A uniformly blended mixture of portland cement, sand, rock, reinforcing fibers and other special additives engineered to provide superior resistance to cracking and shrinking. Specifically designed for exterior applications where freeze-thaw conditions occur. Synthetic reinforcing fibers eliminate the need for reinforcing wire mesh or rebar for non-critical applications. Use in concrete applications greater than 2 in thickness, achieves 5000 psi strength. For interior or exterior use. Meets ASTM C-387 specifications.
