1. INTRODUCTION
2.21 Nan-Su Mix Design
The use of Self Compacting Concrete (SCC) is increasing day by day in India. The workability properties of SCC can be characterized(EFNARC, 2002) by filling ability, passing ability and segregation resistance.
The steps used in Nan-Su Mix Design for M35 Grade are given below. Step 1: Calculation of Coarse and Fine aggregate contents:
Compressive Strength of Different Grades of SCC Mix Using Portland Slag Cement (PSC) (75%), GGBS (25%) and Replacing 20% Fine Aggregate with Copper Slag is investigated by Chamarthy Krishnam Raju et al.[2], but target mean strength is not achieved for some grades of concrete. Hence present investigation is carried out with 30% of Cement replacement with GGBS.

Where, Wfa : content of fine aggregates in SCC (kg/m3), Wca : content of coarse aggregates in SCC (kg/m3),
The modified Nan-Su mix design for application to PSC concrete [2] is used. Master Glenium SKY 8233 super plasticizer is used. Mix grades M20 to M40 are considered in investigation.
