标题：EFFECT OF CURING REGIMES ON COMPRESSIVE
STRENGTH AND CORRESPONDING PERFORMANCE
EVALUATION OF PALM OIL FUEL ASH AND
HIGH-PERFORMANCE CONCRETE: A REVIEW
摘要：The major component of construction material concrete is distinguished for its durability and strength against compressive loading. The strength development of concrete largely depends upon hy- dration rate, w/c ratio, shrinkage, and cracking po-tential. Curing is the prime factor accelerating and facilitating the rate of strength development of con- crete. The curing type, temperature, duration, and environment have a significant impact on strengthand mechanical properties. Carbon dioxide curing, hybrid curing, autoclaved & non-autoclaved curing, and microwave curing are compared with air, water, and conventional heating regimes and it is observedthat former techniques exhibit higher strength in a shorter period, i.e. Microwave curing produces around 90% of its 28 days strength in first 7 days. Additionally. this review involves the analysis of ef- fects of pH and different curing regimes on strength and mechanical properties of various concretes such as ordinary portland concrete (OPC), palm oil fuel ash (POFA), high-performance concrete (HPC), ul- tra-high performance concrete (UHPC) and recycled aggregates (RA) at all ages of 1,3,7,14 and 28 days. Subsequently, the sustainable replacements of com-posite matters and OPC are self-consolidating con-crete (SCC), reactive powdered concrete (RPC), fi- ber reinforced concrete (FRC), and green cement & concrete, etc., which possess high strength and sus- tainability.
