(2) When the interface agent layer is in a slurry state, a semi-dry slurry I containing dry-hard cement mortar is laid for manual fine leveling, and the surface is moistened by spraying water. The amount of semi-dry slurry I is controlled to form a dry-hard cement mortar layer with a thickness of 40 mm; the water content of the surface of the dry-hard cement mortar layer is 14 wt%. The specific steps for manual fine leveling are as follows: S1. Making wet reinforcement: Using the thickness of the dry-hardened cement mortar layer as a reference, compact and smooth a portion of the semi-dry mortar I to create the reinforcement reference. Specifically: Two wet reinforcing bars with an average width of 25cm are installed at the base of the wall.

[0057] Example 2 (1) Remove the accumulated dust, laitance, oil stains and debris from the cement mortar base surface. After wetting the surface with water 24 hours in advance, apply interface agent II to the cement mortar base surface and control the amount of interface agent II to form an interface agent layer with a thickness of 1.8 mm. (2) When the interface agent layer is in a slurry state, a semi-dry slurry I containing dry-hard cement mortar is laid for manual and machine fine leveling, and the surface is moistened by spraying water. The amount of semi-dry slurry I is controlled to form a dry-hard cement mortar layer with a thickness of 40 mm; the moisture content of the surface of the dry-hard cement mortar layer is 15 wt%. a. Create a reference starting platform: Lay the semi-dry slurry I onto the base surface of the machine construction starting point, tamp it down, scrape it flat, and rub it evenly. Use a level laser instrument to create a starting platform no smaller than the size of the leveling machine, based on the thickness of the dry hard cement mortar layer. b. Machine leveling construction: Starting from the starting platform, lay dry hard cement mortar semi-dry slurry I according to the machine leveling path. The thickness of semi-dry slurry I is 10mm higher than the starting platform. Lift the machine to the starting platform, adjust the machine leveling benchmark, set the machine laser position and the thickness of the dry hard cement mortar layer, and then start the machine leveling construction to obtain the machine-completed layer. c. Surrounding leveling: Manual fine leveling is carried out in areas where the machine cannot work. The thickness of the layer completed by the machine is used as a benchmark. The layer is compacted, scraped, and rubbed evenly. (3) Spread wear-resistant aggregate semi-dry on the upper surface of the dry hard cement mortar layer (first use a continuous mixer to mix the wear-resistant aggregate into a non-agglomerated powder slurry with a moisture content of 5% by adding water, and then carry out the semi-dry spreading operation), and then grind and finish the surface; The specific operation of grinding and finishing the surface is as follows: First, use a grinding equipment (with a grinding disc) to grind the surface smooth. Then, use a grinding equipment (with inclined blades) to grind and eliminate defects such as surface holes and roughness. When the surface of the wear-resistant aggregate material has initially set after the water has evaporated, use the grinding equipment (with inclined blades) to finish the surface again. (4) After hardening, use diamond grinding discs to rough grind the surface, control the amount of material used to form the wear-resistant aggregate layer to form a wear-resistant aggregate layer with a thickness of 4mm, then apply a curing agent to the upper surface of the wear-resistant aggregate layer, control the amount of curing agent used to form a curing agent layer with a thickness of 0.2mm, and then grind and polish to obtain the wear-resistant floor.

[0058] Example 3 This embodiment uses a method similar to that of Embodiment 1, except that: interface agent I in step (1) is replaced with interface agent III; all parts not listed are the same as in Embodiment 1.

[0059] Example 4 This embodiment uses a method similar to that of Embodiment 1, except that: semi-dry slurry I in step (1) is replaced with semi-dry slurry II; all parts not listed are the same as in Embodiment 1.

