  • 例句與用法
  • ( 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
    而與x40 ;比較,減水率、凝結(jié)時(shí)間、保坍性、抗壓強(qiáng)度比等綜合性能還有一定的差距,有待進(jìn)一步的改進(jìn)和研究。從合成pc23一6的工業(yè)性分析: pea23的酷化和pc23一6的共聚的放大試驗(yàn)看,其混凝土試驗(yàn)結(jié)果較為理想,且其合成工藝流程較為簡(jiǎn)單,具備高分子的合成條件:而從經(jīng)濟(jì)性分析, 30 % pc23一6水溶液的原料成本低于fdn ,其性能具有較大的優(yōu)勢(shì),具有廣闊的工業(yè)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
    通過測(cè)定減水劑的水泥凈漿流動(dòng)度及流動(dòng)度損失宏觀反映合成減水劑共聚體pc的性能,研究結(jié)果表明: ( 1 )鏈轉(zhuǎn)移劑是控制共聚物分子量影響共聚體pc性能的主要因素之一,在選擇鏈轉(zhuǎn)移劑zy 、用量為8 aa時(shí)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
    主要內(nèi)容有:本文對(duì)75個(gè)高溫作用后的標(biāo)準(zhǔn)立方體新老混凝土粘結(jié)試件進(jìn)行了劈拉試驗(yàn),溫度從常溫到900c分9個(gè)溫度段,降溫方式分自然冷卻和噴水冷卻兩種。著重考察了溫度、降溫方式、界面粗糙度及界面劑對(duì)新老混凝土粘結(jié)劈拉強(qiáng)度的影響規(guī)律,闡述了高溫后粘結(jié)強(qiáng)度下降的機(jī)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 )粘結(jié)劑本試驗(yàn)采用三種粘結(jié)劑:無粘結(jié)劑、同新混凝土相同水灰比的水泥凈漿、摻10 u型膨脹劑的同新混凝土相同水灰比的水泥凈漿(以下簡(jiǎn)稱水泥膨漿) 。界面劑的厚度一般為2 3mm 。
