Comparative Investigation on Properties of Self Compacting Concrete and Conventional Concrete

The primary aim of this study is to investigate the strength properties and flexural behaviour of beam, of M40 grade self-compacting concrete made with fly ash, GGBFS and a mixture of both in different proportions and compare its values with M40 grade conventional concrete. Conventional concrete is designed by using IS: 10262-2009 and SCC is designed using Modified Nan Su method. For this purpose cement is replaced by weight in three different proportions of 10%, 20% and 30% by fly ash and GGBFS respectively. Also 20 % of cement was replaced by fly ash and GGBFS in different proportions such as 70%:30%, 60%:40% and 50%:50%. The characteristics of SCC like passing ability, flow ability and resistance to segregation have been checked using slump flow, L box test and V funnel test as per EFNARC guidelines. Specimens are tested for compressive strength, flexural strength, splitting tensile strength.
