[PDF] A Review on Self Curing Concrete | Semantic Scholar

Curing of concrete maintains satisfactory moisture content in concrete in its early stages so as to develop desired properties. Self-cured concrete is one type of concrete, which cure itself by retaining water (moisture content) in it. The self-curing process of concrete takes place from inside to outside, which reduces the autogenous shrinkage and self-desiccation. It is mainly practiced …

Durability of Lightweight Self-Curing Concrete

Lightweight concrete can significantly reduce a dead load of structural concrete elements compared to normal-weight concrete. Self-curing concrete is one of the innovative concretes that can be cured without using conventional curing regimes. Lightweight concrete is made from lightweight coarse aggregates instead of natural coarse aggregates.
