Advanced progress in recycling municipal and construction solid wastes for manufacturing sustainable construction materials
TL;DR: In this paper, a review of the existing studies on recycling municipal and construction solid waste for the manufacture of geopolymer composites is presented, and the results indicate that although the inclusion of such waste might depress some of the attributes of these composites, proper proportion design and suitable treatment technique could alleviate these detrimental effects and further smooth the recycling progress.

Geopolymers : inorganic polymeric new materials
TL;DR: In the last few years, technological progress has been made in the development of new materials such as "geopolymers" and new techniques, such as ''sol-gel'' as mentioned in this paper, opening up new applications and procedures and transforming ideas that have been taken for granted in inorganic chemistry.

Influence of mineralogy and firing temperature on the porosity of bricks
Giuseppe Cultrone,Eduardo Sebastian,Kerstin Elert,Maria Jose De la Torre,Olga Cazalla,Carlos Navarro +5 more
TL;DR: In this paper, the changes in brick porosity upon firing and its relation to the mineralogical composition are examined, showing that the presence or absence of carbonates strongly influences the porosity development and, therefore, the brick texture and physical-mechanical properties.
