同一平面水平灰缝应当控制在11-15mm之间，且灰缝横平竖直使砂浆填充

The horizontal mortar joint in the same plane should be controlled between 11-15mm, and the mortar joint should be horizontal and vertical so that the filling rate of mortar is high, and its fullness should not be less than 80%. When ash-laying masonry is used, the vertical mortar joints should be built with a combination of ash mixing and ash adding. During construction, it is strictly forbidden to grouting with water, and it is not allowed to use other construction materials such as stones, wooden wedges, etc. In the jointing of leather bricks, the original slurry should be made flush with the wall surface. And the horizontal mortar joints shall not be less than 90%, the vertical mortar joints shall not be less than 85%, and there shall be no blind joints, cracks, transparent joints, etc. in the horizontal and vertical joints in masonry.

The same plane horizontal gray seam should be controlled between 11-15mm, and the gray seam horizontal vertical so that the mortar filling rate is high, its fullness should not be less than 80%. In the use of gray masonry, vertical ash seams should be used a combination of ash and ash masonry method. In the construction should be strictly prohibited with water slurry sewing, not to use stone, wood wedges and other construction materials pad ash seam masonry, masonry should be with the masonry with the clean gray seam surface, so that the masonry height should not be greater than 4 leather brick, in the seam to make the original pulp pressure seam and wall flush. And horizontal gray seams must not be less than 90%, vertical gray seams must not be less than 85%, in masonry horizontal and vertical seams must not have blind seams, cracks, transparent seams and so on.

The horizontal mortar joint of the same plane shall be controlled between 11-15mm, and the mortar filling rate shall be high due to the horizontal and vertical mortar joint, and its fullness shall not be less than 80%. When the mortar laying is adopted, the vertical mortar joint shall be constructed by the combination of batching and adding mortar. In the construction, it is strictly forbidden to use water to flush the mortar to fill the joint, and it is not allowed to use stones, wooden wedges and other construction materials to plug the mortar joint for masonry. During masonry, the surface of the mortar joint should be cleaned along with the masonry, so that the masonry height should not be greater than 4 bricks, and the original mortar joint should be flush with the wall in the pointing process. And the horizontal ash joint shall not be less than 90%, and the vertical ash joint shall not be less than 85%. There shall be no blind joint, crack, transparent joint, etc. in the horizontal and vertical joints during the masonry.<br>
