Courtyard anti-saltpetering paving structure and using method thereof

Abstract

The invention belongs to the field of garden architecture decoration, and concretely discloses a courtyard anti-saltpetering paving structure and a using method thereof. The courtyard anti-saltpetering paving structure includes a finish block layer, a low-alkali cement layer, a crushed rock layer, a leveling layer and a compacted base layer. The finish block layer and the low-alkali cement layer are connected to each other through an adhesive layer. The upper end of the finish block layer is coated with a hydrophobic coating layer, A gravel layer is arranged between the crushed rock layer andthe leveling layer. Water pipes are laid inside the gravel layer. The ends of the water pipes communicate with a main drainage pipe. A geotextile layer is arranged between the leveling layer and the compacted base layer. A manufacturing material of the adhesive layer in the courtyard anti-saltpetering paving structure is an epoxy resin adhesive. The characteristics of the epoxy resin adhesive aresmall volume shrinkage and strong cementation strength and corrosion resistance. The adhesive layer improves the waterproof performance of the courtyard anti-saltpetering paving structure and furtherimproves the anti-saltpetering performance of the courtyard anti-saltpetering paving structure.

Description

technical field [0001] The invention relates to the field of garden building decoration, in particular to a courtyard anti-pan-alkaline pavement structure and a use method thereof. Background technique [0002] Ordinary concrete is silicate. When it encounters air or water vapor in the wall, the silicate ion undergoes a hydrolysis reaction, and the generated hydroxide combines with metal ions to form a hydroxide with low solubility. When the temperature rises, the water As the steam evaporates, the hydroxide is precipitated from the wall. With the gradual evaporation of water, the hydroxide is precipitated on the surface of the concrete and cement. Over time, the original decorative paint or paint is lifted up and no longer adheres to the wall. On the surface, whitening, peeling, and shedding occur. This process is called efflorescence. [0003] In landscape engineering, it is often seen that a layer of white substance appears on the surface of concrete, sintered bricks, sl...
