Properties of Concrete an overview ScienceDirect Topics

The main properties of concrete blocks are compression and tensile strength, absorption, dimensional accuracy, density, and shrinkage (Parsekian et al., 2012 ). In relation to density, units with a density of less than 1700 kg/m 3 are usually classified as lightweight, while normal weight blocks are those with a density greater than 2000 kg/m 3.get price
