WebFeb 28, 2024 · Concrete Admixtures: Air-Entrainment. Air entrained concrete can increase the freeze-thaw durability of concrete. This type of admixture produces a more workable concrete than non-entrained concrete while reducing bleeding and segregation of fresh concrete. Improved resistance of concrete to severe frost action or freeze/thaw cycles. WebA concrete mix consists of the combination of five major elements such as cement, water, coarse aggregates, fine aggregates (i.e. sand), and air in specific proportions to obtain concrete of the required grade. Other elements include pozzolanic materials and chemical admixtures incorporated into the mix to obtain certain desirable properties.
WebSelf-consolidating concrete (SCC) is a well-known type of concrete, which has been employed in different structural applications due to providing desirable properties.
