摘要
本文通过对聚羧酸系高效减水剂在重庆地区混凝土应用的试验及研究,结果表明该产品在减水率、保塑性、强度及抗渗引气性能方面较萘系减水剂具有绝对优势,特别用于配制高强混凝土,可以采用价格低廉的矿粉取代硅灰,取得了更好的技术优势和经济效益。
Through experiment and research on the application of polycarboxylate superplasticizer in ChongQing, the results indicated that polycarboxylate superplasticizer has absolute predominance than normal water-reducers in water-reducing rate, plasticity retain ability, strength, impermeability and air-entraining performance, especial in producing HSC, which may use cheap slag to replace silicon ash to accomplish better technical superiority and the economic efficiency.
