Examples
- Unit compressive stress
单位抗压应力 - Standard test method for in situ compressive stress within solid unit masonry estimated using flatjack measurements
用液压千斤顶现场测量实心砌块抗压应力的标准试验方法 - 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。
