Example Embodiment

[0040] Example 1

[0041] The present embodiment has the manufacturing method of the masonry wall with high seismic resistance and high shear resistance, and the specific steps are:

[0042] 1) Immerse the brick test block with water;

[0043] 2) Simultaneously prepare masonry mortar, and masonry mortar adopts PVA-ECC:

[0044] ① According to the mass ratio of water: cement: fly ash: quartz sand: water reducing agent: fiber = 1:1.83:2.197:1.463:0.024; 0.063 to weigh the raw materials;

[0045] ②Put the weighed cement, fly ash and quartz sand into the mixing pot and dry for 3 to 5 minutes, until the mixing is uniform, and the speed of the mixing pot is about 40 rpm;

[0046] ③ Then add the weighed water and water reducing agent, stir for 6 minutes until the water reducing agent is fully effective;

[0047] ④ Finally, put in the PVA fibers, adjust the speed of the stirring pot to about 60 rpm, and wet-mix for 5 to 7 minutes until the PVA fibers are evenly dispersed;

[0048]...

Example Embodiment

[0060] Example 2

[0061] Example 2 adopts the same test method, test procedure and test specimen as in Example 1, except that the masonry mortar is traditional cement mortar, and the composition mass ratio is water:cement:sea sand=1-3:1:1.375, The plastering mortar is also traditional cement mortar, and the composition mass ratio is water:cement:sea sand=1-3:1:3.

Example Embodiment

[0062] Example 3

[0063] Example 3 adopts the same test method, test procedure and test specimen as in Example 1, except that the plastering mortar is traditional cement mortar, and the composition mass ratio is water:cement:sea sand=1-3:1:3.

Abstract

The invention provides a manufacturing method of a brick wall with high shear resistance and shock resistance. The manufacturing method comprises the following steps that bricks are taken out, polyvinyl alcohol fiber reinforced cement-based composite materials serve as masonry mortar, and a three-one bircklaying method is adopted for bricklaying; after bricklaying is completed, plastering is conducted on the both sides of a wall body, and plastering mortar is high ductility materials, wherein the high ductility materials are prepared from water, binding materials, silica sand and fibers, the mass ratio of the water to the binding materials, the silica sand and the fibers is 1:2.44:(0.8-1):0.038, the binding materials are cement and fly ash, and the fly ash accounts for 40%-50% of the total amount of the binding materials; and after plastering is conducted, water is sprayed onto the wall body for curing in one to seven days, and then the brick wall is obtained after the wall body is cured for 28 days under the outdoor environment condition. According to the manufacturing method of the brick wall with high shear resistance and shock resistance, the shear resistance of the brick wall can be remarkably improved, and the shock resistance can also be greatly improved.

Description

technical field [0001] The invention relates to the technical field of masonry walls, in particular to a method for manufacturing a masonry wall with high shear resistance and high seismic performance. Background technique [0002] In all kinds of buildings in my country, masonry structures account for a large proportion. At present, there are still many places where masonry structures need to be used, such as infill walls of concrete frame structures, and many masonry walls are in disrepair. The traditional masonry walls use traditional masonry mortar (water: cement: sea sand = 1-3: 1: 1.375) to wrap the bricks, build them layer by layer, and then install the wall as a whole. The outer surface is covered with traditional plastering mortar (water:cement:sea sand=1-3:1:3), but whether it is masonry mortar or plastering mortar, its shortcomings are very obvious, due to poor shear resistance, resulting in cracking , the formation of cracks, and some even up to several millimeters...
