Admixtures have compatibility issues with cement with high C3A content!

The main components of cement are C3S, C2S, C3A, and C4AF. The adsorption activity sequence of these mineralized components is generally believed to be C3A>C4AF>C3S>C2S, among which C3A has the highest adsorption capacity for water reducing agents. Therefore, when the dosage of water reducing agents is constant, the fluidity of concrete decreases with the increase …

Admixtures have compatibility issues with low alkali and sulfur deficient cement!

Adding water reducing agents to sulfur deficient cement usually results in poor fluidity, and increasing the dosage of water reducing agents may have certain effects, but it will also increase the bleeding of concrete. The prepared concrete has poor uniformity and fast slump loss, so commonly used water reducing agents are difficult to adapt to, …

Admixtures have compatibility issues with high alkali cement

The soluble alkali in cement is usually expressed as Na2O equivalent, which mainly comes from the clay and mixture used in the production of cement. An appropriate amount of soluble alkali is beneficial for promoting cement hydration and promoting the early strength development of concrete. Experiments have shown that the flowability of cement concrete increases …

Adding magnesium as an anti cracking agent can effectively control concrete cracks

Concrete is a building material made by mixing raw materials such as sand, gravel, and cement. During the hardening process, it releases a large amount of heat. Due to the poor thermal conductivity of concrete, this heat often accumulates inside the concrete, forming a large temperature difference, leading to problems such as cracks and deformation. …
