Flow Performance Of Hybrid Cement Based Mortars

This paper reports experimental results of 32 hybrid cement mixes regarding the joint effect of sodium hydroxide concentration, the use of a commercial superplasticizer and a biopolymer on the flow and compressive strength performance. The results show that the use of commercial admixtures led to a slightly increase in the flow of mortars with lower sodium hydroxide concentration. A mixture based on 80% fly ash, 10% calcium hydroxide and 10% waste glass showed the highest compressive strength. A compressive strength decrease was noticed concerning the use of the two admixtures that can due to the fact that those admixtures are not stable on high basic media.
