In the last few decades, concrete industry has been massively expanded with adoption of various kinds binding materials. As a substitute to cement and in an effort relieve ecofriendly difficulties linked creation, utilization industrial waste as cementitious material can sharply reduce amount trash disposed lakes landfills. With respect mechanical properties, durability thermal behavior, ground...

The main objective of this research was to investigate the influence curing temperature on phase transformation, mechanical properties, and microstructure as-cured sintered kaolin-ground granulated blast furnace slag (GGBS) geopolymer. varied, giving four different conditions; namely: Room temperature, 40, 60, 80 °C. kaolin-GGBS geopolymer prepared, with a mixture NaOH (8 M) sodium silicate. sa...

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...

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...

Abstract Partly replacing Portland cement (PC) with lower carbon footprint cementitious materials such as ground granulated blast furnace slag (slag) is considered a practical method for reducing CO 2 emissions in the concrete industry. To mitigate slow reactivity of system and enhance early-age strength, addition chemical activator solution. However, effect on creep behaviour slag-blended conc...
