STUDY OF DESIGN OF HIGH STRENGTH CONCRETE MIXES , ESTIMATION OF WORKABILITY AND EFFECT OF SUPER PLASTICIZER ON THE COMPRESSIVE STRENGTH .

Abstract

It is observed that workability of high strength concrete get reduced till the time of placing of the concrete . There fore ,an attempt has been made to study the design of high strength concrete mixes, effects of super plasticizer, estimation of workability on the compressive strength of high strength concrete. There fore , four types of cements i.e ,shri ultra cement (53 grade), j . k. Cement (53 grade ) , Birla cement (53 grade) , A.C.C. Cement (53 grade ). In the present work, the superplasticizer is added to the mixing water ,as well as to the resulting high strength concrete also at regular intervals to study its effects on workability and compressive strength of high strength concrete.
