Abstract This work aimed to evaluate the role of addition blast furnace slag for formation reaction products and strength development volcanic ash-based phosphate geopolymer. Volcanic ash was replaced by 4 6 wt% ground granulated accelerate kinetics. Then, influence boric acid controlling setting kinetics reactions also evaluated. The results demonstrated that competition between dissolution as...

To evaluate the effects of industrial by-products materials on the performance of porous concrete for plant growth, this study investigated the physical, strength, and freeze/thaw resistances of porous concrete for plant growth, prepared by replacing cement with blast furnace slag powder at 60% by weight, and replacing natural stone aggregates with coarse blast furnace slag aggregates at rates ...

Alkali activated material has recently attracted great attention as an environmentally friendly building material. Generally, it exhibits higher mechanical properties and better durability when compared with Portland cement based materials. In this article, mixed alkali activated systems consisting of N-A-S-H and C-A-S-H hydrated gels were produced, using metakaolin as a dominated starting mate...

Abstract The purpose of this study was to evaluate the possibility using ground waste-expanded perlite (WP) as a sustainable replacement for granulated blast-furnace slag (GGBFS) precursor in alkali-activated systems. nature and amount hydration products, microstructure, compressive strength development were investigated mixtures where GGBFS substituted with 10, 20 40% by weight WP activated tw...

This paper studies the influence of assembly unit expansive agents (CaO and calcium sulphoaluminate) on limited free compressive strengths, expansion rate, carbonation resistance, chloride ion penetration resistance corrosion reinforcement concrete. The dosages agent were 0%, 3%, 6%, 9%, 12% by total amount cementitious materials. Two kinds mineral admixture (blast furnace slag fly ash) applied...
