Now a day’s research is more concern on the successful utilization of different mineral admixture so as to cut down the environmental pollution caused by cement industries throughout cement production. Self-Compacting Concrete (SCC) is a new generation concrete has been developed without compromising the strength characteristics with minimum time and labour cost. So to make more economic and environmental friendly concrete, two mineral admixtures (waste products of the industries) i.e. Silpozz and Lime Stone Powder (LSP) were used during this experimental work. The aim of this study is to evaluate the fresh and hardened properties of the conventional concrete (CC) and Self Compacting Concrete (SCC) containing mineral admixtures. Cement is partially replaced with Silpozz and LSP as 0%, 10% and 20% for both CC and SCC. Total ten numbers of concrete mixes have prepared for M30 grade of concrete. Fresh concrete properties of CC have evaluated by slump test and for SCC, slump flow, T500, V-funnel and J-ring test were conducted. Hardened concrete properties were evaluated after 7 and 28 days for compressive, split tensile and flexural strength test. The desired amount of superplasticizer (SP) is used in SCC to make the concrete workable. The test results indicate that the 20% replacement of Silpozz influences the mechanical properties of concrete as compared to LSP replacement.