[0060] Comparative Example 1 (1) Base cleaning: Remove debris and oil stains from the concrete base surface to ensure it is clean and dry; (2) Pouring fine stone concrete layer: Pour M25 fine stone concrete, vibrate and level the concrete with a laser leveling machine; before initial setting, use a slurry lifting machine to lift the slurry and remove air bubbles, so that the slurry is evenly distributed on the concrete surface, which is convenient for subsequent aggregate bonding; control the amount of M25 fine stone concrete to form a concrete layer with a thickness of 100mm. (3) Set up the wear-resistant aggregate layer: When the concrete layer has initially set to the point where there is no obvious indentation when pressed with a finger (only fingerprint), spread the wear-resistant aggregate for the first time (the first spread should be 2 / 3 of the total mass of wear-resistant aggregate, spread evenly to avoid accumulation, and manually add it to the corner areas); use a disc trowel to grind at low speed so that the wear-resistant aggregate is completely embedded in the concrete surface until the wear-resistant aggregate and concrete slurry are fully integrated and there are no obvious aggregate particles on the surface; After the first layer of wear-resistant aggregate is completely wetted, a second layer is applied (the remaining 1 / 3 of the wear-resistant aggregate is applied). The above grinding and slurry-raising process is repeated to ensure that the surface layer is uniform and dense. After the quartz sand is fully embedded, a disc power trowel is used to grind at medium speed to further raise the slurry and compact it, eliminating surface color differences and wear-resistant aggregate accumulation marks. Before the concrete sets, the blade power trowel is replaced with a high-speed grinding and polishing machine to form a dense and smooth wear-resistant aggregate layer on the ground surface. Control the total mass of wear-resistant aggregate to form a wear-resistant aggregate layer with a thickness of 5 mm; (4) After the wear-resistant aggregate layer has been cured and hardened, rough grinding is performed. Then, a curing agent is applied to the upper surface of the wear-resistant aggregate layer. The amount of curing agent is controlled to form a curing agent layer with a thickness of 0.3 mm. Then, the surface is ground and polished to obtain the wear-resistant floor.

[0061] Comparative Example 2 This comparative example was carried out using a method similar to that of Example 1, except that the semi-dry slurry I in step (1) was replaced with semi-dry slurry DI-1; all other parts not listed are the same as in Example 1.

[0062] Test case The following tests were performed on the above embodiments and comparative examples: 1. Test method for surface pull-out strength of wear-resistant aggregate layer: The pull-out method is adopted, and three measuring points are selected to test the strength using a special pull-out instrument.

[0063] 2. Pull-out strength (MPa) between dry-hardened mortar layer or fine aggregate concrete layer and base layer: The pull-out method is used. Three measuring points are selected, and the base layer is cut 3-5mm away. The pull-out strength of the bonding layer is tested with a special pull-out instrument. 3. Surface compressive strength of wear-resistant aggregate layer: The compressive strength of concrete was measured using a concrete rebound hammer, referring to the method specified in JGJ / T 23-2011 "Technical Specification for Testing Compressive Strength of Concrete by Rebound Method". 4. Test method for surface flatness after leveling with dry-hardened cement mortar / fine aggregate concrete: The flatness is measured using a 2m straightedge and a wedge gauge.

[0064] 5. Mohs hardness test method: Use a Mohs hardness pen to scratch the surface; The test results are shown in Table 1: Table 1

[0065] Note: For example, "the surface flatness after leveling is 3mm / 2m" means that within any 2-meter range, the height difference (i.e., drop) between the highest and lowest points of the measured object surface (such as the ground, wall, countertop, etc.) does not exceed 3 millimeters.

[0066] The results above show that the construction method provided by this invention has high leveling accuracy; and the wear-resistant aggregate can be applied immediately with a short overall curing period, which significantly reduces the construction cycle.

[0067] The preferred embodiments of the present invention have been described in detail above; however, the present invention is not limited thereto. Within the scope of the inventive concept, various simple modifications can be made to the technical solutions of the present invention, including combinations of various technical features in any other suitable manner. These simple modifications and combinations should also be considered as the content disclosed in the present invention and are all within the protection scope of the present invention.
