Abstract

The invention provides a stone pavement anti-efflorescence method. The stone pavement anti-efflorescence method comprises the following steps: (1) cleaning stones, and naturally air-drying or drying the stones; (2) adding water in a bonding material which is composed of low-alkali cement, bentonite, rosin resin, redispersible powder, cellulose ether, water repellent and water reducing agent, and adding the mixture in a grinding machine for high-speed stirring so as to obtain stone glue; (3) paving after mixing the stones and the stone glue uniformly and at a low speed in a mixer, and firmly sealing stone gaps by using the stone glue; (4) after the pavement, painting a waterproof agent on the whole surfaces of the stones. The raw materials of the stone pavement anti-efflorescence method are rational in formula, good in compatibility, relatively low in cost and nontoxic; the pavement technology is simple and easy to operate; the path leading to efflorescence of the stones can be well cut off, and products such as Ca(OH)2 and salts and water invasion are reduced, so that the stones have no efflorescence phenomenon for a long time. Procedures and expense for later maintenance are reduced.

Description

technical field [0001] The invention belongs to the field of stone pavement, in particular to a stone pavement anti-efflorescence method. Background technique [0002] Stone is the most widely used material in landscape engineering or architectural engineering. Stone has been used more and more widely because of its solid texture, various shapes and beautiful colors. Stone has become an indispensable material in garden design and construction industry. Because stone is composed of various minerals, its stability is very poor, and it is very easy to chemically react with other chemical substances. The most common phenomenon is "pan-alkali". Its performance is that in landscape engineering or construction engineering, after the stone plate is paved for a period of time, there will be plaques similar to "watermarks". As the inlaid mortar hardens and dries, the "watermarks" will shrink slightly. Some even disappeared, and they appeared isolated and scattered in the plates. How...
