dc.description.abstractConcrete needs adequate curing in order to exhibit desired strength & durability properties. If the concrete receives insufficient curing, the cement will not hydrate fully. It is well known fact that higher fraction of cement getting hydrated produces the desirable compounds in the concrete. Moreover, it leads to an enhanced field performance of the concrete. Development of concrete with self curing (internal curing) ability can be the solution. Internal curing (IC) is curing the concrete from inside. The additives like Superabsorbent Polymer (SAP), Shrinkage Reducing Admixture (SRA) viz., Polyethylene glycol, propylene glycol, polyvinyl alcohol, paraffin wax, acrylic acid & pre-wetted light weight aggregates can be used as self curing agents. These materials facilitate extended hydration of the cement & cause lesser shrinkage. The research in the field of Self-Curing Concrete indicates the encouraging effects of these additives on degree of hydration, interface transition zone (ITZ), micro structure & other properties of concrete. The studies in the field show that Internal Curing has advantages such as reduction in shrinkage cracking, plastic shrinkage crack formation, water absorption, etc. The effectiveness of self curing has been proved in the laboratory, but the implementation on the field is yet not so common & encouraging. In this paper, an attempt has been made to discuss the mechanism & advantages of internal curing by incorporating Light Weight Aggregates. The paper also throws some light on how the internal curing can be practiced in the construction field. The practical considerations at the RMC plant are discussed. Key words: Concrete, plastic shrinkage, w/c ratio, autogenous shrinkage, internal curing, ITZ, chemical shrinkage, RMC plant.
