The Application of Various Remediation Soils in City Wall Restoration
摘要
Abstract
Based on the destruction of the Great Wall in Ming Dynasty,this paper makes a comparative study on the role of various types of remediation soil in the restoration of the city wall,analyzes the water absorption,pressure resistance,impermeability and crack resistance of the remediation soil,and compares the restoration characteristics of traditional modified soil,chemically modified soil and bacteria-induced soil,trying to find the most comprehensive and effective soil type for the restoration of the city wall.The results show that the traditional modified soil-pseudo-ginseng lime soil and glutinous rice plaster modified soil have excellent comprehensive practical properties.The chemical modified soil has the best performance when it contains 2.0%sodium methylsilicate,5.0%lime and 2.0%rubber powder.The bacteria-induced soil with concentrations of 2.8×108 CFU/mLBacillus subtilis and 1×105 CFU/mL Bacillus megaterium and Bacillus pasteurella has excellent comprehensive practical properties.关键词
