Abstract

The use of SCC in actual construction is still less in India. Lack of awareness, Technical data could be cited as the main reasons. For adoption of any new material or technology, it is generally needs proven performance over traditional materials. Considerable research is carried out in India towards the technology development so that SCC could soon find a place in the Indian Construction Industry. Its technical and Economical advantages are well documented and published especially through full-scale experimental casting and testing program.

In the present experimental investigation the main concentration is focused on durability properties of self compacting concrete mixes. The number of trail mixtures are used and tests such as Slump Flow, V-Funnel, L-box etc. are conducted for their permissible limits, then the final proportions of ingredients and admixtures have been finalized for M30, M 40, M 50 and M 60 grade concretes. Then investigations are carried out for Percentage loss in compressive strength for the specimens immersed in H₂So₄, HCl and Na₂So₄ Solutions for 28, 56, 90 and 180 days and Permeability aspect.
