RQS ? -S1 can effectively decrease micro-crack propagation as a result of plastic shrinkage, drying shrinkage and concrete thermal stress, and delay macro-crack formation and propagation. RQS ? -S1 significantly improves the crack resistance, tensile resistance, abrasion resistance and fatigue resistance of concrete.
