碱集料反应 meaning in Chinese
alkali-aggregate reaction
alkaline-aggregate reaction
Examples
- Diagnosis and prevention of alkali - aggregate reaction
碱集料反应的诊断与防治 - Influence of electrochemical desalination on aar of concrete
电化学脱盐对混凝土碱集料反应的影响 - The research of this text is about stopping " alkali - aggregate reaction " , reducing concretes exothermic peak , controling the internal concrete adiabatic storage and using the microexpansivity of magnesia to make up the shrinkage production in the later harden
本文从防止“碱集料反应” 、降低水泥水化放热峰、控制混凝土内部绝热温升和利用mgo微膨胀补偿水泥石硬化后期产生的收缩等方面进行研究与探讨。 - For concrete structure in the practical engineering , the non - mechanics damages , such as alkali - aggregate reaction , sulfate attack , carbonization , steel rust , freeze and thaw , and so on , are unavoidable due to the exist of erosive media . the deterioration form of mono or multi - factor influences on the concrete property of construction and durability greatly , and shortens the service life of the concrete to a large extent . permeability of concrete is the most important factor for these non - mechanics damages , so the permeability test of concrete is the normal and required item to study the durability of concrete
实际工程中的混凝土结构，因侵蚀性介质的存在而使非力学破坏行为无处不在，这些非力学破坏行为包括碱集料反应、硫酸盐侵蚀、碳化、钢筋锈蚀、冻融等，单一的破坏形式或多形式的复合破坏作用对混凝土结构性能及耐久性能均有着较为严重的影响，在很大程度上缩短了建筑物的服役年限，而这些非力学破坏在很大程度上取决于其渗透性，所以测试混凝土渗透性能是研究判断混凝土耐久性的常规必测项目。 - There is an old saying in our field - " no dam is not crackable " . the crack is mainly because of the bad dilation after " alkali - aggregate reaction " , the temperature traverse inside and outside the concrete with the happening of heat evolution and the shrink of volume due to the cooling of concrete
水电行业有句“无坝不裂”的俗话，产生裂缝的原因主要有“碱集料反应”造成的破坏性膨胀，水泥水化过程中放出的热量出现的混凝土内外温度梯度和水泥石硬化后由于后期降温发生的体积收缩等造成。
