Description
Summary:The high strength concrete has been extensively used in the past decades for several construction projects such as high-rise buildings, bridge construction, sports arenas etc. The prominent difference between strength concrete (HSC) and conventional concrete is the lower water-to-binder ratio, which imparts an overall better strength and durability to the concrete. However, certain undesirable characteristics, such as high shrinkage, high hydration heat, and early age cracking, can also be found in such concrete and therefore, require special consideration. The curing of high strength concrete therefore becomes an utmost important factor to minimise the effect of the aforementioned problems. This review article aims to outline the outcomes of various curing techniques and establish a systematic framework for evaluating their effect on high strength concrete. The curing methods for high strength concrete presented in the study include steam curing, oven curing, autoclave curing, dry curing, burlap curing, high and low temperature curing, vacuum curing and internal curing. The performance of the concrete depends on several factors and quantifying them simultaneously may not be feasible; however, summarising one of the major factors, i.e., curing, would provide valuable addition to the overall discussion. •A detailed review of various curing techniques employed for high strength concrete is presented.•Merits and demerits of different curing methods are compared.•Effect of curing methods on strength and durability of high strength concrete are compared.•Proposed mathematical models for internal curing are discussed.
