NICMAR Journal of construction managementSummary: Self Compacting Concrete (SCC) is a type of concrete that gets compacted under its self-weight. SCC is a concrete that can be placed and compacted into every corner of a formwork; purely by means ofits self-weight, eliminating the need ofeither external energy input from vibrators or any type ofcompacting effort. This paper discusses about Self-Compacting Self-Curing Concrete, which uses Super Absorbent Polymers (SAP) as a self-curing agent. There is a significant influence on the strength ofthe concrete because ofinternal curing using SAP. However, ifthe quantity ofSAP added in the concrete exceeds the limit, it may lead to additional void formation in the concrete mass, which in turn would have a negative effect on the hardened concrete. This effect ofSAP on concrete leads to improvement in workability and placing on concrete. This paper focuses on the physical properties ofhardened SAP induced concrete, and compares them with ordinary M40 grade concrete. The concrete mix limits the percentage ofsuperplastizer to 2 % and varies the percentage ofSAP. Nearly 18 trials were carried out, from which the mix for M40 grade ofconcrete and percentage ofSAP to be added is obtained. All the trials satisfied the workability tests specified in the European Federation ofNational Associations Representing for Concrete (EFNARC).
