| 摘 要： | 实际工程中通常通过外加剂过掺来解决混凝土运输过程中的塌落度损失,但外加剂过掺会对混凝土的早期性能和后期的耐久性能产生很大的影响,针对该问题选用两种实际中常用的高效减水剂进行实验。实验发现,适当掺量的减水剂对水泥性能有益,但外加剂过掺对水泥净浆的流动性能、抗压抗折强度以及收缩产生很大的负面影响。

| Abstract: | The strength and shrinkage properties of mortars with different waterreducer were studied.The results indicated that the saturation point was the best dosage of water-reducer,at which it not only helped to reach highest paste fluidity with minimum water-reducer dosage,but also reached the highest mortar strength and comparatively lower shrinkage rate. |

| Keywords: | water-reducer saturation point strength shrinkage |
