Description 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 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.
Usage of cement anti-crack agent
Cement anti-crack agents can be used to solve the crack problem of bridges, highways, runways, dams, cement products, mortar.
Especially suitable for various products of lightweight concrete.
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.
Instructions of cement anti-crack agent
The recommended dosage is 1.5-3kg/m3, and the precise usage needs to be determined after debugging;
When using it, it is best to dissolve the anti-crack agent in the required water, and then add it to the mixer to stir, and then it can be used.
Storage and transportation of cement anti-crack agent
(1)The anti-crack agent packaging specification is 20 kg/bag, non-toxic and non-flammable, and can be transported as general cargo;
(2)The anti-crack agent should be stored in a cool and dry place to avoid rain and moisture, and the shelf life is 24 months.
