There are modern historical cement buildings in many cities all around the country. Many of these buildings have both the western architectural aesthetic features and Chinese traditional art forms. Many have irreplaceable historical significance and artistic value. Due to longterm natural factors and human activities, the inner structures of some of these buildings are loose and weak. Protection of these historical cement buildings is a very urgent task. Because of the longterm effects of moisture, sulfur dioxide in the air, etc., the calciumcontaining components of the cement can dissolve resulting in porous structures formed which can further deteriorate. In this study a hydrophilic organosilicon material with good tensile properties was used to consolidate and protect historical cement buildings. The compressive strength of cements consolidated by this material can be doubled. At the same time, this material has good permeability, and the surface appearance of the cement samples is almost unchanged. SEM pictures show that the porosity of consolidated sample decreased significantly compared with the untreated ones since the consolidation material can effectively fill the large pores. In addition, this material is relatively more hydrophilic than other polymeric organosilicon materials, hence the preservation damage is less likely to occur than in the case of buildings treated with strong waterrepellent protective agents. Furthermore, this material is “green” and environmentfriendly because it does not require large amounts of organic solvents. This study has important implications for further exploration and development of cement historic building consolidation materials.
