【摘要】 固相反应合成钙矾石龙世宗，邬燕蓉，王俊春（武汉工业大学）钙矾石的形成方式对其膨胀和力学性能有重大影响。目前关于钙矾石形成机理归纳起来主要有两种：１．局部化学反应机理；２。溶解沉淀结晶机理。Ｌａｆｕｍａ￣［１］提出当硫酸盐离子与硬化水泥浆中的铝酸盐固相...更多还原

【Abstract】 Mix propertioning was made with powdery chemical agents such as Al₂（SO₄）₃·18H₂O,KAl（SO₄）₂· 12H₂O,Al （OH）₃,CaSO₄·2H₂O,Ca（OH）₂ and hydrated calcium aluminate in accordance withthe chemical composition of ettringite.The seven samples were homogeneously mixed,ground and properlycured.After a proper time,XRD and DTA were used to investigate the samples,Ettringite was observed inevery sample.The result shows that ettringite can be formed by solid-solid reaction.更多还原
