The Experimental Study on Consolidation of Acrylic Non-aqueous Dispersion for Kiln Qionglai Monuments in Chengdu, China

摘要

It is difficult to preserve earth monument in wet area. To solve this problem, a Chinese scholar, professor Zhou Shuanglin, developed a consolidation agent named acrylic non-aqueous dispersion. But the study on this consolidation agent is still in its initial stage, most of its experimental researches are limited to northwest china and no research reports aimed at southwest China wet area 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, the changes of color, compressive strength and hydrolysis 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.
