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 properties and microstructure of alkali-activated cement pastes and mortars produced from ceramic waste materials of various origins were investigated, and the compressive strength of the developed mortars ranged between 22 and 41MPa after 7 days of curing at 65°C, depending on the sodium concentration and the water/binder ratio.

TL;DR: In this paper, the effect of fly ash and the hemihydrate form of calcium sulfate on the properties of CSAC was studied and the results suggest that the use of Fly Ash in the presence of anhydrite accelerates the formation of a strong ettringite-rich matrix that firmly accommodated unreacted fly ash particles, both synergistically contributing to a dense microstructure.

TL;DR: In this article, the Spanish Ministry of Science and Innovation (MOSI) and FEDER funded Project GEOCEDEM BIA 2011-26947 were used to support this study.

TL;DR: In this paper, the authors investigated alkali-activated mortars with high ceramic waste contents and found that the mechanical properties of these mortars varied with the type of aggregate used to obtain a binding matrix.
