alkali aggregate reaction 中文意思是什麼
alkali aggregate reaction
解釋
骨料堿化反應-
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
水電行業有句「無壩不裂」的俗話，產生裂縫的原因主要有「堿集料反應」造成的破壞性膨脹，水泥水化過程中放出的熱量出現的混凝土內外溫度梯度和水泥石硬化後由於後期降溫發生的體積收縮等造成。 -
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
本文從防止「堿集料反應」 、降低水泥水化放熱峰、控制混凝土內部絕熱溫升和利用mgo微膨脹補償水泥石硬化後期產生的收縮等方面進行研究與探討。 -
The liquid - gas method is improved based on the above methods, overcoming the defects of gbj82 - 85. using the liquid - gas method, permeability condition of concrete can be tested and indicated quickly, efficiently, and the influences on concrete of alkali - aggregate reaction, sulfate attack, carbonization, steel rust, freeze and thaw can be inflected indirectly. it is significant on the research and monitor on the durability of concrete
溶液氣壓法是在上述方法之上進行改進提高的，克服了國標gbj82 - 85方法中的許多不足之處，能夠多角度、快速、高效、真實、準確地再現現場混凝土的滲透情況，並且能間接反映堿-骨料反應、鋼筋銹蝕、碳化、硫酸鹽侵蝕及凍融破壞的影響，對混凝土耐久性的監測與研究具有重要意義。 -
Diagnosis and prevention of alkali - aggregate reaction
堿集料反應的診斷與防治 -
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
實際工程中的混凝土結構，因侵蝕性介質的存在而使非力學破壞行為無處不在，這些非力學破壞行為包括堿集料反應、硫酸鹽侵蝕、碳化、鋼筋銹蝕、凍融等，單一的破壞形式或多形式的復合破壞作用對混凝土結構性能及耐久性能均有著較為嚴重的影響，在很大程度上縮短了建築物的服役年限，而這些非力學破壞在很大程度上取決于其滲透性，所以測試混凝土滲透性能是研究判斷混凝土耐久性的常規必測項目。 -
At the same time fly ash and silica fume also can repress the anti - sulfate attack and the alkali - aggregate reaction ; in addition, the relation between air - entraining admi xture, cementitious materials quantity with freezing - thaw property of concrete were studied ; and according to the different affecting factors the durable life of concrete was estimated
同時粉煤灰、硅灰還可以抑制硫酸鹽侵蝕及堿集料反應；此外，分析了混凝土中含氣量、膠凝材總量等與混凝土抗凍性的關系。並且，根據相應影響因素對混凝土耐久性壽命進行了預測。 -
Contrete - reactivity of a concrete formula with regard to the alkali - aggregate reaction - performance test
混凝土.有關堿-集料反應的混凝土配方的反應性.性能試驗 -
Concrete alkali - aggregate reaction can be great damage to the concrete, which is called the cancer of content
摘要混凝土堿骨料反應對混凝土的結構會產生相當大的危害，被稱之為混凝土的癌癥。
