Super-early-strength UHPC premix for bridge expansion joints and manufacturing method thereof
The invention relates to the technical field of traffic engineering materials, and discloses a super-early-strength UHPC premix for bridge expansion joints. Comprising the following raw materials in parts by weight: Portland cement, quartz sand fine ground mineral powder, silica fume, an inorganic early strength agent, a viscosity-reducing thixotropic agent, a nano anti-permeability agent, an internal curing agent and copper-plated steel fibers. The early hydration speed of ordinary Portland cement is accelerated by compounding the inorganic early strength agent, the viscosity reduction thixotropic agent is added to reduce the viscosity of the material, the nano anti-permeability agent is added to improve the pore structure and pore distribution of a hydration product, and the internal curing agent is added to adjust the hydration heat release temperature curve of the cement. Ordinary Portland cement is used as a main cementing material, quartz sand is used as an aggregate, mineral micro powder is used as an active mixed material, and a polycarboxylate superplasticizer and the like are added to prepare the super-early-strength UHPC premix.
本发明涉及交通工程材料技术领域，且公开了一种用于桥梁伸缩缝超早强UHPC预混料，包括以下重量份数配比的原料：硅酸盐水泥石英砂磨细矿粉硅灰无机早强剂降粘触变剂纳米抗渗剂内养护剂镀铜钢纤维该用于桥梁伸缩缝超早强UHPC预混料及其制造方法，通过复配无机早强剂促进普通硅酸盐水泥早期水化速度、添加降粘触变剂降低材料本身的粘滞性、添加纳米抗渗剂改善水化产物的孔结构和孔分布、添加内养护剂调整水泥水化放热温度曲线，以普通硅酸盐水泥为主要胶凝材料、以石英砂为骨料，以矿物微粉为活性混合材料，添加聚羧酸减水剂等，制成超早强UHPC预混料。
