COMPRESSIVE AND TENSILE STRENGTH STUDIES ON CEMENT CONCRETE WITH PARTIAL REPLACEMENT OF CEMENT BY FLY ASH AND FINE AGGREGATE BY GRANULATED BLAST FURNACE SLAG

Globally construction industry has enormous growth year by year. This leads to increase in need for construction materials, which can be obtained from the natural resources. By this the natural resources have depleted at a faster rate and cement production leads to higher amount of CO2 emission. This directly leads to the environmental hazards for human and aqua life. So there is a necessity for finding the alternative material in order to conserve the earth for future generation. The growth in industrial progress leads to the increased production of industrial waste. Hence industrial waste materials management too is a challenging problem. There by handling and disposal of industrial waste is a big issue in this contemporary world. Keeping all the above problems in view, in this present experimentation, an attempt has been done to utilize the industrial waste products such as fly ash and granulated blast furnace slag in cement concrete by way of replacing them to cement and fine aggregate in the production of concrete. The percentage of replacement of sand by granulated blast furnace slag are 0%,20%, 40%, 60%, 80%,100% and keeping fly ash as 25% constant for cement. This research is focused on the combined behaviors of granulated blast furnace slag and fly ash in study some of the strength properties. It can be seen that the effective utilization of both the materials will lead to the restriction of environmental hazards. In this paper we focused on hardened properties of concrete, i.e. compressive strength and tensile strength.
