Abstract
This paper presents the performance of Self Compacting Self Curing Concrete (SCSCC) which consists of 30% of class C fly ash for the replacement of cement, 100 % of Manufactured Sand (M sand) for river sand, water reducing admixture of Glenium B233 and self-curing compound of Polyethylene glycol (PEG 400). M 25 concrete mix is designed with different proportions of PEG 400 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, compressive strength and split tensile strength. The fresh properties of SCC are determined as per EFNARC and found satisfactory. It is observed that the addition of 1% of PEG 400 by weight of cement gives better compressive strength and it is taken as optimum dosage for making SCSCC. Glenium B233 of 0.6 % is added in SCSCC to improve the workability. The compressive strength and split tensile strength of SCSCC are found satisfactory as that of conventional concrete. In order to check the adoptability of the developed SCSCC for structural purpose, a beam-column joint is made. Non-destructive tests are performed on beam-column joints, and the quality and compaction effect of concrete are compared. Destructive tests on beam-column joints showed better results for SCSCC specimen in terms of load carrying capacity, deflection and initial stiffness than the conventional concrete joint. © 2014 CAFET-INNOVA TECHNICAL SOCIETY.
