Durability Of Concrete

The biggest disadvantage of conventional concrete is brittle and hard, in addition, its durability is not high. The low durability of concrete is due to the presence of calcium hydroxide at the intersection of coarse aggregate particles and hard cement powder. The introduction of coconut fiber and polyvinyl alcohol (PVA) fibers into the concrete to improve the durability and flexibility of the concrete. In addition, the article also considers the effects of other additives such as rice husk ash, silica fume to study the performance of the structure as well as its durability when joining concrete mixes to create flexible concrete movable and more flexible than conventional concrete.
