[EN] Cellular concrete is an alternative to conventional concrete as a low-density and high-insulating building material. The eco-cellular concretes (ECCs) based on geopolymer technology have been recently introduced by ...

[EN] In the last decade, herbaceous and agricultural biomass have been used as an alternative energy source. As consequence, large amounts of residual ashes containing potassium (potassium-rich ashes) have been generated. ...

[EN] Alkali-activated binder (AAB) is a new material that is being researched as an alternative to the use of Portland cement due to technical and environmental advantages. However, further studies on the durability and ...

[EN] The use of geopolymers has revolutionized research in the field of construction. Although their carbon footprint is often lower than that of traditional mortars with Portland cement, activators such as sodium silicate ...

[EN] This study presents a new cellular concrete design focused on the energy eco-efficiency and the sustainability concept: geopolymer eco-cellular concrete (GECC). Geopolymer systems made from alkali-activated fluid ...

[EN] Cellular Aerated Concrete (HCT, for its acronym in Spanish) is a Portland cement-based binder, which is added an inorganic reagent, generally aluminum powder. Metal aluminum is oxidized immediately when it comes in ...

[EN] Chemistry is an essential science for understanding and developing construction materials. Specifically, the application of the green chemistry concept to the cement sector may allow the fabrication of new environmentally ...

[ES] El peso propio de las estructuras resulta habitualmente del mismo orden o superior al de las cargas que tienen que soportar, lo que las hace en la mayoría de los casos poco eficientes. La solución radica en la ...

[EN] The use of almond-shell biomass ash (ABA) as an alkali source in one-part blast furnace slag (BFS) mortars activation was investigated for the first time. The chemical composition of ABA revealed high alkalinity ash ...

[EN] Resource recovery from waste is one of the most important ways to implement the socalled circular economy, and the use of alkali activated materials can become an alternative for traditional PC-based materials. These ...
