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...

A type of heat-curing phosphate binder was proposed, and orthogonal experiments based on the tensile strength sand samples determined that optimal composition phosphoric acid: water: aluminum hydroxide: magnesium oxide: boric acid = 300: 70: 60: 9: 8. Adding 10% polyvinyl alcohol (PVA) solution during mixture process can significantly improve 24 h samples. When adding 30 g 8 PVA solution, initi...

Abstract By taking advantage of a stability criterion established recently, the critical temperature T c is reckoned with help microscopic parameters, characterising normal and superconducting electrons, namely independent-electron band structure repulsive two-electron force. The emphasis laid on sharp dependence upon electron concentration inter-electron coupling, which might offer practical r...
