This paper explores hybrid alkaline cement composites with high content over 50%. Calcium (Ca) accelerates the strength development and improves compressive of geopolymer. However, mixing proportion Ca in geopolymer has been limited because significantly decreases flow fresh study resolves decline issue by a part initial water before adding it into metakaolin-based geopolymer, which is named (H...

Amorphous silica and alumina of metakaolin are used to adjust the bulk composition of black (BSS) and white (WSS) steel slag to prepare alkali-activated (AAS) mortars consolidated at room temperature. The mix-design also includes also the addition of semi-crystalline matrix of river sand to the metakaolin/steel powders. The results showed that high strength of the steel slag/metakaolin mortars ...

The preparation and characterization of composite materials based on geopolymers obtained from fly ash and epoxy resins are reported for the first time. These materials have been prepared through a synthetic method based on the concurrent reticulation of the organic and inorganic components that allows the formation of hydrogen bonding between the phases, ensuring a very high compatibility betw...

This study focuses on calcined kaolin, commercial sodium silicate, and Amazonian bamboo to make geopolymer. The durability of geopolymer matrix (GP) fiber composite (GPBF) materials was analyzed by studying the resistance exposure sulfuric hydrochloric acids at concentrations from 0 15 wt%, testing two different geometry samples. microstructure raw investigated X-ray fluorescence scanning elect...
