Multi-component gel system STC ultrahigh-toughness concrete material for bridge deck pavement
The invention belongs to the technical field of concrete materials, and provides a multi-component gelling system STC ultrahigh-toughness concrete material for bridge deck pavement, in each cubic meter of the STC material, the total amount of the gelling material is 950-1050kg, that is, the ratio of the gelling material to the bone is 1:1.0 to 1:1.1 and the water-binder ratio is 0.16 to 0.18; the mixing amount of the water reducing agent accounts for 2.5%-3.0% of the total mass; the doping amount of the steel fibers accounts for 2.5%-3.5% of the total volume; the cementing material is prepared by mixing the following components in percentage by weight: ordinary Portland cement, microbeads, silica fume and microcrystalline calcium aluminoferrite in proportion; the aggregate is formed by mixing quartz sand of 10-20 meshes and quartz sand of 70-140 meshes in proportion. The concrete has excellent mechanical properties and good fluidity, meets the design and construction requirements, and is especially suitable for bridge deck pavement engineering and road engineering which need to improve the cracking strength of the member and improve the durability of the structure so as to increase the overall rigidity of the structure and prolong the fatigue life of the structure.
本发明属于混凝土材料技术领域，提供一种桥面铺装用多元胶凝体系STC超高韧性混凝土材料，每立方米STC材料中：胶凝材料总量为950～1050kg，即胶骨比为1:1.0～1:1.1；水胶比为0.16～0.18；减水剂的掺量占总质量的2.5%～3.0%；钢纤维掺量占总体积的2.5%～3.5%；胶凝材料按照重量百分比计为：普通硅酸盐水泥、微珠、硅灰、微晶铁铝酸钙按比例混合而成；骨料为：10‑20目石英砂与70‑140目石英砂按比例混合而成。力学性能优异，流动性良好，满足设计及施工要求，特别适合用于需要提高构件开裂强度，提升结构的耐久性能的桥面铺装工程及道路工程中，以增加结构的整体刚度以及疲劳寿命等。
