【摘要】 本文研究了沸石在沸石岩水泥和沸石岩钢渣水泥中作为活性混合材的水化作用机理,得到下列结论: 1.水泥石中沸石作用是阴阳离子结合的酸碱反应,而不是离子交换。 2.化学反应的实质是沸石和“有效石灰”之间的反应。这个反应机理可称为:“多阶段化学反应模式”。第一阶段是脱铝;第二阶段分解氧化硅;第三阶段化合氧化钙。 3.沸石岩作为水泥混合材的活性比同化学成分的沸石岩玻璃的活性好。 4.沸石岩的最佳掺量是15～20％,最大掺量是45％,超过此值,沸石岩水泥的强度大幅度下降。 5.由于沸石和“有效石灰”间的反应是不完全的,所以掺入水泥中的某些沸石岩仍残留下来。更多还原

【Abstract】 1. The nature of the reaction of zeolite in the hydration of cement has been found to bethat of acid and alkali reaction rather than cxchange of ions. 2. The process of reaction is referred to be the initial detachment of alumina from theframework of zeolite in saturated lime solution followed by libration of active silica fromthe remaint of zeolite.The active silica then reacts with Ca（OH）₂ to form hydrated calciumsilicate. 3.As an admixture of cement, zeolite is more active in crystalline state than its glass ofsame chemical composition. 4.The optimum content of zeolite in the blended cement has been determined to be 15～20%, the maxium content being 45%. 5.A portion of zeolite has been found to remain in the hydrating cement which may beconceived by the fact that the reaction of zeolite with Ca（OH）₂ seldom proceeds to complc-tion.更多还原
