Abstract

Abstract: Bridge design plays a vital role in the field of civil engineering. The materials to be considered, method of construction is an important factor along with the codal provisions. Self-compacting concrete (SCC) has been a popular choice for civil engineering projects due to its ability to create cohesive concrete. This article discussed the possibility of producing an SCC without employing a superplasticizer and just utilising locally available mineral admixtures, with a well graded coarse aggregate size of 25 mm, which is a completely a new method of preparation of SCC. The enhanced features were evaluated and verified in accordance to EFNARC standards. The mechanical properties of SCC without super plasticizer are compared with M25 Conventional Concrete. During the preliminary study, the mechanical characteristics of the SCC produced using the mentioned technique. Followed by the evaluation of the flexural behaviour of the SCC for beam specimens. Based on the findings, finally it can be concluded that this kind of SCC is a potential and successful alternative to the conventional type of SCC produced using Glenium B233 products, as well as being cost effective.
