摘要: AbstractThis paper examines the short-term resistance ability of two different cementitious systems prepared using silty clay as a major component against 5 wt% sodium sulfate and magnesium solutions. The are clay–portland cement clay-high calcium fly ash (FA) geopolymer. 28-day strength clay-FA geopolymer is up to 1.2 times higher than that clay-cement. results show physical performance when exposed solution better While phase prominent in system, gypsum, ettringite phases present both especially clay-cement system. reduction with duration exposure caused by formation crystallization gypsum (observed scanning electron microscope X-ray diffraction) well decalcification CSH phases. There no change microstructu...
