| 中文摘要: |
| 以萘系减水剂和脂肪族减水剂复配获得高效减水剂，并通过添加葡萄糖酸钠改善复合减水剂与水泥混凝土的适应性。结果表明：掺有粉煤灰的P·O42.5R水泥与复合减水剂的相容性不好，加入缓凝剂葡萄糖酸钠后，复合减水剂与水泥的相容性提高。 |
| 英文摘要: |
| A high efficiency water reducing agent was prepared by naphthalene and aliphatic water reducer, and the compatibility between the composite reducer and concrete was improved by adding sodium gluconate. The results show that the compatibility of P·O 42.5R cement and the composite water reducer is bad, and when sodium gluconate is added, the compatibility improved. |
