A SIMPLE TOOL FOR SELF COMPACTING CONCRETE MIX
ABSTRACT
• SCC can be made from any of the constituents that are generally used for structural concrete. In the mix design
• of SCC, the relative proportions of key components are generally considered by volume rather than by mass. On
• the basis of these proportions, a simple tool has been designed for self compacting concrete (SCC) mix design.
• In this paper, this tool has been evaluated with a SCC mix having 28% of coarse aggregate content, 35%
• replacement of cement with class F fly ash, 0.36 water/cementitious ratio (by weight) and 388 litre/m3 of paste
• volume. Crushed granite stones of size 20mm and 10mm are used with a blending 60:40 by percentage weight of
• total coarse aggregate. Detailed steps used in this tool are discussed in this study. This tool can also be used for
• self compacting mortar (SCM) design. It is practically seen that this simple tool is very much useful for the mix
• design of SCC with or without blended cement and with or without coarse aggregate blending..
