Book Description
Membrane curing compounds are widely used to cure concrete in highway construction. The function of these compounds is to form a membrane that helps retain moisture in the concrete slab, otherwise lost through evaporation. The amount of evaporation loss varies as a function of the environmental conditions and the temperature of the concrete mass during the curing period. This rpeort provides an evaluation of the performance of membrane curing compounds as related to concrete material properties such as tensile and flexural strength, stiffness, surface durability, and density. In addition to traditional testing methods, the non-destructive, in-situ, Spectral Analysis of Surface Waves method is also used to observe and measure material properties as a function of time. Testing can start at initial set or when the modulus of elasticity for concrete is about 10,000 psi.
