| 摘 要： | 沈阳市南五马路公铁立交桥工程框构桥混凝土等级高(C40)、体积大(共7000m3),钢筋绑扎密度高,且工点位于市内。该桥混凝土采用商品混凝土泵送技术,因此混凝土的坍落度比较大,这使混凝土由于干缩及冷缩的作用极易产生收缩开裂,最终可导致钢筋锈蚀,影响结构受力。在施工中使用WG-H

| Abstract: | Railway bridge and culvert works set high demands on leakage, seepage and crack control. In construction the WG-HEA higher effective and anti-crack type water proofing agent is mixed with concrete and strict control is exercised over the casting and curing of the same to have it measure up to the optimum anti-leakage, anti-seepage and anti-crack results. |

| Keywords: | WG-HEA higher effective and anti-crack type water proofing agent rigid water proofing of concrete expansion strengthening belt |
