Prestressed casing grouting agent
It is a ready-to-use powdered additive for pouring methods. It can cause the cement mixture to expand before setting. The expansion phenomenon is caused by some very uniform and densely distributed hydrogen-containing tiny bubbles inside. These very tiny gaps can make the cement binder highly frost-resistant. The special ingredients contained in it include an effective additive that can reduce the separation of water in the cement mixture (bleeding), have an early strength effect and can reduce water consumption.
15kg/barrel
Water-cement ratio: 0.45
Expansion rate: 3% to 15%
The expansion rate of cement slurry for prestressed casing grouting is about 3% to 10%
★ Will not shrink after solidification, and can be used on wet surfaces
★ Prestressed steel key anti-corrosion protection function
★ High flow and high expansion for the best construction benefits
★ Can reduce water consumption after adding
★ Durable effect and all cavities can be densely filled
It is used for prestressed casing grouting and filling grouting in loose strata or rock holes, achieving the functions of expansive cement, expansive cement mortar and expansive concrete.
