Problems solved by technology

[0003] (1) Use the method of adding surface retarder to wash the surface after the bottom layer is hardened. This method needs to wait for the bottom layer to harden. The construction interval is long and the efficiency is low. The strength of the permeable board (brick) is low, and the spraying is too little, and the slurry on the surface aggregate cannot be washed away, which will affect the appearance of the surface;
[0004] (2) The color permeable board (brick) prepared by adding pigments is not durable in long-term outdoor use environment, and is easy to be worn, and the aggregate and color on the surface are easy to fall off, which affects the appearance of the surface layer;
[0005] (3) Colored permeable panels (bricks) prepared with organic adhesives, on the one hand, will cause environmental pollution due to the volatility of organic materials; The aesthetic effect of the surface layer

Abstract

The invention belongs to the field of building materials, and in particular relates to a high-strength water-permeable stone plate and a preparation method thereof. The high-strength water-permeable stone slab provided by the present invention is formed by mixing and pressing various raw materials, and the raw materials include cement, aggregate, and reinforcing agent in specific weight parts; wherein the cement is selected from Hunter whiteness > 70 and strength grade not less than 42.5 Silicate or sulphoaluminate cement; reinforcing agents include limestone powder, vitrified microbeads, mineral powder, thickener, powder polycarboxylate water reducer, coagulation regulator and quartz sand in specific proportions. The colored stone board is formed by pressing and curing after adding a specific reinforcing agent. It does not need to add a surface retarder. The production efficiency is high, and it can improve the wrapping uniformity of the slurry and the aggregate. The grinding performance is better.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a high-strength water-permeable stone plate and a preparation method thereof. Background technique [0002] Permeable panels (bricks) have good water permeability and excellent mechanical properties, and are widely used. In addition, the state and the municipal government have vigorously promoted the construction of sponge cities, which has also increased the use of permeable panels (bricks), and the application of permeable panels (bricks) in garden landscape principles is more common. In order to increase the decoration, permeable panels (bricks) are often made into different colors. Existing color permeable panels (bricks) are generally prepared with aggregates, organic binders, and pigments, poured into shapes, and then sprayed with a retarder on the surface, and the surface is rinsed after the bottom is hardened, so that the color effect of the aggregates can b...
