Problems solved by technology

The existing pointing materials have poor water permeability and cannot effectively drain the moisture in the masonry cultural relics buildings in humid areas, causing the wall or rock mass to be in a wet state for a long time, affecting the stability of the structure. At the same time, the existence of a large amount of water gives Vegetation provides good growth conditions, resulting in many bryophytes appearing on the surface of the building, which affects the appearance

Abstract

The invention discloses a permeable pointing agent composition which consists of the following components in percentage by weight: 60-79 percent of aggregate, 20-39 percent of natural water hard limeand 1-2 percent of an auxiliary. The invention further discloses a preparation method of the permeable pointing agent composition. The permeable pointing agent composition prepared through the preparation method disclosed by the invention has good water permeability and can effectively drain moisture in brick and stone heritage buildings in a wet area and avoid the influence on the stability of astructural body as a wall body or a rock mass is in a damp state for a long time; moreover, as the surfaces of the buildings are no longer damp, the appearance of many bryophytes on the surfaces of the buildings is also avoided, therefore, the attractive appearances of the surfaces of the buildings are ensured.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a water-permeable pointing agent composition and a preparation method thereof. Background technique [0002] Pointing materials are also called caulking agents and grouting agents, which are mainly used for caulking between tiles, tiles, marble, granite and other bricks. The existing pointing materials have poor water permeability and cannot effectively drain the moisture in the masonry cultural relics buildings in humid areas, causing the wall or rock mass to be in a wet state for a long time, affecting the stability of the structure. At the same time, the existence of a large amount of water gives Vegetation provides good growth conditions, resulting in many bryophytes appearing on the surface of the building, which affects the appearance. Contents of the invention [0003] The object of the present invention is to provide a water-permeable pointing agent composit...
