摘　　要：由于传统砂浆存在着品种单一,性能低下的缺点,已经越来越不能适应实际工程的需要。干混砂浆正在逐渐被推广应用,干混砂浆外加剂的发展是推广干混砂浆的技术关键。阐述了干混砂浆外加剂的种类及其对干混砂浆性能的影响,并分析了外加剂对砂浆的改性机理。The traditional mortar with single variety and inferior performance has not accommodated to demands of actural building project. Dry-mixed mortar is being gradually popularized, and the development of additives for dry-mixed mortar is the crux for promotion of dry-mixed mortar.The species and influence of additives （redispersable polymer powder;cellulose;water-reducing agent;water-retentive admixture;air entraining agent） for dry-mixed mortar is mainly elaborated, and the modified mechanism of additives is analyzed.
