Low-cost and low-shrinkage coarse aggregate UHPC suitable for cast-in-place and preparation process thereof
The invention discloses a low-cost and low-shrinkage coarse aggregate UHPC suitable for cast-in-place and a preparation process thereof, belongs to the field of building materials, and aims to provide the low-cost and low-shrinkage coarse aggregate UHPC suitable for cast-in-place. The coarse aggregate comprises the following components: water, cement, fine aggregate, basalt coarse aggregate, a high-activity mineral admixture component, a low-activity joint sealing material component, steel fibers, a water reducing component and a defoaming component, and the mass ratio of the water to the cement to the fine aggregate to the basalt coarse aggregate to the high-activity mineral admixture component to the low-activity joint sealing material component to the steel fibers to the water reducing component to the defoaming component is (0.230-0.240):1:1.25:(1.80-1.95):(0.18-0.21):(0.17-0.19):(0.19-0.25):(0.0155-0.0160):(0.00224-0.00230). The coarse aggregate UHPC has the advantages of ultrahigh strength, durability, low shrinkage and the like.
一种适用于现场浇筑低成本低收缩的粗骨料UHPC及其制备工艺，属于建筑材料领域，目的在于提供一种适用于现场浇筑低成本低收缩的粗骨料UHPC，包括如下组分：水、水泥、细骨料、玄武岩粗骨料、高活性矿物掺合料组分、低活性填缝料组分、钢纤维、减水组分和消泡组分，其中，水、水泥、细骨料、玄武岩粗骨料、高活性矿物掺合料组分、低活性填缝料组分、钢纤维、减水组分与消泡组分的质量比为0.230～0.240：1：1.25：1.80～1.95：0.18～0.21：0.17～0.19：0.19～0.25：0.0155～0.0160、0.00224～0.00230。本发明的粗骨料UHPC兼顾超高强、耐久及低收缩等优点。
