Utilization of Foundry Ash as Replacement to Fine Aggregate in Self Compacting Self-Curing Concrete

With improvement in technology, concrete had been endangered to various techniques and variation. In spite of these variations, it exhibits upright mechanical properties. Curing promotes hydration of cement, controls temperature and movement of moisture from and into the concrete. To continue hydration, the relative humidity inside the concrete should be 80%. Self-curing is the process in which the water is retained in the concrete and evaporation of water is also reduced. Self-compacting concrete (SCC) is a concrete that settles by its own weight, even in the presence of congested reinforcement with full compaction. It does not need any external vibrator to compact. In this project the performance of Self-Compacting Self-Curing Concrete (SCSCC) which consists of 25 to 100 % of foundry ash in place of river sand, BS-17 3P which is a liquid chloride free water reducing and super plasticizing admixture and self-curing compound of KEM Cure Aid 10 W. M 30 concrete mix is designed with different proportions of KEM Cure Aid 10 W from 0% to 2% by weight of cement. Fresh and hardened properties of Self-Compacting Concrete (SCC) and Self-Curing (SC) are studied in terms of flowability and workability, and Mechanical properties. The fresh properties of SCC are determined as per EFNARC.
