Reduce drying shrinkage for concrete
Teba SH-CONTROL is a transparent liquid, based specialized polymers have potential use in bridge decks, critical floor slaps and buildings where cracks, curling, and warping
As concrete dries, water is removed from the capillary pores and meniscus due to surface tension ( surface tension also act ) on the solid phases and tend to draw the walls of the pore together.
As the water meniscus recedes into smaller and smaller pores the surface tension forces increase, causing the concrete to shrink more .
The Teba SH-CONTROL reduce the surface tension of the liquid phase, which reduce the forces exerted on the pore walls thereby .
