Concrete quickly took over the world. Nowadays we can not imagine life without it. Despite it's popularity, concrete has few flaws.

SAP additive has been found to reduce autogenous shrinkage, promote cement hydration, improve rheological properties, improve self-healing, and increases frost resistance.
