A porous concrete road surface structure made from polymer modified cement and a construction method thereof are disclosed. The structure successively comprises a bottom layer, a bonding layer, a porous concrete layer and a surface treatment layer. The bonding layer is located on the bottom layer, and the porous concrete layer on the bonding layer is prepared through paving, leveling and jolting a composition mixed from broken stone, sand and a slurry mixture of polymer modified cement. The addition of polymer promotes bonding of granular materials with the slurry mixture tightly, the use of the bonding layer makes the road surface structure and the bottom layer form an integral body, and the road surface structure has high strength, good crack resistance, water resistance, ageing resistance and corrosion resistance; the use of an intermittent or single graded of particles results in large pores, makes the road surface water-penetrating, decreases noise and amount of the polymer; and, the surface treatment can improve markedly surface properties and its use according to the application can make the porous concrete layer has rigid or flexible characteristic. The porous concrete road surface can be paved, leveled and jolted by paving machine or manual labor.

The invention discloses an imprinted water-permeable cement concrete ground structure with aggregate exposed on the surface. The structure comprises components of, from top to bottom: a cement water-permeable concrete layer, a bedding layer and a base layer. The layers are orderly arranged from top to bottom. Patterns and textures are formed through an imprinting technology on the upper surface of the cement water-permeable concrete layer with an aggregate exposure effect, wherein the cement water-permeable concrete layer is the top layer. The manufacturing method of the ground structure comprises steps that: (1) the base layer is paved; (2) the bedding layer is paved on the base layer; (3) at least one cement water-permeable concrete layer is paved on the bedding layer; (4) the patterns and textures are formed through imprinting on the surface of the top cement water-permeable concrete layer; (5) an aggregate exposure treatment is carried out upon the surface of the imprinted top cement water-permeable concrete layer. The aggregate exposure treatment comprises specific steps that: a surface-setting-retarding material is sprayed on the surface of the imprinted top cement water-permeable concrete layer, or a cement-setting-retarding film is coated on the surface of the imprinted top cement water-permeable concrete layer, then the surface of the imprinted top cement water-permeable concrete layer is washed; or the surface of the imprinted top cement water-permeable concrete layer is directly washed, such that the aggregate exposure effect is realized. The method also comprises a step (6), which is a maintenance step. The imprinted water-permeable cement concrete ground structure with the aggregate exposed on the surface is both an environment-friendly ground structure and a decorative ground structure.

The invention discloses a floor slab with a decorative surface protection layer. The floor slab is made by a manufacturing method comprising the following process steps of paving; concrete vibrating, leveling and punning; maintaining; coarse grinding the surface of a floor slab layer to remove a laitance surface layer; forming a compact layer, wherein concrete repair solution and powder ground from the coarse grinding step are mixed; forming a strengthened layer, wherein concrete enhancer is downwards permeated for 3mm-5mm from the surface of the compact layer, and the concrete enhancer and concrete are reacted to form the strengthened layer; fine grinding and polishing; forming a protection layer, wherein permeation solution is applied to the strengthened layer and is permeated downwards, and the permeation solution and the concrete are reacted to form the protection layer. According to the floor slab with the decorative surface protection layer provided by the invention, materials can be at least saved, the overall anti-pressure ability of the floor slab layer is improved, the load and the construction cost of buildings are reduced, and meanwhile, the environment can be protected.
