摘　　要：将四种不同配方的复合外加剂(掺加萘系Ⅰ、掺加萘系+氨基磺酸盐Ⅱ、掺加聚羧酸系Ⅲ和掺加氨基磺酸盐Ⅳ复合外加剂)按不同掺量加入到水泥中,比较测出的水泥净浆流动度和水泥砂浆抗折抗压强度数据,选出一种使水泥净浆流动度经时损失比较小、水泥砂浆强度高、压折比较小的方案。结果表明:掺加萘系+氨基磺酸盐Ⅱ复合外加剂是符合道路混凝土工程施工和使用要求的一种复合外加剂优化方案。Added four different compound additives（naphthalene-based Ⅰ ,naphthalene-based and aminosulfonic acid-based Ⅱ ,polycarboxylate Ⅲ and aminosulfonic acid-based Ⅳ）in different dosage respectively into Portland cement, and compared the data of the fresh cement fluidity and the mortar cement flexural strength,compressive strength and selected a scheme which made the loss of the fresh cement fluidity less, higher strength of the mortar cement,lower ratio of compressive and flexural. The results show that naphthalene-based and aminosulfonic acid-based Ⅱ compound additive is the one meets the roadway engineering requirements.
