What factors are related to the price of concrete admixtures? 90% of people don’t know!

The use of small admixtures can not only ensure the quality of construction projects, but also improve the working performance of cement products. It has become a common thing to add small materials during the replacement of concrete. However, what factors are related to the price of concrete admixtures? Different small materials have different prices. At the same time, due to various problems faced during use, it has become a trend and necessity to add small materials when synthesizing and compounding concrete. Price of concrete admixtures.jpg

According to the test report: when cement uses anhydrite as a setting agent, because the gypsum has a negative impact on sugar-calcium water-reducing agents, lignin-based water-reducing agents and multi-component water-reducing agents, Alcohol superplasticizers have strong adsorption, so they reduce the solubility of gypsum and cannot provide enough sulfate ions to react with C3A to form ettringite. It will also cause C3A to hydrate rapidly. When in cement When the C3A content is high (greater than 8%), it may cause "false setting" in concrete.

What factors are related to the price of concrete admixtures? It is related to the production process of small admixture materials. In addition, we must improve the raw material ratio design of its ratio

1. High-performance features are designed for specific application environments, and projects must be specifically tested based on their own engineering characteristics, regional climate, and environmental characteristics.

Since transportation costs greatly affect the price of floor materials, the selected floor materials should be sourced from local materials as much as possible while meeting the specifications.

2. High-performance trial fitting should not pursue high, early and strong, but should meet the design requirements, which is of great significance to the volume stability and economy of concrete.

3. High performance does not mean high fluidity. Its working performance only needs to meet the engineering characteristics and construction process requirements.

4. Sufficient mineral admixtures should be added to high performance, which can be one type or several types. On the premise of meeting the strength and construction technology, the amount of cement and water consumption should be minimized. , an appropriate water-cement ratio should be used to ensure the volume stability and economic performance of concrete.

The price of concrete admixtures is related to many factors. Therefore, we need to pay more attention to the proportion design in the synthesis process. </p
