Characteristic Properties of Ternary Blend Concrete

Abstract

The use of supplementary cementitious materials (SCM) is the basic requirement in production of economic concrete with high
strength. The use of mineral admixtures or pozzolans such as silica fume (SF) and rice husk ash (RHA) in production of concrete not
only reduces the impact on environment due to its mass disposal from various industries, but also acts as replacement of cement
material in production of concrete which considerably reduces the present demand on manufacture of cement. The main objective of
this experimental work was to study the properties of concrete using different admixtures by adopting total of 25%-30% replacement
of cement material. Combinations of various mineral admixtures with varying percentage and use of chemical admixture to reduce
water content was adopted. The above experimental work was done on M 30 concrete. Casting of 60 numbers of specimens was
undertaken for testing compressive strength and split tensile strength. From the results of present experimental works, concrete
containing 15% Rice husk ash and 12% Silica fume by partial replacement of cement yielded higher compression and split tensile
strength.
