bentonite cement 中文意思是什麼
bentonite cement
解釋
膠質水泥-
The grouting liquid with this stability agent has many advantages such as the good volume stability, low dialysis ratio, high strength of cement rock less dry - shrink and convenient construction etc. when the water - cement ratio is 0. 6 or 0. 8, the 28d strength of cement - rock is 210 % and 179 % of the bentonite cement - rock under standard maintain
該穩定劑配製的水泥漿具有體積穩定性好、不析水、結石強度高、不幹縮、施工方便等優點。如水灰比0 . 6 、 0 . 8時，標準養護條件下28d強度分別較膨潤土水泥漿結石提高100和80以上， 20水中養護28d強度則提高30左右。 -
In this work develop is a new type of macromolecule polymer stability agent mac for the gin grouting method. it has strength of cement rock, low drying shrinkage, good groutability and construction convenience over the bentonite stabilizing agent
本課題針對gin灌漿法研製了新型聚合物mac穩定劑，該穩定劑較膨潤土穩定劑配製的水泥漿具有諸多優點，可成為配製高性能穩定水泥漿液的重要技術措施。 -
The surplus barite, bentonite and cement have to trans - fered to the supply boat
反多餘的重晶石，粘土粉和水泥運到拖輪上。 -
The 28d strength is about 134 % and 129 % that of the bentonite cement - rock under maintain in 20 water
該聚合物穩定劑的研製為提高灌漿品質和耐久可靠性開啟了新途徑。 -
The influence of retarder on the seaing time and ultimate strength of gypsum plaster was investigated in this paper. the experimental results indicate that the effect of single retarder, such as citric acid, is inferior to that of composite retarder which was made of blending citric acid with a few portland cement ( about 0. 5 ?, by weight ). the effect of different water - retention agents, such as polyvinyl alcohol ( pva ), carboxymethyl cellulose ( cmc ), and na - bentonite, etc., was also studied, and the results demonstrate that by means of adding organic and inorganic water - retention agent simultaneously the water - retention of plastering slurry can obviously be improved. the optimal mix proportion of gypsum plaster suitable to finish coat of walls and ceilings of buildings has been got by use of factorial experiment with orthogonal array accounting for interactions between factors each other
研究了分別以檸檬酸、檸檬酸與普通硅酸鹽水泥復合物作緩凝劑，調節粉刷石膏的凝結時間，並對比2種緩凝體系對石膏抗折、抗壓強度的影響.比較不同保水劑（聚乙烯醇、羧甲基纖維素）以及相同量的保水劑在不同工藝流程下保水效果上的區別.探索了有機保水劑和無機保水劑對粉刷石膏的保水性的影響.結果表明，檸檬酸與普通硅酸鹽水泥的復合緩凝劑比單純的檸檬酸更能有效地延緩建築石膏的凝結，同時建築石膏的抗折、抗壓強度降低幅度減小 -
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。
