Cement mortar for improving crack resistance of concrete drainage pipeline and preparation method thereof
The invention relates to cement mortar for improving crack resistance of a concrete drainage pipeline and a preparation method of the cement mortar, belongs to the technical field of building materials, and has the characteristics of pressure resistance, crack resistance and uniform distribution. The polyether type spandex fiber, the medium sand in the river sand and the silicate P.I cement are selected as main raw materials, the strength of the silicate cement is high, and the polyether type spandex fiber has the advantages of high strength and stable chemical property; the medium sand has the characteristics of moderate particles, smooth surface and low impurity content, the smooth surface can reduce abrasion and damage to building materials, and the strength and durability of the cement mortar concrete can be greatly improved through combination of various materials with excellent performance. Due to the principle that charges of the same kind repel each other, components in the pretreated spandex fibers and the cement mortar are uniformly dispersed in the pretreated spandex fibers through chemical action under the action of a dispersing agent, so that the strength, the permeability resistance and the crack resistance of the cement mortar are integrally improved.
本发明涉及一种提高混凝土排水管道抗裂性的水泥砂浆及其制备方法，属于建筑材料技术领域，具有抗压、抗裂以及分布均匀的特点。本发明选用了聚醚型氨纶纤维、河砂中的中砂、硅酸盐类P·I水泥作为主要原料，硅酸盐水泥的强度较高，聚醚型氨纶纤维具有高强度和化学性质稳定的优点；中砂具有颗粒适中、表面光滑和杂质含量少的特点，光滑的表面可以减少对建筑材料的磨损和破坏，多种优异性能材料的结合，可以大大提高了水泥砂浆混凝土的强度和耐久性。而且经过预处理后的氨纶纤维，由于同种电荷相互排斥原理，在分散剂的作用下，氨纶纤维与水泥砂浆中的成分通过化学作用均匀的分散在其中，从整体上提高了水泥砂浆的强度、抗渗透性和抗裂性。
