Abstract

Cement mortar is the mixture of cement, sand and suitable quantity of water to get optimal strength. Now a days in this world the production of cement is increasing to construct the buildings and structures, that will affect the environment if we generate large scale of cement. The engineers are done lot of studies to develop the mix without cement content, but they found that the binding properties of mix prepared without cement content is less, to increase the strength values without using cement content can be done by adding the chemicals with suitable proportions and different methods which are adopted for curing methods. The main objective of the geopolymer mix is to eliminate the cement content for construction. Generally for preparation of geopolymer mortar we use binding materials as Fly ash, GGBS, metakaolin, etc. in the present research study I selected Geopolymer mortar which is developed with fly ash and GGBS based mixture 80% binder content is used as fly ash and 20% binder is used as GGBS for all the mixes. The experimental results like compressive strength, split tensile strength and durability values are compared by taking mix ratios as 1:1.5, 1:2, 1:2.5, and 1:3 mixes with different molarities of NaOH and Na2SiO3 solutions, for preparation of mixture. I used 8M, 10M, 12M, 14M and 16M molarities. The comparison of results is made different mixes and different molarities for 7 days and 28 days of curing.
