Development of composite mortars based on lime, blastfurnce slag and fly ash Available to Purchase

Slag and fly ash are the most commonly used industrial materials as a replacement for mortar which helped to reduce CO2 emissions. The activation of fly ash and slag with lime mortars have been studies in this paper. The parameters of the processes studies are: two kind of fly ash (Drax and Didcot), curing water pure and humidity room at 65%, and fly ash to-slag ratio (0/100, 10/90, 20/80, 30/70, 40/60, 50/50, 60/40, 70/30, 80/20, 90/10 and 100/0). The main tests are flexural strength and compressive strength. Six samples were prepared for each percentage for both kinds of fly ash, and then curried for 56 days to be ready for test. The results showed that the influence of water pure curing on the development of strength is higher than the influence of humidity room. The samples cured in water showed higher strength than those cured in the humidity room. At 56 days, the highest compressive strength and flexural strength were obtained for samples having 30% of Didcot.
