摘　　要：采用蜜胺脂与糖蜜、糖钙复合配制成高效减水剂,它们对水泥净浆、砂浆有较好的减水效果,流动度经时损失小。这两种复配型减水剂能明显改善混凝土的和易性,降低坍落度损失和提高混凝土抗压强度。通过与单掺蜜胺脂、FDN减水剂的试样比较,这两种复配型减水剂表现出较好的综合性能。The two kinds of compound high efficiency water-reducing agent are made of melamine added molasses or calcium of molasses. They have been studied on the physical properties of cement paste and cement mortars namely setting time, flow characteristics and compressive strength. They can remark ably improve the workability, reduce the gradual loss of lump and improve the compressive strength of concrete. Compare with the specimen added one kind of water-reducing agent such as melamine ,FDN, they have better general properties.
