The invention discloses a construction method for a high-
ductility heat-insulating masonry wall. The method comprises the following steps: according to a design size of the cross section of the masonry wall, smearing a layer of high-performance masonry
mortar on a position where the masonry wall is needed; paving building blocks on the high-performance masonry
mortar, and smearing the high-performance masonry
mortar, according to a design height of the masonry wall, completing the masonry of the wall, and curing for 7 days so that the wall reaches the
initial strength; smearing a high-performance
cement-based material on the surface of the completed masonry wall, and laying a
fiber weaving net on the high-performance
cement-based material, and smearing the high-performance
cement-based material on the
fiber weaving net,
wetting and curing for 28 days until reaching an age of the high-performance cement-based material; and smearing
polymer adhesive mortar on the high-performance cement-based material at one side, contacting with an outside
natural environment, of the masonry wall, and laying a heat-insulating board on the
polymer adhesive mortar, finally smearing decoration mortar on the heat-insulating board. The method is capable of effectively improving the
ductility of the newly constructed masonry wall, reducing a risk that the masonry structure is seriously damaged,even collapsed, in an earthquake, effectively improving the heat-insulating performance of the newly constructed masonry wall, and reducing the construction
energy consumption of the masonry wall.
