The Experimental Study on Consolidating Effect of Acrylic Non-Aqueous Dispersion for Earthen Ruins in Southwest China’s Moist Areas

Abstract

It is a worldwide difficulty to preserve earth monument in wet area. To solve this problem, professor Zhou Shuanglin, an expert of earth monument preserving with College of Archaeology and Museum, Peking University, developed a consolidation agent named acrylic non-aqueous dispersion. But the study on this consolidation agent is still in its initial stage at present for most of its experimental researches are limited to northwest china and no research reports aimed at wet area in southwest China were found so far. To check out the efficiency of this consolidation agent in wet area, southwest China, a consolidating experiment was conducted by applying this consolidation agent to soil samples from kiln Qionglai earthen monuments located in outskirt of Chengdu city, the capital of Sichuan province. In this experiment, seeping speed, the changes of compressive strength and short-term water resistance of specimens after consolidating were investigated and compared with those for northwest area. The study shows that acrylic non-aqueous dispersion consolidation agent developed by professor Zhou Shuanglin is also effective to a certain degree for the earth monument in wet area, southwest China.
