EXPERIMENTAL AND ANALYTICAL ANALYSIS OF FLEXURAL BEHAVIOUR OF SELF COMPACTING CONCRETE WITH GGBS

Abstract

Ground granulated blast furnace slag (GGBS), due to its pozzolanic nature, could be a great asset for the
modern construction needs, because slag concretes can be of high performance, if appropriately designed. The use of
GGBS as a cementitious material as well as fine filler is being increasingly advocated for the production of High
Performance Concrete (HPC), Roller Compacted Concrete (RCC) and Self-Compacting Concrete (SCC), etc. However,
for obtaining the required high performance in any of these concrete composites, slag should be properly proportioned
so that the resulting concrete would satisfy both the strength and performance criteria requirements of the structure. The
present paper is an effort towards presenting a mix design methodology for the design of GGBS concretes based on the
efficiency concept. The methodology will be successfully verified through a proper experimental investigation and the
GGBS concretes were evaluated for their strength characteristics. The results will indicate that the proposed method is
for proportioning mixes with maximum possible replacement of cement by GGBS for achieving strength.
