What Is Mass Concrete | Properties of Mass Concrete | Advantage of Mass Concrete | Disadvantage of Mass Concrete |How Much Mass Density of Concrete

CivilJungle

Mass Concrete: Large bridge piers , foundations , and such as dams like the massive structure , the mass concreting technique is used. For also, mass concrete strength , economy, uniformity, and other factors considered should take into account. The temperature shrinkage is the major problem in mass concrete work.
