水化水泥 meaning in English
hydrated cement
Examples
- Test method for calcium sulfate in hydrated cement mortar
水化水泥胶砂中硫酸钙含量的测定方法 - Superplasticizer mainly absorbs on the cement hydrates covering the surface of cement particles instead of on the surface of unhydrated particles
超塑化剂主要是大量吸附在水泥颗粒表面的水化产物上而不是吸附在未水化水泥颗粒表面。 - With the very low water to cement ratio , rpc has ultra - high strength high ductility and low permeability . in this paper , the compressive strength of rpc can reach to a high point with the number approximately 135mpa . as illustrated from the study results , we can approve some fundamental conclusions : there are big effects on rpc with deferent kinds and properties of raw materials and deferent curing conditions ; stress - strain curve shows the process of destroy with rpc samples ; x - ray diffraction analysis indicates that heat treatment at temperatures 90 accelerate the hydration of rpc sharply , therefore , mechanical and microstructural properties of rpc are highly dependent on heat treatment ; it is believed that rpc materials have excellent resistance to chloride permeability ; during the heat treatment , the shrinkage of rpc developed quickly because of chemical reactions ; the rpc with slag mostly has the advantage of rpc without slag about resistance to solutions corrosion
研究结果表明：通过对rpc各组分掺量变化的研究，可以找到rpc的最优配合比；试件成型后的热养护制度对rpc的性能影响巨大； rpc的抗压应力?应变曲线可以反映出试件受破坏时微裂纹的扩展情况，刚纤维的掺入可以大幅改善rpc的韧性； rpc在成型后存在较大的收缩，而其中的化学收缩要远远大于干燥收缩； rpc具有很强的抗氯离子渗透性能，浆体的密实度很高；通过x射线衍射实验，可以发现rpc的胶凝体中ch晶体已经几乎不存在，胶凝体主要由c - s - h凝胶和未水化水泥颗粒组成；在抗溶液侵蚀的实验中，掺矿渣rpc的抗溶液侵蚀性能在绝大多数情况下要好于不掺矿渣试件，酸、碱溶液和浙江工业大学硕士学位论文摘要一些盐溶液都会对rpc的结构产生侵蚀作用，但是机理各有不同。
