| 摘 要： | 从自密实混凝土自身特性出发,研究内掺SAP的方法,以及SAP对于自密实混凝土基本性能的影响。试验发现,在标准条件下,掺入SAP会延长混凝土凝结时间,一定程度上会降低抗压强度,且随着掺量增加,缓凝效果增强、强度降低值增加。但在干燥条件下,掺入SAP的混凝土强度降低较少,说明SAP在干燥条件下对自密实混凝土有一定的自养护效果。

| Abstract: | From the properties of self compacting concrete,the methods of super absorbent polymer inner addition and the influence of it on SCC were preliminary studied.The result showed that under the standard curing,the setting time of concrete with SAP prolonged and the compressive strength decreased.As the content of SAP increased,the setting time would be longer and the strength would be much lower.However,under the dry condition,the strength of concrete with SAP decreased less,which indicated that in dry conditi... |
