The invention discloses a super-early-strength low-shrinkage self-compacting fiber cement-based reinforcing material and a preparation method thereof, and the super-early-strength low-shrinkage self-compacting fiber cement-based reinforcing material comprises 60-80 parts of cement, 30-60 parts of sand, 5-10 parts of mineral powder, 5-10 parts of modified mineral powder, 5-10 parts of modified clay, 0.01-0.05 part of cellulose ether, 0.01-0.03 part of an air entraining agent, 5-10 parts of light-burned dolomite, 20-40 parts of water, polypropylene fibers and steel fibers. The polypropylene fiber accounts for 0.1-0.4% of the total volume of the material, and the steel fiber accounts for 0.2-0.8% of the total volume of the material, the cellulose ether, the air entraining agent and other additives are adopted to improve the fluidity and cohesiveness of the cement-based material, the water consumption required by the material is reduced, and the filling property and segregation resistance of the material are improved; while the early strength is ensured, the early strength is synergistically enhanced, the shrinkage is reduced, the segregation resistance of the slurry is improved, the workability is good, and a complex structure can be uniformly and compactly filled by virtue of the self weight of the material.
本发明公开了一种超早强低收缩自密实纤维水泥基增强材料及制备方法，包括水泥60‑80份、砂30‑60份、矿粉5‑10份、改性矿粉5‑10份、改性粘土5‑10份、纤维素醚0.01‑0.05份、引气剂0.01‑0.03、轻烧白云石5‑10份、水20‑40份以及聚丙烯纤维和钢纤维，聚丙烯纤维占材料总体积的0.1‑0.4％，钢纤维分占材料总体积的0.2‑0.8％，本发明采用纤维素醚和引气剂等外加剂对水泥基材料的流动性和粘聚性进行改善，降低材料所需用水量，提升材料的填充性和抗离析性，采用改性矿粉和改性粘土，在保证早期强度的同时，协同增强早期强度和降低收缩并提升浆料的抗离析性，工作性好，能够依靠材料自重均匀密实填充复杂结构中。
