High-fluidity ultrahigh-strength cement-based material and preparation method thereof
The invention discloses a high-fluidity ultrahigh-strength cement-based material and a preparation method thereof. The cement-based material comprises the following components in parts by mass: 50-100parts of cement, 20-35 parts of micro-beads, 10-15 parts of slag, 80-100 parts of fine aggregate and 1.5-2.5 parts of a water reducing agent. The preparation method comprises the following steps: 1)weighing the cementing material and the fine aggregate in proportion, and uniformly mixing and stirring to obtain powder; 2) weighing a water reducing agent in proportion, and fully and uniformly stirring the water reducing agent with water to obtain an aqueous solution; 3) slowly adding the aqueous solution into the powder, fully and uniformly stirring, filling the mold with the mixture, and finally performing vibration molding; and 4) curing under standard curing conditions to obtain the high-fluidity ultrahigh-strength cement-based material. The provided ultrahigh-strength cement-based material mainly solves the problem that an ultrahigh-strength cement-based material is poor in fluidity, the 28d strength reaches 100 MPa or above, the fluidity reaches 200 mm or above, and the high-fluidity ultrahigh-strength cement-based material has the advantages of high fluidity and high strength.
本发明公开了一种大流动性超高强水泥基材料及其制备方法，该水泥基材料按照质量份包括以下组分：水泥50～100份、微珠20～35份、矿渣10～15份、细集料80～100份、减水剂1.5～2.5份。其制备方法如下：1)按比例称取胶凝材料、细集料并混合搅拌均匀得粉料；2)按比例称取减水剂，并与水充分搅拌均匀得水剂；3)将水剂缓慢加入粉料中，充分搅拌均匀后填充满模具，最后振动成型；4)在标准养护条件下养护得到所述的大流动性超高强水泥基材料。本发明提供的超高强水泥基材料重点解决了超高强水泥基材料流动性差的问题，28d强度达100MPa以上，流动度达200mm以上，具有流动性高、强度高的特点。
