土遗址用防水剂的应用性能对比研究
Comparative Study on the Application Performance of Waterproofing Agents for Earthen Sites
摘要
Abstract
There are numerous existing earthen sites in China,but research on targeted protective materials is not yet in-depth.For this reason,three different types of waterproof agents(silane,alkyl silicate and Fluoroalkane)were selected to systematically compare the influence of different types of waterproof agents on the waterproof performance of soil samples and their mechanism through macro tests such as capillary water absorption,color difference analysis,air permeability and micro analysis such as contact angle,infrared spectrum and scanning electron microscope.The results showed that silane based waterproofing agents have the best durability,and the coating formed on the soil surface has the strongest hydrophobicity,with a water contact angle of 115°,a color difference value of 0.75,and an air permeability of 3.5%.The comprehensive properties are closest to those of untreated test blocks.This excellent performance is attributed to the highly ordered directional arrangement of its alkyl chains,forming a dense low surface energy hydrophobic film.关键词
