The usage of practical advancement in structural building society has prompted the utilization of new materials with low environmental effects. One of the most commonly used construction material in the world is concrete, which is normally produced by OPC. However, the production of OPC has prompted ecological worries over the creation of CO2. Almost to create 1 ton of OPC 1 ton of CO2 is discharged to the atmosphere. With a specific end goal to diminish the utilization of OPC and CO2, the new concrete has been created, that is GEOPOLYMER CONCRETE. Latest research has demonstrated that it is conceivable to utilize fly ash or slag as a binder in concrete by activating them with alkali components through a polymerization procedure. This paper reports the point of interest of the test work that has been embraced to examine the strength and durability properties of ultra-fine slag and processed fly ash mortar mixes. At first specimens were casted for normal GGBS and fly ash in the ratio of 100:0, 75:25, 50:50, 25:75 and later for the best ratio (75:25), GGBS is replaced by ultra-fine GGBS by 7.5, 12 and 20%. Samples were compared with cured at ambient temperature and oven curing. The results showed that mix proportion of 20% replacement of ultra-fine GGBS gave the maximum strength for both oven and ambient curing (76.2 and 91.1 MPa). Even all the durability properties are within the permissible limits.
