Non-cement-based ultra-high performance concrete and preparation method thereof
The invention relates to non-cement-based ultra-high performance concrete and a preparation method thereof, and belongs to the technical field of building materials. The non-cement-based ultra-high performance concrete comprises the following raw material components: mineral powder, silica fume, fly ash, silica powder, fine sand, medium sand, coarse sand, a sodium silicate solution, sodium hydroxide, a superplasticizer and steel fibers. The raw materials used by the non-cement-based ultra-high performance concrete are all conventional raw materials and are wide in source; the mineral powder isprocessed from solid waste and is used as a mineral admixture in the non-cement-based ultra-high performance concrete, so that the concrete is green and environment-friendly; the initial setting timeof the non-cement-based ultra-high performance concrete mixture can be adjusted according to the modulus of sodium silicate, so that the initial setting time of the non-cement-based ultra-high performance concrete mixture required by different construction requirements can be met; the non-cement-based ultra-high performance concrete is high in early strength, the 7-day compressive strength of thenon-cement-based ultra-high performance concrete is larger than or equal to 120 MPa, and the 28-day compressive strength of the non-cement-based ultra-high performance concrete is larger than or equal to 160 MPa.
本发明涉及一种非水泥基超高性能混凝土及其制备方法，属于建筑材料技术领域。本发明提供的一种非水泥基超高性能混凝土，包括如下原料组分：矿粉、硅灰、粉煤灰、硅微粉、细砂、中砂、粗砂、硅酸钠溶液、氢氧化钠、高效减水剂和钢纤维。本发明的非水泥基超高性能混凝土使用的原材料，均是常规原材料，来源广泛；矿粉是通过固体废弃物加工而成，以矿粉作为非水泥基超高性能混凝土中的矿物掺合料，绿色环保；非水泥基超高性能混凝土拌合物的初凝时间可以根据硅酸钠的模数来调节，因此，它可以满足不同施工要求所需非水泥基超高性能混凝土拌合物的初凝时间；本发明所述的非水泥基超高性能混凝土的早期强度高，其7天抗压强度≥120MPa，28天抗压强度≥160MPa。
