Overview of Concrete Crack-reducing Admixture

Cement anti-crack agent is Trunnano'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, wear resistance, and earthquake resistance.

Usage of Concrete Crack-reducing Admixture

Concrete crack-reducing admixture can be used to solve the crack problem of bridges, highways, runways, dams, cement products, and mortar.

Especially suitable for various products of lightweight concrete.

Characteristic of Concrete Crack-reducing Admixture

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.

Package and transportation

Instructions for Concrete Crack-reducing Admixture

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.

Package of Anti-crack Agent

Packaging: The anti-crack agent packaging specification is 20 kg/bag, non-toxic and non-flammable, and can be transported as general cargo. If special specification packaging is needed, it can be customized in advance.

Storage of Anti-crack Agent

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.



How to choose a suitable concrete crack reducing agent?


Choosing a suitable concrete crack reducing agent requires considering factors such as engineering requirements, concrete mix ratio, and construction environment. Crack reducing agents should be selected that have good compatibility with the concrete materials used, stable performance and significant effects.


How to use concrete crack reducing agent?


How to use concrete crack reducing agents varies depending on the type. Generally speaking, the crack reducing agent should be mixed into the concrete in the specified proportion and mixed thoroughly. In some cases, crack reducing agents need to be added before or during the concrete pour.


What effect does concrete cracking agent have on the performance of concrete?


Concrete crack reducing agents can significantly improve the shrinkage performance, crack resistance and toughness of concrete. The use of crack reducing agents can reduce the drying shrinkage of concrete and increase its tensile strength and toughness, thereby improving the durability and stability of the concrete structure.


What is the dosage of concrete crack reducing agent?

The amount of concrete crack reducing agent added depends on its type and use. Generally speaking, the amount of crack reducing agent should be within the specified range and appropriately adjusted according to project needs. Excessive use may affect other properties of concrete.


Are concrete crack reducers compatible with other additives?


Concrete crack reducing agents should be compatible with other additives. When using other additives, testing and verification should be conducted first to ensure compatibility and synergy between the crack reducer and other additives.


What impact do concrete crack reducers have on the environment?


Concrete crack reducers have a low impact on the environment. Most crack reducing agents are water-based, contain no harmful substances such as volatile organic compounds, and are environmentally friendly. During use, relevant environmental protection regulations and requirements should be followed.
