碳化收缩 meaning in English
carbonated shrinkage
Examples
- We research the causes of concrete cracking , develop the high performance anti - cracking additive , optimize the concrete mix and construction techniques , increase the stability of concrete volume by shrinkage compensation , enhance splitting tensile strength , and can meet demand of high workability of fresh concrete . . in the study , a thorough investigation of this problem is made from all points of view , with the aid of various modern measurement & testing technology and different theories & methods in surface physical chemistry , structural chemistry , solid - state chemistry , composite materials , fracture mechanics , etc . our research results have shown that the various shrinkage of concrete cause concrete cracking in building engineering , such as autogenous shrinkage , dry shrinkage , temperature shrinkage , plastic shrinkage , carbonized shrinkage , etc
目前，解决混凝土开裂的方法是综合的，我们调查研究了混凝土开裂的原因，开发研制了高性能抗裂外加剂，优化混凝土的设计和施工方法，并通过补偿收缩达到混凝土体积稳定，提高抗裂强度，满足混凝土拌和物高工作性能的要求。本研究采用多种测试技术，应用表面物理化学、结构化学、固体化学、复合材料学、断裂力学等多学科的理论与方法，从不同的角度进行深入的研究和探讨。通过调查研究建筑工程中出现的混凝土开裂、渗漏问题，发现混凝土在非荷载作用下开裂主要是由混凝土的自收缩、干燥收缩、温度收缩、塑性收缩、碳化收缩等各种收缩变形引起的。 - Tensile stress will accelerate the carbonation of paste and mortar , which can be explained by the reason that shrinkage of carbonation is confined by tensile stress , and the function x = c0eantb can describe this process . carbonation can lower the total porosity and lessen the aperture in the cement paste
外部弯曲应力会加速水泥石和水泥砂浆的碳化过程，这可能与受拉区域碳化收缩受到限制有关：弯曲应力作用下水泥石和水泥砂浆的碳化动力学过程可用式x = c _ 0e ~ ( an ) t ~ b描述。
