EXPERIMENTAL STUDY ON STRENGTH OF CONCRETE BY USING METAKAOLIN & OP

-

concrete is that pourable mix of cement, water, sand, and gravel that hardens into a super-strong building material. Supplementary cementing materials (SCM) have become an integral part of concrete mix design. these may be naturally occurring materials, industrial wastes or, by products or the ones requiring less energy to manufacture. some of the commonly used scm are fly ash, silica fume (SF), GGBS, rice husk ash and metakaolin (MK), etc. metakaolin is obtained by the calcination of kaolinite. it is being used very commonly as pozzolanic material and has exhibited considerable influence in enhancing the mechanical and durability properties of concrete. in this paper , experimental study was carried out on M 20 grade and M 50 grade of concrete. in this concrete we have tested slump test , Vee bee test and Compacting Factor of concrete
