Landscape stone veneer saltpetering-preventing process construction method

Abstract

The invention discloses a landscape stone veneer saltpetering-preventing process construction method. The method is characterized by comprising the following steps that 1, basic layer construction achieves internal solidness and external smoothness, basic layer face elevation construction is in place, smoothness and precision are achieved, only a bonding layer of 2 cm is left, dry and hard cement mortar is prevented from being used, a low-alkaline dedicated bonder is selected, and the bonding layer porosity is reduced; 2, stone is subjected to six-face protection, on the one hand, a protection agent can permeate into the stone to block stone holes, on the other hand, a face layer is subjected to certain water separation protection, and thus a permeating channel of the stone can be closed. The landscape stone facing saltpetering-preventing process construction method has the advantages that compared with the prior art, according to the technical scheme, the water content in a basic layer is reduced, and water in the basic layer is prevented from flowing out. Alkaliferous matter in a bonding layer material is reduced, the thickness of the bonding layer is reduced, and auxiliary materials are saved. The permeating channel of water is effectively closed, saltpetering of the veneer stone is avoided, and the effect of a landscape stone veneer is improved.

Description

technical field [0001] The invention relates to the technical field of landscape engineering, in particular to an anti-efflorescence process for landscape stone veneer. Background technique [0002] The existing decorative stone paving process (wet paste) uses cement mortar as the bonding layer. Both cement and sand in the cement mortar contain alkali substances. The cement and water undergo hydration reactions to form free calcium and other substances, which will After flowing out with water as a carrier and reaching the surface of the stone through the permeation channel, as the water evaporates, these substances remain on the surface of the stone, forming white powder crystals, or reacting with carbon dioxide in the air to form white hard lumps on the surface of the stone. The white substance is commonly known as ubiquinol. [0003] The cement and sand in the cement mortar of the bonding layer contain more alkali substances. [0004] At present, the construction period ...

AI Technical Summary

Problems solved by technology

[0006] There is water outflow in the base layer, alkali substances in the bonding layer, and the existence of permeation channels. These problems are the deficiencies of the existing technology, which directly lead to the efflorescence of the stone veneer.
