The present paper investigated the process of the slag wool fabrication using high temperature blast furnace (BF) slag modified by coal ash (CA). The liquidus temperature and viscosity of the slag system with different mass ratios of BF slag and CA were measured through an inner cylinder rotation method. The approximate mass ratio used to fabricate the slag wool was therefore determined and sla...

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...

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 (...

The aim of this study is to compare the mechanical and physical properties different geopolymer mortars made with granulated blast furnace slag as a source material, NaOH (8 M) activating solution, three types fine aggregates (air-cooled slag, biomass bottom ashes, silica sand). samples were an aggregate/geopolymer ratio 3/1, (density mercury intrusion porosimetry), (compressive flexural streng...
