采用3种保水剂羟丙基甲基纤维素醚、膨润土、羧甲基纤维素钠掺入普通水泥砂浆中，探究3种保水剂对新拌砂浆抗压折强度、和易性、保水性等性能的影响。试验数据分析得：掺羟丙基甲基纤维素醚、羧甲基纤维素钠这两种保水剂的砂浆早期强度发展比较缓慢，掺膨润土的砂浆早期强度发展较快；羟丙基甲基纤维素醚、羧甲基纤维素钠使砂浆的抗压强度降低，抗折强度提高；3种保水剂的保水能力相当，掺入量较多时，羟丙基甲基纤维素醚的保水能力更强。

Experiments were using three aquasorb,hydroxypropyl methyl cellulose,bentonites,sodium carboxymethyl cellulose incorpo-ration of ordinary cement mortar,explore the impact of three aquasorb discount on fresh mortar compressive strength,workability,water retention and other properties. Analysis of experimental data obtaine mixed with hydroxypropyl methyl cellulose and sodium carboxym-ethyl cellulose mortar early strength relatively slow,mortar mixed with betonies rapid early strength development. Hydroxypropyl methyl cellulose and sodium carboxymethyl cellulose can reduce the compressive strength of mortar,and increase flexural strength. These three kinds of water-holding capacity is quite aquasorb,incorporation of more,the water retention capacity of hydroxypropyl methylcellulose stronger.
