🕑 Reading time: 1 minute Lightweight concrete floor provides more efficient strength-to-weight ratio in concrete floor systems when compared to other conventional concrete floor systems. The reduced quantity of concrete and steel reinforcement offsets the marginally higher cost of lightweight concrete floor systems. These floors are constructed for different purposes but the
1999-1-1 · A general value for concrete''s coefficient of thermal expansion is about 5.5 millionths/° F. If an unrestrained, 100-foot-long slab on grade was exposed to a 100° F temperature drop throughout its cross-section, it would contract about .66 inch (100 feet x 12 inches/foot x 100° F x .0000055). Since the slab is restrained by friction between
