High-temperature-resisting cement mortar cloth

Abstract

The invention discloses high-temperature-resisting cement mortar cloth. The high-temperature-resisting cement mortar cloth comprises outer-layer cloth, body-layer cloth and inner-layer cloth, whereinthe outer-layer cloth and the inner-layer cloth both comprise warp yarns and weft yarns which are interwoven with each other; the body-layer cloth comprises warp yarns and weft yarns which are interwoven with each other as well as connecting silks connected with the outer-layer cloth and the inner-layer cloth; the warp yarns are all or partial high-temperature-resisting composite yarns or / and theweft yarns are all or part of high-temperature-resisting composite yarns or / and the connecting silks are all or part of high-temperature-resisting composite yarns; a space defined by the interwoven warp yarns and weft yarns of the body-layer cloth is filled with high-temperature-resisting cement mortar powder; the high-temperature-resisting cement mortar body at least comprises a high-temperature-resisting water hard cementitious material. The high-temperature-resisting cement mortar cloth has the advantages of rapid construction, energy conservation, environmental protection, good toughness and excellent high temperature resistance.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a high-temperature resistant cement mortar cloth. Background technique [0002] Cement-based building materials in the traditional sense generally need to be mixed and formed on site, or transported to the site through commercial concrete or mortar mixing stations. Either way will generate a lot of dust through mixing, and it is necessary to add a large amount of additives to ensure the slurry When the slurry is transported to the site, it needs to be constructed through corresponding construction processes, such as vibrating, spraying, plastering, etc. These processes consume a lot of manpower and material resources as well as time costs. [0003] Although cement-based building materials have good compressive strength, their flexural or tensile strength is relatively low. In the prior art, adding toughening components to the system can improve it to some extent, but the effect ...

[0002] Cement-based building materials in the traditional sense generally need to be mixed and formed on site, or transported to the site through commercial concrete or mortar mixing stations. Either way will generate a lot of dust through mixing, and it is necessary to add a large amount of additives to ensure the slurry When the slurry is transported to the site, it needs to be constructed through corresponding construction processes, such as vibrating, spraying, plastering, etc. These processes consume a lot of manpower and material resources as well as time costs

[0003] Although cement-based building materials have good compressive strength, their flexural or tensile strength is relatively low. In the prior art, it can be improved by adding toughening components to the system, but the effect is not significant

At the same time, the high temperature resistance of traditional cement-based building materials is not good, and some hydration products are easy to decompose under high temperature conditions, resulting in a decrease in strength.
