Cement is the major constituent of concrete which is produced by natural raw materials like limestone rock, clay and chalk etc. These are produced by blasting quarries. Industrial wastes like Ground Granulated Blast Furnace Slag (GGBS) show chemical properties similar to cement. Use of pozzolanic material like GGBS will reduced the cost of concrete and helps to reduce rate of cement consumption. This research explains about strength and durability analysis of GGBS concrete which gives assurance

This research work focuses on strength and durability characteristics of M40 grade concrete with replacement of cement by GGBS with 10%, 20%, 30%, 40% and 50% and replacement of natural sand by Msand with 50% and compares it with conventional concrete. Compressive, split and flexural test were conducted on concrete specimens for strength analysis and for durability studies RCPT, Sorptivity and Acid attack test were conducted. HPC mixes have also indicated better resistance to chloride when tested in RCPT (Permeability Test), Sorptivity and to the attack of chemical such as HCL acid when the HPC mixes were exposed to this acid for 30 days period.
