Abstracts: This paper presents an experimental investigation on the effect of partial replacement of cement by Admixture (Metakalion and Fly ash) by various percentages viz 0%, 3%, 6%, and 9% on the properties of concrete of proportion 1:1:2, when it is subjected to COMPRESSIVE FORCE. An aggregate of 20mm size was used and water/cement ratio 0.50 was used in this investigation. Concrete specimens of size 150 x 150 x 150 mm were casted to find residual compressive strength. Sizes of specimens were casted and cured as per IS specification. After 7 days & 28 days water curing, the concrete specimens were kept 10 to 15 minutes air dry and COMPRESSIVE TEST was performed on concrete cubes. Before testing, they were weighed accurately. The various results which indicate the effect of replacement of cement by metakalion and fly ash on concrete are presented in this paper to draw useful conclusions. The results were compared with reference mix. Comparison test results indicate that use of replacement cement by metakalion and fly ash. HPC has increase metakaolin then fly ash up to 4%.
