Cracking the Code on Cement: Anti-Crack Agents for Stronger Structures

The anti-crack agent is an organic polymer mixed lotion that makes full use of the physical and chemical change mechanism during the curing process of cement mortar and concrete. The chemical synthetic powder can prevent and resist cracks from both physical and chemical aspects and can significantly improve the strength of cement mortar and concrete.

Performance of crack inhibitor

After mixing mortar with water, the water has a high surface tension, which causes shrinkage stress on the system during early water evaporation. After adding crack-resistant agents, the material quickly disperses in the mortar and forms a three-dimensional spatial structure when mixed with water, effectively reducing the surface tension of the mortar, suppressing material shrinkage, and continuously generating calcium vanadium stone with cement, thereby improving the crack resistance and strength of the mortar.

Crack-resistant agents in mortar can effectively improve phenomena such as poor hardening and cracking caused by rapid drying of mortar and cement shrinkage. They can significantly reduce the occurrence of cracks and hollowing in mortar or concrete, increase mortar strength, and improve engineering quality. Crack-resistant agents solve the problems of large drying shrinkage deformation, poor impermeability, crack resistance, and frost resistance of cement mortar. When directly added to cement, it can effectively control the plastic shrinkage and cracking caused by the segregation of mortar, greatly improving the crack resistance, frost resistance, impact resistance, and wear and seismic resistance of mortar.

Product characteristics of crack resistance agent

Crack resistance: Crack-resistant agents are easily dispersed in mortar, forming a three-dimensional spatial structure, effectively improving phenomena such as poor hardening and cracking caused by rapid drying and insufficient moisture in the mortar.

Low shrinkage: The mixture will not undergo shrinkage settlement, and the crack resistance agent can absorb internal stress and improve crack resistance.

Operability: Crack-resistant agents can increase the plasticity of mortar, improve construction operability, and enhance work efficiency.

Adhesive properties: Due to the increased plasticity of mortar, it can better bond the substrate and the bonded material.

Slip resistance: Due to the thickening effect of crack inhibitors, they can, prevent or avoid the slip phenomenon of mortar and bonded materials during construction.

Application areas of crack inhibitors

Crack-resistant agents are widely used in civil construction, bridges, highways, runways, dams, cement components and gypsum, cement products, mortar (polymer mortar, crack-resistant mortar, plastering mortar), and concrete. Especially suitable for plastering mortar with crack resistance requirements on the surface of steel wire mesh polystyrene board in internal and external wall and external insulation systems.
