Abstract: Self- Compacting Concrete (SCC) is a special type of concrete that is able to flow and compact under its own weight and can occupy all the spaces in the form without any vibration effect and at the same time cohesive enough to be handled without bleeding or segregation. SCC is a highly flowable concrete which is able to fill the formwork with admixtures such as Fly Ash (FA), Silica Fume (SF), Ground Granulated Blast Furnace Slag (GGBFS), and Metkaolin (MK) etc. There are no standard mix design procedures available for SCC. In the present work, Normal Vibrated Concrete (NVC) and SCC were developed for M30 grade. NVC is designed by using IS code method and SCC is designed by using Nan Su method. Study of SCC with and without mineral admixtures such as SF and FA was made separately at different percentages as 10%, 20%, and 30% respectively by using appropriate dosage of super plasticizers (SP) and viscosity modifying agent (VMA).The workability properties of SCC such as filling ability, passing ability and segregation resistance are evaluated using workability tests such as slump flow, V-funnel and L-Box tests. Strength properties such as compressive strength, split tensile strength and flexural strength of NVC and SCC were also studied.
