Steel-concrete composite structure bridge deck slab cast-in-place concrete and construction process thereof
The invention relates to the field of highway bridge construction, and particularly discloses steel-concrete composite structure bridge deck slab cast-in-place concrete and a construction technology thereof. The steel-concrete composite structure bridge deck slab cast-in-place concrete comprises the following raw materials in parts by weight: 1000-1200 parts of gravel, 480-500 parts of sand, 300-360 parts of cement, 100-120 parts of fly ash, 150-170 parts of water and 50-100 parts of a composite toughening component, wherein the composite toughening component comprises an adhesive, modified toughening fibers and modified coconut fibers in a weight ratio of (3-6): (1-3): 1; the construction process comprises the following steps: firstly, mixing the gravel, the sand, the cement and the fly ash, then adding the water, finally adding the composite toughening component, and uniformly stirring, so that the prepared cast-in-place concrete is used for pouring the bridge deck slab. The steel-concrete composite structure bridge deck slab cast-in-place concrete can be used for bridge deck slab construction and has the advantage of reducing shrinkage deformation and cracking.
本申请涉及公路桥梁施工领域，具体公开了一种钢混组合结构桥面板现浇混凝土及其施工工艺。钢混组合结构桥面板现浇混凝土包括以下重量份的原料：碎石1000～1200份，砂480～500份，水泥300～360份，粉煤灰100～120份，水150～170份，复合增韧组分50～100份，所述复合增韧组分包括粘接剂、改性增韧纤维和改性椰壳纤维三者重量之比为(3～6):(1～3):1；其施工工艺为：先将碎石、砂、水泥和粉煤灰混合，然后加入水，最后加入复合增韧组分搅拌均匀，制得的现浇混凝土用于桥面板浇筑。本申请的钢混组合结构桥面板现浇混凝土可用于桥面板施工，其具有减少收缩变形开裂的优点。
