The invention discloses a repairing material for ancient building black brick wall cracks and a construction process, and belongs to the field of ancient building repairing. Quicklime, slaked lime, black brick ash, quartz sand, 107 building glue powder, hydroxypropyl methyl cellulose, starch ether, a water reducing agent and an antifoaming agent are fully mixed according to a mass ratio, and thenprepared silicone acrylic emulsion modified glutinous rice slurry is added and fully stirred to obtain the product. The repairing material meets the requirements of cultural relic protection and repair, has good flowability, is beneficial to grouting operation and full filling of gaps, and has good compressive strength and bonding strength, good toughness, small shrinkage rate, good water resistance and strong ageing resistance after being cured. The repairing material has good adhesive force with black bricks, the appearance color is close to that of a black brick wall, the repairing materialhas good compatibility with the black brick wall, the cost is low, and the economic practicability is high. The repair material construction process is elaborated in detail, construction is convenient and fast, and the rework period can be effectively shortened.
Description
technical field [0001] The invention belongs to the field of ancient building restoration, and relates to a repairing material and construction technology for cracks in ancient building brick bodies. Background technique [0002] As a cultural heritage, ancient architecture not only has a strong historical and cultural heritage, but also has important value in art, technology, architecture, aesthetics and other aspects. Green bricks are one of the commonly used ancient building materials. Cracks often occur in the walls of blue bricks due to the following reasons: (1) Temperature cracks: between the walls of blue bricks are often due to thermal expansion and contraction of materials, swelling and shrinking when wet. Inconsistent shrinkage caused by different conditions leads to cracking of the wall; (2) settlement cracks: cracks in the wall caused by uneven settlement of the foundation foundation; (3) deformation cracks: cracks in the wall surface caused by deformation such ...
