STUDY OF SELF-COMPACTING CONCRETE PAVEMENTS FOR CURLING STRESS BUILDING

CIVIL ENGINEERING

Fly ash addition improves the fresh state properties of SCC mixes with CS at lower super plasticizer dosage. Hence, the addition of fly ash helps in economizing the SCC mix due to reduced HRWR dosage. SCC mix design can be powder based or admixture based or a combination of both. Use of pozzolanic or inert additions as cement replacement materials helps to improve fresh state properties of SCC mix at lower HRWR dosage and does not require VMAs to stabilize the fresh mix. In the present study, powder based mix design was adopted with use of Class C fly ash as a cement replacement material. The addition of fly ash as a cement replacement material in SCC mixes helps in improving the carbon foot print of the SCC mix. Conceptually SCC mixes are characterized as high cement content mixes (cement content in excess of 500kg/m3). Addition of fly ash as a cement replacement material ensures conservation of environment due to reduced emissions in cement manufacture as well as recycling of an environmental hazard.
