The invention relates to the technical field of concrete, and provides quick-setting early-strength concrete and a preparation method thereof. The quick-setting early-strength concrete is prepared from, by weight, 150-200 parts of cement, 20-30 parts of slag, 5-10 parts of silica fume, 320-360 parts of coarse aggregate, 250-280 parts of fine aggregate, 3-4 parts of early strength agent, 0.5-0.6 part of water reducing agent and 50-70 parts of water, the early strength agent is prepared from aluminum sulfate, titanium silicon carbide and ammonium acetate, and the mass ratio of the aluminum sulfate to the titanium silicon carbide to the ammonium acetate is 3.5: (2-3): (1.3-2). By means of the technical scheme, the problems that in the prior art, the long-term strength of the quick-setting early-strength concrete is reduced, and durability is poor are solved.
本发明涉及混凝土技术领域，提出了一种快凝早强混凝土及其制备方法。所述快凝早强混凝土，包括以下重量份的组分：水泥150‑200份，矿渣20‑30份，硅灰5‑10份，粗集料320‑360份，细集料250‑280份，早强剂3‑4份，减水剂0.5‑0.6份，水50‑70份，所述早强剂由硫酸铝、钛碳化硅、醋酸铵组成，所述硫酸铝与钛碳化硅、醋酸铵的质量比为3.5：(2‑3)：(1.3‑2)。通过上述技术方案，解决了相关技术中的快凝早强混凝土后期强度倒缩、耐久性差的问题。
