EVALUATION OF STRENGTH AND RESISTANCE CHARACTERISTICS OF M25 CONCRETE MIXES USING GGBS AND ROBO SAND FOR RIGID PAVEMENTS

In this we determine the suitability of GGBS (Ground Granulated Blast Furnaces Slag) as a partial replacement of cement an a Robo sand as a partial replacement of fine aggregates. It has been watched that in late 10 years, the nature of regular sand is debasing day by day and nowadays the construction industry in India is confronting a noteworthy issue because of intense lack of normal river sand. The work was undertaken to evaluate the strength characteristics of concrete proportioned to have five levels 0 % 15% 30% 45% 60% of cement replacements with GGBS and fine aggregates with robo sand. The GGBS and Robo sand makes concrete more impermeable and denser as compared to ordinary Portland cement. The strength of GGBS and robo sand concrete is better compared to the plain concrete. The following project also gives an idea about the characteristics of skid resistance, and also methods to reduce skid resistance on concrete cubes.
