Advantages / Disadvantages. High-strength concrete resists loads that cannot be resisted by normal-strength concrete. Not only does high strength concrete allow for more applications, it also increases the strength per unit cost, per unit weight, and per unit volume as well.
12-09-2017· The following are the disadvantages of concrete : Due to low tensile strength, concrete is required to be reinforced to avoid cracks. In long structures expansion joints are required to be provided if there is large temperature variance in the area. Construction joints are provided to avoid cracks due to drying shrinkage and moisture-expansion.
Disadvantages of ordinary portland cement: It cannot be used for large-scale concreting because it has a higher heat of hydration than PPC. The durability of OPC is lower than the PPC. It produces relatively less solid concrete than PPC, so pumping the concrete becomes a bit difficult.
