admixture dosage 中文意思是什麼
admixture dosage
解釋
外摻劑量-
The results of research on the workability of hbc concrete show that hbc concrete, when compared with opc concrete, has excellent compatibility with superplasticizer, in terms of better initial fluidity, less slump loss, definite saturation point and less dosage at saturation point. in addition, good mineral admixture such as i class fly ash can obviously improve the workability of hbc concrete. moreover, hbc concrete exhibits more excellent workability under the condition of low w / c ratio, which indicates hbc is more suitable for making super high strength concrete whose w / c ratio is very low
對高貝利特水泥高性能混凝土工作性能的研究結果表明，高貝利特水泥與高效減水劑具有良好的適應性，表現為初始流動度較大，經時損失較小，具有明顯的飽和點且飽和點摻量較小；此外，優質的礦物摻和料如一級粉煤灰能明顯改善hbc混凝土的工作性能；更為突出的是hbc混凝土在低水膠比的情況下表現出更為優異的工作性，這一特性預示著高貝利特水泥更適宜配製水膠比很低的超高強混凝土。 -
By research these, wocan know : 1 ) in different fineness cement, the dosage of mineral admixture improve the fluidity of cement mortar. when the dosage reach 50 %, the effect of mineral on fluidity can be better than the changing fineness of cement. 2 ) to different fineness and dosage mineral, the improve of mineral can improve the compatibility
通過研究結果發現： 1 ）對于不同細度的水泥，當礦物的摻量達到50以後，礦物摻合料對水泥膠砂流動度的影響顯著，而水泥細度的變化對相容性的影響較小。 -
By research the effect of mineral mixture on cement and admixture, we can improve it ' s utility in cement concrete. in this article we use the slag and fly ash as research object. we study the effect of the mineral " s dosage on the compability of different fineness cement and admixture, the effect of mineral fineness to the compatibility of cement and admixture. wo also research the effect of mineral to different cement and admixture in chongqing. by the study, we continue changing the character of mineral to improve it ' s effect to compatibility. slag and fly ash mix each other can have better character to the compatibility of cement and admixture. changing slag by admixture and gypsm also can improve it ' s compatibility to cement and admixture
礦物摻合料對水泥與不同摻量的外加劑之間的相容性影響。並結合重慶市現有的資源，研究了礦物摻合料對重慶地區不同廠家的水泥與外加劑的相容性影響。進而對礦物料的缺陷進行改善，採用礦渣與粉煤灰混摻，膨脹劑與礦渣混摻，礦渣與石膏，礦渣與外加劑混磨，優化礦物摻合料，更好的促使其在重慶市水泥混凝土中的應用。 -
Two - addition technique of flying ash and silica fume can meliorate durability of concrete ; air - entraining admixture possesses anti - freezing, descending ice point, and improving workability, and thereof it should be used in concrete. but controlling its dosage is very important to avoid strength loss
發現粉煤灰和硅灰的雙摻技術能夠顯著改善混凝土的耐久性能，引氣劑具備防凍抗凍、抗滲及提高負溫混凝土工作性的優點，在負溫混凝土中應該加大使用范圍，但必須控制其摻量，確保強度損失較小。 -
The results indicate that less dosage of water, clay, bentonite and larger dosage of cement, and mixing coal ash and admixture can increase compressive strength of plastic concrete
結果表明，減小水膠比及黏土和膨潤土的用量，增加水泥用量，摻加粉煤灰和外加劑，均可提高塑性混凝土的抗壓強度。
