TL;DR: In this article, a binary geopolymer system composed of metakaolin (MK), waste red brick (WRB) powder and sodium silicate solution as an alkaline activator was investigated.

TL;DR: In this article, the authors used red-clay ceramic powders and a varying amount of Na2O/SiO2 activator to synthesize a geopolymer from metakaolin, fly ash, or blast furnace slag.

TL;DR: In this article, the effect of high temperatures of up to 1200°C and rehydration on the mechanical properties, microstructure and phase composition of blended cement pastes prepared from Portland cement (PC), granulated blast furnace slag (GBFS), high-temperature fly ash (FA) and ground limestone (GL).

TL;DR: In this article, a characterization of non-hydrophobized lightweight renders designed at once for repair and thermal insulation purposes was performed, where silica sand was partially or fully replaced with expanded perlite of the similar grain size distribution, whereas the workability of fresh renders was maintained on the same level.

TL;DR: In this paper, the flexural and compressive strength of natural zeolite-blended cement pastes were investigated, while the leachability of the heavy metals was determined.
