Geopolymers are a new type of environmentally friendly cement-based material with serious drying shrinkage problems. In order to overcome this problem and improve the engineering performance durability geopolymers, in study we added 0%, 0.3%, 0.5%, 0.7%, 0.9% polymer materials, namely, polyacrylamide, sodium polyacrylate, tetraborate, respectively, geopolymers reduce their degree shrinkage. We ...

Microstructural and mechanical properties of alkali activated binders based on blends of Colombian granulated blast furnace slag (GBFS) and fly ash (FA) were investigated. The synthesis of alkali activated binders was conducted at 85 °C for 24 h with different slag/fly ash ratios (100:0, 80:20, 60:40, 40:60, 20:80, and 0:100). Mineralogical and microstructural characterization was carried out b...

There has been a significant movement in the past decades to develop alternative sustainable building material such as geopolymer cement/concrete control CO2 emission. Industrial waste contains pozzolanic minerals that fulfil requirements alumino-silicate based geopolymer. For example, industrial red mud, fly ash, GBFS/GGBS (granulated blast furnace slag/ground granulated slag), rice husk ash (...
