ABSTRACT:
This paper presents the evaluation of mechanical properties of binary blended concrete. Binary blended concrete have been developed by the individual replacement of Supplementary Cementing Materials (SCM’s) like Fly-ash, Silica fume and Metakaoline. The results of binary blended concrete are compared with those of control concrete. The main purpose of this investigation is to develop confidence among user agencies in India to use mineral and chemical admixtures in a desirable proportion in most of the construction works. The paper presents experimental studies conducted on M30 grade of concrete using SCMs and chemical admixtures in various proportions. The cubes and cylindrical specimens after de-moulding were stored in curing tanks and on removal of cubes and cylinders from water the compressive strength and split tensile strength were conducted at 7days, 28days, 90 days and 180 days. The test results were compared with individual percentage replacements of SCMs for M30 grade concrete with and without chemical admixture.
