SAP for concrete maintenance
Pubdate:2022-03-15

High-performance concrete with high strength & durability is widely used in the construction field, due to its low water gel, drying & deformation is commonly happened. Shrinkage is usually caused by pores relative humidity reduce, to solve the problem of cracking, firstly shall control the shrinkage of concrete, that is to say, to improve the inside moisture content of concrete.

As a new & functional material, super absorbent polymer(SAP in short) is added into concrete, it can absorb 30-40times of its own weight of water, absorb and release slowly, the saturated SAP’s inner moisture can prevent the loss of water outwardly.When the temperature increases, the moisture migration occurs, moisture will break the adsorption of SAP, and the humidity migrates from high potential to low potential, reduce the migration potential gradient, then make the concrete inner moisture distribution evenly and reduce the humidity difference capability.

The adding of SAP in concrete can prevent concrete cracking and increase the strength of concrete , improve concretes performance of impermeability and antifreeze. Its recommended to use concrete that added SAP in some arid , windy , and cold places.
