slump-loss

基本解释

On the other hand ,the concrete using SNF has afast slump loss.
新型高效减水剂具有氯化物含量和硫酸钠含量很低的特点。
The result indicates pre-wetted aggregate can improve workability and decrease slump loss due to large water absorption of recycled aggregate.
结果显示，预湿可有效改善再生混凝土工作性以及坍度损失过高的问题；
But now, the research about improvement of mineral admixture on slump loss is mostly limited to its optimizing chemic elements of cement.
但是目前关于矿物掺合料对坍落度损失的改善机理仅主要局限于其对水泥化学组份的优化效应。
Based on molecular design theory of polymer,a kind of low slump loss comb-like polycarboxylate type superplasticizer was synthesized.
应用高分子设计原理,合成了一种低坍损梳形聚羧酸系高效减水剂。
The result shows this low slump loss superplasticizer features in easy action property, high water reducing rate, and good performance of concrete, etc.
结果表明：该产品减水剂具有优良的工作性能、高减水性、混凝土性能等特性。
