Vipulanandan p–q model to predict the effect of pressurised water on the strengths of gypsum rock in Kurdistan Region, Iraq

In this study, the effects of soaking time and confining water pressure on the compressive and flexural strengths of rock due to the dissolution of gypsum content in rock samples with 96% gypsum (CaSO 4 ·2H 2 O) content collected from northern Iraq (Kurdistan Region) were investigated. Experiments on compressive strength and flexural strength were performed on gypsum rock samples in normal and pre-saturated conditions. The pre-saturated samples...
