Dry-mixed thin-layer masonry mortar
The invention provides a preparation method of thin-layer dry-mixed mortar. Machine-made sand is selected from compression-resistant material balls and rock particles, and the compression-resistant material balls are spherical, so that the mortar has good workability and flowability; and the crushed rock particles are irregular, so that the bonding performance of the mortar is improved. A water-retaining agent effectively reduces the loss of water, so that the mortar has excellent workability. Added sepiolite and diatom stone can absorb water, serve as a carrier of the water-retaining agent and are effectively matched with the components of the mortar, so that the bonding strength of the mortar is improved. After the water in the mortar is volatilized, the water-retaining agent is cured into a special net-shaped structure, so that the bonding strength of the upper and lower surfaces of a brick body is improved. A flocculating agent is added to adjust the overall uniformity of the mortar, and meanwhile, modified carbon fibers and modified lotus root fibers are added into the flocculating agent, so that a grid structure can be formed in the mortar solidification process, and the mortar has the freeze-thaw resistance.
本发明提供了一种薄层干混砂浆的制备方法。其中，所用机制砂选用抗压料球和岩石颗粒，抗压料球为球形，使砂浆具有良好的和易性以及流动性，岩石粉碎颗粒为不规则形状，增加了砂浆的粘结性能。保水剂有效减少水分的流失，使砂浆具有优良的和易性。加入的海泡石、硅藻石可吸收水分，同时作为保水剂的载体，有效与砂浆的成分进行配合，增加砂浆的粘结力度。在砂浆中的水分挥发后，保水剂固化为特殊的网状结构，增加砖体上下表面的粘结强度。添加絮凝剂，调节砂浆的的整体均匀性，同时絮凝剂中添加有改性的碳纤维和改性藕丝纤维，在砂浆凝固过程中可形成网格结构使砂浆具有抗冻融能力。
