TL;DR: In this paper, the properties and microstructure of alkali-activated cement pastes and mortars produced using red clay brick waste were investigated, and it was shown that the type and concentration of acid activator can be optimised to produce mortar samples with compressive strengths up to 50MPa after curing for 7 days at 65°C.

TL;DR: In this paper, the sugar cane bagasse ashes (SCBA) have been chemically, physically and mineralogically characterized, in order to evaluate the possibility of their use as a cement-replacing material in the concrete industry.

TL;DR: The influence of sewage sludge ash (SSA) on workability of cement mortars has been studied and only significant differences in workability for mortars prepared with high water volumes or with the presence of superplasticizer were observed.

TL;DR: In this paper, the influence of water/binder ratio and the replacement percentage of FC3R on the pozzolanic reaction were investigated by means of thermogravimetry (TG) of cured FC 3R-Portland cement pastes.

TL;DR: In this article, the effect of the use of an alternative activator based on nanosilica/MOH (M = K + or Na + ) blended solutions on the performance of alkali-activated fly ash binders was assessed.
