The influences of water binder ratio, superplasticizer and mineral blend on the hydration heat of the binder paste were studied by means of hydration heat experiments. The results show that the hydration heat decreases with decrease of water binder ratio of binder paste. The total hydration heat will not decrease with the addition of superplasticizer which contains retarding composite, however the hydration exothermic process is delayed and the later stage hydration is accelerated.

The influences of water binder ratio, superplasticizer and mineral blend on the hydration heat of the binder paste were studied by means of hydration heat experiments. The results show that the hydration heat decreases with decrease of water binder ratio of binder paste. The total hydration heat will not decrease with the addition of superplasticizer which contains retarding composite, however the hydration exothermic process is delayed and the later stage hydration is accelerated. Mineral blend can markedly reduce the hydration heat and the hydration exothermic rate, and postpone the arrival time of the highest temperature, particularly the double adding and tri adding. The influence of these three factors on hydration heat will counteract the deficiency of high hydration heat at early stage due to high content and high strength cement. In this way, the influence of temperature stress is alleviated and the durability of concrete is enhanced.

研究了水胶比、高效减水剂、矿物掺合料对高性能混凝土中胶结材浆体水化热的影响 .结果表明 :当水胶比降低时 ,胶结材浆体的水化热也随之下降 ;缓凝高效减水剂并不降低总水化热 ,但它推迟水化放热进程 ,加快后期的水化放热速率 ;矿物掺合料的加入可明显降低水化热、水化放热速率 ,推迟达到最高温度的时间 ,尤其是双掺、三掺时降低效果更为显著 .利用这三个因素的作用———减小水化热或延迟水化放热进程 ,可以降低因高性能混凝土水泥用量多及标号高所造成的早期高水化热的程度 ,缓解温差应力的影响 ,提高混凝土的耐久性 .

This paper studied the preparation of flame-retarded polypropylene (PP) having different dosages of halogen and Sb2O3, which were added in the form of PP/Sb2O3 masterbatch modified by acrylic acid (AA). The analysis of the resultant PP with differential scanning calorimetry (DSC) indicates that the flame retardant exerts an obvious heterogeneous nucleation in preparation of the PP and therefore, renders the crystallization temperature of the PP raised. The heterogeneous nucleation of Sb2O3 to PP is more significant...

This paper studied the preparation of flame-retarded polypropylene (PP) having different dosages of halogen and Sb2O3, which were added in the form of PP/Sb2O3 masterbatch modified by acrylic acid (AA). The analysis of the resultant PP with differential scanning calorimetry (DSC) indicates that the flame retardant exerts an obvious heterogeneous nucleation in preparation of the PP and therefore, renders the crystallization temperature of the PP raised. The heterogeneous nucleation of Sb2O3 to PP is more significant than that of decabromodiphenyl oxide (DBDPO). Without the presence of dicumyl peroxide (DCP), a further increase in the crystallization temperature of PP in the retardant composite depends only upon content of the flame retardant. However, in the presence of DCP, the crystallization temperature of the PP does not vary with the increment of AA dosage. The increase of DCP content causes the PP in the flame-retarded composite to degrade seriously and furthermore lowers its crystallization and melting temperatures.

研究了丙烯酸(AA)改性Sb2O3,聚丙烯(PP)母料制备的不同用量卤锑阻燃PP。阻燃PP的差示扫描量热法结果表明,阻燃剂在PP中存在明显的异相成核作用,使PP结晶温度提高,Sb2O3对PP的异相成核作用比十溴二苯醚明显。在无引发剂过氧化二异丙苯(DCP)存在下,AA对阻燃PP中PP结晶温度的影响取决于阻燃剂的用量;在DCP存在下,PP的结晶温度不随AA用量增加而改变。DCP用量增加导致PP严重降解,结晶温度与熔融温度降低。
