Abstract

Soil ruins hold historical significance and serve as witnesses to past civilizations. High temperatures cause soil moisture to evaporate and soil to shrink, leading to cracking issues and making preservation a global challenge. P(AA-AM-AMPS) (Acrylic acid -Acrylamide-2-Acrylamide-2-methy-propenesulfonic acid) composites solve this problem by combining absorbent materials with loess. In this study, P(AA-AM-AMPS) was prepared using a solution method. The water absorption, water retention, air permeability, and compressive strength of P(AA-AM-AMPS) in loess were studied. The results show that after adding P(AA-AM-AMPS) to loess, there is no obvious color difference compared with the blank sample, and the air permeability of the reinforced loess is basically the same as that of the blank soil. After aging resistance tests, the surface cracking of soil clods is significantly reduced compared to that of the blank samples, and their compressive strength improved from 1.8 N/mm to 2.6 N/mm.

摘要

土壤遗迹具有历史意义，是过去文明的见证者。高温会导致土壤水分蒸发和土壤收缩，从而引发开裂问题，使得保护成为一项全球性挑战。P(AA - AM - AMPS)（丙烯酸 - 丙烯酰胺 - 2 - 丙烯酰胺 - 2 - 甲基丙磺酸）复合材料通过将吸水材料与黄土相结合解决了这一问题。在本研究中，采用溶液法制备了P(AA - AM - AMPS)。研究了P(AA - AM - AMPS)在黄土中的吸水性、保水性、透气性和抗压强度。结果表明，在黄土中添加P(AA - AM - AMPS)后，与空白样品相比颜色无明显差异，加固后黄土的透气性与空白土壤基本相同。经过抗老化试验后，土块表面开裂情况比空白样品显著减少，其抗压强度从1.8 N/mm提高到2.6 N/mm。
