dc.description.abstractThe utilization of Portland cement in concrete production is increasing. At the same time, the performance of Portland cement poses different kind of challenges such as high mechanical strength and good durability performance. Thus, geopolymeric material has been incorporated to overcome these technical challenges. The experimental investigation was conducted to characterize physical and chemical properties of hybrid geopolymer binder material which consist of ground granulated blast furnace slag (GGBS) and pulverised fuel ash (PFA) with the activation of Portland limestone cement (PLC) in different aspect such mechanical strength, durability performance and dimensional stability. By the process inter-grinding of 2 hours duration, it shows that with the inclusion of 50-60% of PLC in the production of mortar, the mechanical and durability performance of mortar mix was found to be exceptionally better as compared to both control mortar mixes produced using 100% PLC and 100% of geopolymeric binder material. The hybrid matrix of cement and geopolymer with the ratio of 60% PLC, 32% of GGBS and 8% of PFA shows improvement of 19% at 7 days and up to 34% at 90 days of increment in compressive strength as compared to control mix with only PLC.en_US
