11.5.2 Light-weight concrete. Light-weight (aggregate) concrete ( ρ ≤ 1900 kg/m 3) is of smaller modulus of elasticity, sharp stress–strain curve, and fails suddenly (see Section 4.2 ). The mechanical behavior of the reinforced beam of light-weight concrete is similar to that of ordinary concrete, but shows larger deflection, wider crack ...
