Overview of Cement Anti-crack Agent

Cement anti-crack agent is Tongrun's full use of the physical and chemical changes in the cement curing process. The chemically synthesized powder can prevent cracking and cracking from both physical and chemical aspects, which can significantly improve the strength of lightweight concrete.

The anti-cracking agent can effectively solve the problem of the natural cracking of cement products. Adding the anti-cracking agent to lightweight concrete can reduce the cracks and hollowing of lightweight concrete, increase the strength of mortar and improve the quality of the project.

The anti-crack agent solves the problems of large shrinkage deformation, poor impermeability, and weak crack resistance of ordinary cement products. Directly incorporated into cement can effectively control the plastic shrinkage and cracks caused by the segregation of lightweight concrete, significantly improving the strength of lightweight concrete cracking performance, anti-freezing and anti-shock performance and, wear resistance and earthquake resistance.

Characteristic of Cement Anti-crack Agent

1) Crack resistance: The crack resistance agent is easily dispersed in lightweight concrete to form a three-dimensional space structure, which effectively improves the phenomenon of reduced hardening and cracking caused by too fast drying of mortar and insufficient moisture;

2) Low shrinkage: The mixture will not shrink and settle, and the anti-crack agent can absorb internal stress and improve crack resistance;

3) Operability: Anti-crack agent can increase the plasticity of mortar, improve construction operability and work efficiency;

4) Anti-slip property: Because the anti-crack agent has a thickening effect, it can prevent or avoid the slippage of mortar and adherend during construction to a certain extent.

How does cement anti-cracking agent work?


The working principle of cement anti-cracking agents mainly involves the improvement of the microstructure and properties of concrete. Some anti-cracking agents introduce polymer materials to form a "microfiber" network in concrete to enhance the toughness and tensile strength of concrete. In addition, some anti-cracking agents can react with cement hydration products to produce more stable hydration products, thereby reducing shrinkage and cracking of concrete.


What occasions are cement anti-cracking agents suitable for?


Cement anti-cracking agent is suitable for various occasions where the anti-cracking performance of concrete needs to be improved, such as bridges, roads, tunnels, high-rise buildings, etc. The use of anti-cracking agents is especially important in dry or humid environments, large-volume concrete construction, and concrete structures that require long-term exposure to the external environment.


What types of cement anti-cracking agents are there?


Cement anti-cracking agents are classified in many ways. According to its mechanism of action, it can be divided into anti-crack agents that reduce the shrinkage of concrete and anti-crack agents that increase the toughness of concrete; according to its components, it can be divided into inorganic anti-crack agents, organic anti-crack agents and composite anti-crack agents.


How to use cement anti-cracking agent?


When using cement anti-cracking agent, the anti-cracking agent should be mixed with cement according to the recommended ratio in the product instructions. During the mixing process, it should be ensured that the anti-cracking agent and cement are mixed evenly to avoid local excess or deficiency. After mixing is completed, the working performance of the concrete should be checked to ensure that it meets the construction requirements.


What issues should be paid attention to when using cement anti-cracking agent?


When using cement anti-cracking agents, you should pay attention to the following points: First, you should choose the type of anti-cracking agent that suits the engineering needs and environmental conditions; second, you should use and add anti-cracking agents correctly in accordance with the product instructions; in addition, you should also pay attention to the following: Compatibility of other concrete additives to avoid chemical reactions or negative interactions; at the same time, the performance of concrete should be regularly monitored and evaluated so that construction methods can be adjusted and optimized in a timely manner.


How effective are cement anti-cracking agents?


The effectiveness of cement anti-cracking agents varies depending on the specific product, but in general, the use of anti-cracking agents can significantly improve the crack resistance of concrete. Experimental data and engineering practice have proven that the rational use of anti-cracking agents can effectively reduce the risk of concrete cracking and improve the durability of the structure.
