The invention relates to the technical field of concrete, in particular to low-shrinkage low-viscosity ultrahigh-strength concrete which comprises Portland cement, fly ash microspheres, silica fume, a water reducing agent, modified saponification waste residues, sand, gravel and water. The low-shrinkage low-viscosity ultrahigh-strength concrete is prepared from the following components in mass by per cubic meter (kg/m<3>): 460 to 520kg/m<3> of Portland cement, 40 to 55 kg/m<3> of fly ash microbeads, 40 to 60 kg/m<3> of silica fume, 20 to 30 kg/m<3> of water reducing agent, 60 to 120 kg/m<3> of modified saponification waste residues, 300 to 400 kg/m<3> of sand, 720 to 880 kg/m<3> of gravel and 140 to 180 kg/m<3> of water. The provided low-shrinkage low-viscosity ultrahigh-strength concrete uses relatively low content of viscous component, and is low in shrinkage, high in strength and relatively low in viscosity. The concrete pumping construction efficiency is guaranteed, and pumping accidents are reduced.
本发明涉及混凝土技术领域，尤其涉及一种低收缩低粘度超高强混凝土，所述低收缩低粘度超高强混凝土包括有硅酸盐水泥、粉煤灰微珠、硅灰、减水剂、改性皂化废渣、砂、碎石和水，各成分的单方用量配比(kg/m3)如下：硅酸盐水泥460‑520、粉煤灰微珠40‑55、硅灰40‑60、减水剂20‑30、改性皂化废渣60‑120、砂300‑400、碎石720‑880和水140‑180，本发明提出的低收缩低粘度超高强混凝土，其使用了较低的胶粘组分，其收缩率低、强度高，且粘度也相对较低，保证泵送混凝土施工效率，减小泵送事故发生。
