利用普通硅酸盐水泥、粉煤灰、微硅粉等胶凝剂,发泡剂以及聚丙烯纤维制备出矿用无机发泡重填材料,并对纤维提高无机发泡充填材料各项性能做了实验研究。研究并分析了聚丙烯纤维的长度、掺量以及不同的掺加方式对无机发泡充填材料的力学性能的影响,得出聚丙烯纤维对无机发泡充填材料的抗压强度、抗折强度有一定的提高作用,并且能够有效抑制材料的干燥收缩的结论。因此,聚丙烯纤维的掺入对无机发泡充填材料力学性能的改善有较好的促进作用。
The use of ordinary Portland cement, fly ash, silica fume and other gelling agents, foaming agent and polypropylene fiber prepared inorganic mineral foam re-filling material, and fiber to improve the performance of inorganic foam filling material to do Experimental study The influence of polypropylene fiber length, dosage and different blending methods on the mechanical properties of inorganic foamed filling materials was studied and analyzed. The compressive strength and flexural strength of polypropylene foams for inorganic foam filling materials were obtained A certain increase in the role, and can effectively inhibit the drying shrinkage conclusion. Therefore, the incorporation of polypropylene fibers improve the mechanical properties of inorganic foam filling material has a better role in promoting.
