What role does calcium stearate play in concrete？

Calcium stearate, also known as hexadecyl calcium stearate, is a commonly used concrete additive. Its chemical structure is C16H33COOH Ca, and its appearance is white powder or particles. Calcium stearate is an environmentally friendly and harmless material that can play various roles in concrete. The following is an introduction to the application and properties of calcium stearate in concrete by Sainuo.

The calcium stearate produced by Sainuo has a long cycle and good heat resistance; Simultaneously, it has no sulfur pollution; Good lubrication and demolding properties; Good stability; Has a certain degree of dispersibility.

The application of calcium stearate in concrete

1. Improving the crack resistance performance of concrete

The addition of calcium stearate can increase the cohesion and surface tension of concrete, effectively improving its crack resistance performance. It can increase the early strength and specific flexural strength of concrete, reduce the shrinkage and expansion rate of concrete, stabilize the volume of concrete, and reduce concrete cracking.

2. Improving the durability of concrete

The addition of calcium stearate to concrete can improve its durability. It can reduce the permeability and porosity of concrete, and prevent water erosion and carbon dioxide erosion. These measures help to extend the service life of concrete and improve its durability.

3. Reduce the amount of cement used

The addition of calcium stearate can also reduce the amount of cement used. It can improve the flowability and durability of concrete, thereby reducing the amount of cement used in concrete. This not only reduces production costs, but also benefits the environment.

Calcium stearate is an additive commonly used in concrete. It can improve the crack resistance and durability of concrete, while also improving its durability and reducing the amount of cement used. Its addition can improve the flowability and durability of concrete, and also contribute to environmental protection.
