pumping admixture 中文意思是什麼
-
The research result indicated that on the condition of the same mortar fluidity, the preventing effects of mineral and superplasticizer compounded on aar are better than that of mineral used singly, the preventing effects of mineral admixture and entraining agent compounded are better than that of mineral admixtures used singly, the preventing effects of mineral and superplasticizer and entraining agent compounded are lower than that of mineral admixture and entraining agent compounded. the research achievement has some guiding sense on the recognition of aar prevention in pumping hpc and the researches of test methods for determining the alkali reactivity of aggregate used in hpc
研究結果表明：在相同砂漿流動度條件下，減水劑與礦物摻合料復合使用對堿?骨料反應的抑制作用大於礦物摻合料單獨使用的抑制作用；引氣劑與礦物摻合料復合使用對堿?骨料反應的抑制作用優于礦物摻合料單獨使用的抑制作用；減水劑、引氣劑與礦物摻合料三元復合使用對堿?骨料反應的抑制作用小於引氣劑與礦物摻合料二元復合使用的抑制作用。 -
The author excogitated a kind of appropriative mud jacking material which is made up of cement, sand, fly ash, admixture and water. this material which was developed on the basis of large amount of tests has the proprieties of good self - flowing density, high earlier strength, non - segregation, non - weepage and non - contractility. especially, the author aim at dealing with pumping mud and earlier maintained developed a kind of high flow grade material which can meet the requirement of mud jacking
本文研製了專用壓漿材料，採用水泥、砂、粉煤灰、外加劑和水混拌而成，通過大量實驗配製出的漿液具有自流淌密實性好、早期強度高、無離析、無泌水、無收縮的性能，特別是針對路面唧泥處理或預防性養護，板底脫空量較小，研製出高流動度材料，能滿足壓漿施工的需要。
