Durability properties of m60 gradeself-compacting concrete with partial replacement of cement by GGBS, lime powder and metakaolin

Abstract

In this investigation the Durability Properties of M60 grade Self compacting concrete (SCC) with partial replacement of cement by GGBS, Lime powder, and Metakaolin. Five mixes were prepared at 25% replacement of cement content with different admixture (.i.e.M1, M2, M3, M4&M5) at 0.34 w/c ratio and 1% super plasticizer dosage by cement content for maintaining required workability. Filling and passing ability were found out by slump test, V-funnel, L-box and U-box before casting the specimens. In this investigation M60 grade designed by means of Nansu method by fulfilling EFNARC guidelines for SCC. Durability properties tested under acid environment with H2SO4 and HCl and Sulphate environment with MgSO4 and Na2SO4 at curing period of 28 days. In this investigation the Lime-powder based mixes shows high durability comparatively to Metakaolin as well as addition of GGBS maintained sufficient compressive strengths.
