neat cement meaning in English
净水泥浆
Examples
- Abstract : based on composite testing of naphthalene superplasticizer and different retarders as well as retarding water reducer , in which the overall amount of admixture is certain , this paper analyzes the influence of these multicomponent admixtures on flowability of neat cement 、 retarding action and development of strength of colloidal mortar . the result shows that compatibilities of different components are different , and composition effects are also different
文摘:在总掺量一定的情况下，就萘磺酸盐高效减水剂与不同缓凝组分、缓凝型减水剂等复合后对水泥净浆流动度、缓凝作用、胶砂强度发展等性能的影响作用进行了试验分析，结果表明各不同组份复合的相容性不同，复合效应也存在差别。 - ( 4 ) the neat cement paste fluidity of copolymer would augment and the cohesiveness of cement would increase along with augmentation of pea dosage , but if the dosage was too big , the dosage of aa would be reduced , so it would reduce the carboxylic content of copolymer , and performance of water reduce would weaken , the dosage of pea23 can not more than 25 % . ( 5 ) the effect of water reduce would increase if the copolymer time increase
而与x40 ;比较，减水率、凝结时间、保坍性、抗压强度比等综合性能还有一定的差距，有待进一步的改进和研究。从合成pc23一6的工业性分析: pea23的酷化和pc23一6的共聚的放大试验看，其混凝土试验结果较为理想，且其合成工艺流程较为简单，具备高分子的合成条件:而从经济性分析， 30 % pc23一6水溶液的原料成本低于fdn ，其性能具有较大的优势，具有广阔的工业化的前景。 - The preparation of chain transfer , the mol percent of pea : aa : mma and the time of combind were systermic investigated . the performance of pc was refledted by the neat cement paste fluidity and fluidity losing . the results indicated : ( 1 ) the preparation of chain transfer was one of most factor of control the molecular weight of copolymer and influence the performance of pc
通过测定减水剂的水泥净浆流动度及流动度损失宏观反映合成减水剂共聚体pc的性能，研究结果表明： ( 1 )链转移剂是控制共聚物分子量影响共聚体pc性能的主要因素之一，在选择链转移剂zy 、用量为8 aa时的作用效果最佳。 - The main content is : splitting tensile experiments were carried out about the standardized cube bonding specimens ( 150x 150x 150mm3 ) of the new - old concrete after high temperature . the temperature is divided into 9 groups from normal atmospheric temperature to 900 , the cooling styles are natural cooling and spraying water cooling ; different interfacial treating methods : brushed with steel - wire brush , man - made chiseling ( not evenly ) , man - made chiseling ( quite evenly ) ; different interfacial agents : no interfacial agent , neat cement paste , cement paste mixed with 10 % expanding agent
主要内容有：本文对75个高温作用后的标准立方体新老混凝土粘结试件进行了劈拉试验，温度从常温到900c分9个温度段，降温方式分自然冷却和喷水冷却两种。着重考察了温度、降温方式、界面粗糙度及界面剂对新老混凝土粘结劈拉强度的影响规律，阐述了高温后粘结强度下降的机理。 - ( 2 ) interfacial agents this experiment adopts three types of interfacial agents : no interfacial agent , neat cement paste which has the same water - cement ratio with the new concrete , cement paste mixed with 10 % expanding agent which has the same ratio with the new concrete ( which is called cement paste mixed with expanding agent for short ) . the thickness of the interfacial agent is 2 ~ 3mm
（ 2 ）粘结剂本试验采用三种粘结剂：无粘结剂、同新混凝土相同水灰比的水泥净浆、掺10 u型膨胀剂的同新混凝土相同水灰比的水泥净浆（以下简称水泥膨浆） 。界面剂的厚度一般为2 3mm 。
