Thin-layer epoxy polymer concrete suitable for steel box girder bridge deck and preparation method of thin-layer epoxy polymer concrete
The invention discloses thin-layer epoxy polymer concrete suitable for a steel box girder bridge deck. The thin-layer epoxy polymer concrete is composed of an epoxy component, a fiber material and a graded mineral aggregate. The invention further discloses a production and preparation method of the thin-layer epoxy polymer concrete suitable for the steel box girder bridge deck. The production andpreparation method specifically comprises the following steps that S01, the dry graded mineral aggregate and the added fiber material are mixed for 15s-60s; S02, the epoxy component is added, stirringis carried out for 30s-60s for paving; and S03, a double-steel-wheel road roller is used for rolling after paving. According to the thin-layer epoxy polymer concrete suitable for the steel box girderbridge deck, the latent epoxy component is adopted, and final curing of the thin-layer epoxy polymer concrete is promoted through the temperature of the anti-skid abrasion pavement upper layer. Through a secondary curing mode, not only is the construction difficulty of the epoxy polymer concrete reduced, but also the cohesiveness of the epoxy polymer concrete and a pavement upper layer is enhanced.
本发明专利公开了一种适用于钢箱梁桥面的薄层环氧聚合物混凝土，所述薄层环氧聚合物混凝土由环氧组分、纤维材料和级配矿料组成。还公开了一种适用于钢箱梁桥面的薄层环氧聚合物混凝土的生产制备方法，具体如下：S01、将干燥级配矿料，添加纤维材料拌和15s～60s；S02、加入环氧组分，拌和30s～60s后即可摊铺；S03、摊铺后应使用双钢轮压路机进行碾压。本发明适用于钢箱梁桥面的薄层环氧聚合物混凝土，采用潜伏型环氧组分，通过抗滑磨耗铺装上层的温度，促使本薄层环氧聚合物混凝土完成最终的固化。通过二次固化方式，不但有利于降低本环氧聚合物混凝土的施工难度，同时还有利于增强本环氧聚合物混凝土同铺装上层的粘结性。
