 — Concrete is very strong in compression and not so strong in tension. In a slab, tension is often created by bending. When a piece of concrete bends, it is in compression on one side and tension on the other side. A concrete slab may bend concave up (like a smile) if the subgrade has a soft spot in the middle, putting the bottom in tension.

 — The ASTM C33 standard covers wet and dry screening test specifications as a general requirement for the grading and quality of fine and coarse aggregate materials. Fine aggregates can either be natural sand crushed stone sand or a combination thereof. Fine aggregates should be free from harmful amounts of organic impurities.
