Review shows improved compressive strength in high performance concrete by replacing cement with fly ash and silica fume, indicating potential for optimized mix design.
This paper formulates a simplified mix design procedure for HPC by combining BIS and ACI code methods of mix design and available literature on HPC. Based on the above procedure M70 mix are arrived at. These HPC mixes are tested experimentally for compression. This work primarily deals with the compressive strength characteristics such as water absorption super plasticizer used in high performance concrete a set of 23 different concrete mixture were cast and tested with different cement replacement levels (0%, 2.5%, 5%, 7.5%, 10% and 12.5%) of Fly ash (FA) with silica fume (SF) as addition ( 0%,2.5%,5%,7.5% 10 % & 12.5% by wt of Cement and/or each trial super plasticizer has been added at constant values to achieve a constant range of slump for desired work ability with a constant water-binder (w/b) ratio of 0.30.
