Abstract

Concrete in today’s world has a major role in construction industry and is the most frequently used material in construction having high compressive strength and durability. Concrete needs proper curing to achieve desirable properties and insufficient curing affects the strength of concrete badly. Nowadays, Internal Curing (IC) has come into research which has many positive advantages in terms of enhancement of properties of concrete. By utilizing the water that is already in the concrete and adding certain amounts of self-curing agents, this method of curing is used that helps in the curing of the concrete internally. It is done ‘from the inside to outside’ using internal reservoirs. Also, shrinkage reducing agents like Polyethylene-glycol and Light-Weight Aggregates (LWA) are used to achieve effective curing results. In cement-based materials, Superabsorbent Polymer (SAP) is generating a lot of debate. This study offers a review for cement-based materials containing SAP for different w/c values, the conclusions on the properties including workability, mechanical characteristics, and durability of SAP-modified concrete and SAP cement-based materials. In most of the studies found on high-performance concrete, w/c is restricted to 0.3 - 0.35. Hence, properties are described on the basis of different w/c ratios as mentioned in this paper. Total 60 articles are reviewed (including 59 research paper and 1 review report) in this study.
