Humidifying and reinforcing mortar for immature soil wall surface and preparation method of humidifying and reinforcing mortar
The invention discloses humidifying and reinforcing mortar for a raw soil wall surface and a preparation method of the humidifying and reinforcing mortar, and belongs to the technical field of building materials. According to the humidifying and reinforcing mortar for the immature soil wall surface provided by the invention, the air entraining agent is added to introduce pores, and the pores form communicating holes, so that the heat and humidity physical properties of the mortar on an immature soil wall body reinforcing surface layer can be effectively improved, the mortar is coordinated and matched with an immature soil material, and water vapor accumulation and degradation reinforcement are avoided. Meanwhile, the toughness strength of the mortar is enhanced by using the nanocellulose, the compressive strength is enhanced by using the water reducing agent, and the toughness is enhanced by PVA fibers. Within the limited range, the humidifying performance and the reinforcing performance are well considered at the same time. In addition, the nano cellulose fibers and the PVA fibers are hydrophilic materials, have moisture absorption and moisture liberation capabilities, and can further assist the air entraining agent in improving the humidity adjusting performance of the mortar.
本发明公开了一种用于生土墙面的调湿加固砂浆及其制备方法，属于建筑材料技术领域。本发明提供的用于生土墙面的调湿加固砂浆，通过加入引气剂引入孔隙，这些空隙形成连通孔，可以有效改善砂浆在生土墙体加固面层的热湿物理性能，使其与生土材料协调匹配，避免水汽聚集，劣化加固。同时使用纳米纤维素增强砂浆的韧性强度，减水剂增加抗压强度，PVA纤维增强韧性。在本发明限定的范围下，同时很好兼顾的调湿性能和加固性能。此外，纳米纤维素纤维和PVA纤维都是亲水性材料，自身具有吸湿放湿的能力，可以进一步辅助引气剂提高砂浆的调湿性能。
