Sand combination is Portland cement and sand, since the name implies, and is also designed for use at half-inch thick and as an awesome offer as two-inch deep mold thickness. Sand combination utilized as directed and in accordance with ASTM C-387 yields a compressive durability of 5,000 psi best after 28 days.

Where to take advantage of Bags of Sand combination - Cement tiles and slender brick veneer, that are ordinarily about half-inch thick or thinner are finest produced using a Sand Mix.
