Strength and durability properties of high strength self compacting concrete

Abstract

Self compacting concrete (SCC) is highly flowable, non-segregating concrete that fills uniformly and completely every corner of formwork by its own weight and encapsulate reinforfcement without any vibration, whilst maintaining homogeneity. In this current construction practices SCC plays a very vital innovation or alternative to normal concrete. SCC is produced by the same materials as that used for the production of normal concrete. But the properties of every material used for the production has a vital influence on the features of fresh and hardened state of SCC. Designing a lower grade with required properties may be easier, so in this paper SCC with higher strength will be designed as per Indian Standard codes. Flow test, V-Funnel test, l-Box test for fresh or plastic concrete and compressive strength on 7th, 28th and 180 days were carried out to observe the strength of concrete. Chloride and Sulphate content were analyzed during 180 days to know about its durability. The results show that this mix produces a very good quality M60 grade SCC.
