Adhesive mortar and preparation method thereof
The invention discloses adhesive mortar and a preparation method thereof. The adhesive mortar comprises the following raw materials in parts by weight: 50-70 parts of sulphoaluminate cement, 10-30 parts of fly ash, 5-15 parts of copper tailings, 3-10 parts of polypropylene fibers and 8-15 parts of an auxiliary agent, wherein the auxiliary agent comprises 10%-30% of an expanding agent, 20%-30% of nano filler and 50%-60% of polymer powder; the invention relates to the technical field of building materials. According to the adhesive mortar and the preparation method thereof, the polypropylene fibers are doped into the mortar, so that the breaking strength of the mortar can be obviously improved, and meanwhile, the compressive strength of the mortar can also be improved; according to the present invention, the nano-filler is doped, the nano-fibers and the nano-sheets have the fiber reinforcement effect, and the nano-fibers and the nano-sheets have the high tensile strength so as to improve the mechanical property of the mortar, and the nano-filler can effectively fill the gaps between the cement particles, improve the compactness of the cement matrix, optimize the pore size distribution, and improve the strength of the cement matrix; therefore, the mechanical property of the mortar is enhanced.
本发明公开了一种粘结砂浆及其制备方法，该粘结砂浆包括以下重量份原料：硫铝酸盐水泥50～70份、粉煤灰10～30份、铜尾矿5～15份、聚丙烯纤维3～10份、辅助剂8～15份；其中，所述辅助剂包括膨胀剂10％～30％、纳米填料20％～30％、聚合物粉末50％～60％；本发明涉及建筑材料技术领域。该粘结砂浆及其制备方法，通过在砂浆中掺加聚丙烯纤维，可以明显地提高砂浆的抗折强度，同时也能提高其抗压强度；通过纳米填料的掺加，纳米纤维和纳米片具有纤维增强效应，纳米纤维和纳米片具有较高的抗拉强度，从而改善砂浆的力学性能，同时纳米填料可以有效地填充水泥颗粒之间的间隙，提高水泥基体的密实度，优化孔径分布，从而增强砂浆的力学性能。
