High Performance Expansive Agent For Concrete Expansion Control SK-201

High-Performance Expansive Agent For Concrete Expansion Control SK-201 Highly Efficient Plastic Expansion Agent

The alkaline water reacts with these silicates and forms a so-called alkali calcium silicate hydrate. This mineral accumulates moisture in its structure, which causes it to expand and gradually crack the concrete from within.

Thermal Expansion and Contraction. Materials expand or contract when subjected to changes in temperature. Most materials expand when they are heated, and contract when they are cooled. When free to deform, concrete will expand or contract due to fluctuations in temperature.

Note: The expansion test is tested according to the test standard of 0.015% dosage, and the implementation standard is: JTG / T3650-2020 Technical Specification for Construction of Highway Bridge and Culverts. >
