COMPARATIVE STUDY ON COMPRESSIVE STRENGTH OF SELF COMPACTING CONCRETE WITH HIGH VOLUME OF FLY ASH AND GGBS

Abstract

The boon of industrial revolution is the great transformation of rural to urban due to the growth of industries. At the same time our earth has to face the threat to manage the industrial waste. To Ensure the 12th SDG goal, sustainable consumption and production patterns, the ingredients of SCC like fine aggregate and binding material can be replaced and reused by the industrial waste. The application of Self-compacting concrete (SCC) was improved widely in the construction industry to overcome the labour scarcity. Fly ash and GGBS the residue of the iron and steel plant waste can be replaced to cement in high volume to achieve the SCC workability properties.  Nine mix designs with replacement of fly ash and GGBS were designed along with one control mix. In all mix design the weight of binding material is maintained the same whereas the water to cement ratio is adjusted with the by product weight ratio.  The wet concrete tests were done for each batch and the results are compared to the EFNARC limiting values. [5]. The characteristic cube strength was found under universal testing machine at 28 days after proper curing. The target strength achieved by the SCC cubes with varying percentages, ranges from 26 to 48MPa. The strength and the cost based analysis can lead to produce self compacting concrete with fly ash & GGBS economically.
