摘　　要：将三种不同配方的复合外加剂:掺加萘系(Ⅰ)、掺加氨基磺酸盐(Ⅱ)和萘系+氨基磺酸盐(Ⅲ)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,选出一种使水泥净浆流动度经时损失较小、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(Ⅲ)复合外加剂是符合公路工程要求的一种优化方案。By mixing three different formulas of compound additives and adding naphthalene - based （Ⅰ）, aminosulfonie acid - based （Ⅱ） , and naphthalene - based and aminosulfonic acid - based （Ⅲ） into cement in different dosages, the fresh cement fluidity and the flexural strength and compressive strength of mortar cement are measured to choose an optinal additive. The results show that naphthalene - based and aminosulfonic acid - based （ II1 ） compound additive is the optimal additive, which can make the fresh cement fluidity have less loss and the mortar cement have a high strength and a low ratio of compressive to flexural, and meets with highroad engineering requirements.
