Use of OPC causes the emission of CO 2, which is a global house gas, to reduce the usage of OPC (Ordinary Portland Cement), GPC (Geopolymer Concrete) can be used as an alternative. To study the impact of molarity in GPC and compared with conventional concrete. The grade of concrete tested are M30 and M40 by using OPC 53 grade to compare the strength and geopolymer concrete M40 by using GGBS with River sand and M-sand. In geopolymer concrete when strength compares with different molarities 8M to 16M are used in this project work. In GPC strength is directly proportional to the molarity of NaOH. The mechanical properties are conducted to find out the strength. Different molarities were conducted with ( slump test; compaction factor) workability strength of concrete. The different acid test is conducted in durability (i.e., HCl, water absorption test, MgSO 4 , H 2 SO 4 , NaCl). Geopolymer concrete energy absorption is more when compare the normal concrete. The strength increases to increasing the molarity of concrete in GPC.
