Ultrahigh-toughness steel bridge deck pavement premix
The invention relates to the technical field of bridge deck pavement, and discloses an ultrahigh-toughness steel bridge deck pavement premix which comprises the following raw materials in parts by weight: a component A: 200-400 parts by mass of Portland cement, 200-500 parts by mass of quartz sand, 100-300 parts by mass of ground mineral powder, 50-150 parts by mass of floating beads, 1-3 parts by mass of a water reducing agent and 1-7 parts by mass of a water retaining agent; and the component B comprises the following components in parts by mass: 80-200 parts of copper-plated steel fibers. According to the ultrahigh-toughness steel bridge deck pavement premix, the closest accumulation is realized by compounding ordinary Portland cement, grading high-strength fine aggregate, ground granulated blast furnace mineral powder, silica fume and the like; the floating beads are added to reduce the viscosity of the material and improve the pore structure and pore distribution of a hydration product, the water-retaining agent is added to adjust the water consumption required in each stage of cement hydration so as to correct an exothermic temperature curve, and the copper-plated steel fibers are added to greatly improve the toughness of the material, so that the ultrahigh-toughness steel bridge deck pavement premix is prepared. And the advantages of high toughness and high strength are achieved.
本发明涉及桥面铺装技术领域，且公开了一种超高韧性钢桥面铺装预混料，包括以下重量份数配比的原料：A组份质量份数：硅酸盐水泥200‑400份，石英砂200‑500份，磨细矿粉100‑300份，漂珠50‑150份，减水剂1‑3份，保水剂1‑7份；B组份质量份数：镀铜钢纤维80‑200份。该超高韧性钢桥面铺装预混料，通过复配普通硅酸盐水泥、级配高强度细集料、磨细粒化高炉矿粉、硅灰等实现最紧堆积，添加漂珠降低材料本身的粘滞性、改善水化产物的孔结构和孔分布、添加保水剂调整水泥水化各阶段所需用水量进而修正放热温度曲线，添加镀铜钢纤维以大幅度提升材料韧性，制成超高韧性钢桥面铺装预混料，达到了韧性高和强度高的优点。
