    Portland cement concrete industry has grown-up extremely in recent years. It will drastically increases uses cement for infrastructure development throughout worldwide. However, Portland cement concrete shows harmful effects such as durability and CO2 emission. Many concrete structures have shown serious worsening, way before their proposed service life, mainly those structures constructed in a corrosive environment such sea shore and water logged areas. India being largest coal fly ash producer in the world, from thermal power plant, that is waste product and available in huge quantity, with very minimum rate. The waste product as fly ash is to be used as a cement replacement material in concrete and to achieve a very good strength of geo-polymer concrete. A trail mixture design of cement replacement materials such as Fly ash, GGBFS where used. A mix proportions of 10% GGBFS & 90% fly ash, 20% GGBFS & 80% fly ash and 30% GGBFS & 70% fly ash. From above mix proportion a best result is obtained 30% GGBFS & 70% fly ash, that is compressive strength is 42.44 N/mm2 and spit tensile strength is 3.345 N/mm2. Above strength parameters of geopolymenr concrete is good for construction residential and low rise building. By using geopolymenr concrete, we can reduce emission CO2 from construction industry.

    Self-compacting concrete has a very important role in the construction of tall structure, because such structures are designed for higher grade concrete as well as higher grade of steel, with less dimensions of structural components. The main execution difficulty of normal concrete was raised due to congestion of reinforced in the structural components, where self-compacting concrete (SCC) is compacted under its own weight without compaction or vibration as well as it has excellent fresh state properties without segregation and bleeding. For present experimental work, first to adopt optimum dosage of superplasticizer is 2.5% and w/c ratio is 0.28 by trial and error method, with accepting fresh properties of SCC results. Later the study is carried by replacement of silica fume with cement 4, 8, 12, and 16% of silica fume by trial and error method. The results obtained by replacement of 12% of silica fume for 7 days compressive strength is 40.1 N/mm2 and for 28 days compressive and split tensile strength are 72.6 and 6.9 N/mm2, respectively. For a proportion of 2.5% superplasticizer, 0.28 w/c, 12% of silica fume, 506 kg/m3 of cement, 700 kg/m3 of fine aggregates and 833 kg/m3 of coarse aggregates were produced very good compressive strength and split tensile strength, and the trial and error SCC mix design can be adopted for above M70 grade concrete.
