摘　　要：研究了萘系减水剂、糖对不同水泥的适应性。研究了同一掺量的减水剂与不同糖复合时,糖对净浆流动度、砂浆强度的影响。研究表明:掺入不同的糖,水泥净浆流动度有不同程度的提高,并有效降低了水泥净浆的流动度损失;掺入适宜的糖能提高砂浆28 d的强度。该项研究为今后的实际工程应用提供了可靠的技术依据。Studied the adaptability of chennai superlasticizer and sugar to different cement, about the impact on the fluidity and drying shrink- age of cement paste and mortar strength of different sugar with the same dosage of agent.The study investigated that： with different sugar, the flu- idity of the cement paste will be increased, the shrinkage of paste will be reduced; with a suitable content of sugar, mortar strength of 28 days in- creased.The study provided a reliable technical basis for future practical engineering applications.
