岩石相似材料水理性质研究
摘要:以水泥和石膏作为胶结剂，石英砂作为骨料的相似材料在一定配比情况下遇水不会发生崩解，而是产生类似岩石的软化现象。通过不同砂胶比和水膏比的相似材料配比试验，总结了相似材料软化系数和吸水率随砂胶比和水膏比的变化规律，即软化系数随砂胶比的增大而降低，随水膏比的增大而升高，变化范围与原型岩石相似；吸水率随砂胶比的增大而升高，随水膏比的增大而降低，变化范围大于原型岩石。
Abstract:The similar material made by cement, plaster and sand in certain ratio situation did not disintegrate when they met water, whereas they softened like rock. By the similar material proportion test at different sand-binder ratio and cement-plaster ratio, this paper summarized the changing rules of softening coefficient and water-absorption affected by sand-binder ratio and cement-plaster ratio. The softening coefficient of similar material reduced as the sand-binder increasing whereas ascended as the cement-plaster increasing and the variation range was similar with real rock. The water-absorption of similar material ascended as the sand-binder increasing whereas reduced as the cement-plaster increasing and it was larger than the water-absorption of real rock.
