摘要：

This paper report experimental results of several mixes regarding the joint effect of replacement percentage of fly ash by waste glass, sodium hydroxide concentration, activator/binder ratio, the use of two commercial superplasticizers and a biopolymer on the cost and global warming footprint performance of alkali-activated mortars. In the mix compositions the significant impact on the cost of mixtures is concerned to the molarity concentration of NaOH solution, while replacing fly ash by milled glass has no great impact on the total price The minimum values for the normalized cost and GWP to compressive strength were measured about 22 Euro/m(3).MPa and 17 kgCO(2)e/m(3).MPa in the mixture 80FA_10CH_10MG_4M_0.5A/B.
