Granite concrete pavior brick and its manufacturing method

Abstract

The invention discloses a granite concrete pavior brick and its manufacturing method. The method comprises the following steps: taking cement, mountain sand and broken stone as the bottom layer raw materials, taking cement, mountain sand and granite as the surface layer raw materials, then placing a double-layer die filled with surface layer mixed raw materials and bottom layer mixed raw materials into a 80 ton-110 ton of press machine for vibrating, pressurizing and forming to obtain the granite concrete pavior brick. The granite concrete pavior brick has the advantages of good wear resistance, high strength, uniform bearing, simple and fast construction, good draining performance, low cost and long service life. Comparing the tests under the same usage environment condition and same thickness of the brick, the service life of the granite concrete pavior brick is 2-3 times higher than that of a traditional concrete brick. And can be widely used for large load bearing roads, wharfs, squares, pavements, earth-retaining slopes, lawn roads and the like. Tests prove that the maintenance work is greatly reduced and the manpower and the material resources can be saved by using the pavior brick of the invention.

Description

technical field [0001] The invention relates to a granite concrete pavement brick and a manufacturing method thereof, belonging to the technical field of pavement brick building materials. Background technique [0002] At present, the concrete pavement bricks in the prior art take cement and aggregates as the main raw materials, and are processed, pressurized or other forming techniques to make concrete pavement bricks whose shapes are triangles, squares, or regular hexagons. Concrete pavement bricks are mainly used for laying concrete pavements such as urban roads, sidewalks, and urban squares, as well as blocks and slabs for ground engineering. These concrete paving bricks in the prior art have the following problems: the wear resistance is not good, and the damage rate of the surface is very high under the wear and tear of vehicles such as vehicles; the strength is not high, and edges will appear under the heavy pressure of vehicles such as vehicles; The corner is broken...

AI Technical Summary

Problems solved by technology

These concrete paving bricks in the prior art have the following problems: the wear resistance is not good, and the damage rate of the surface is very high under the wear and tear of vehicles such as vehicles; the strength is not high, and edges will appear under the heavy pressure of vehicles such as vehicles; Broken corners; poor drainage performance, easy to accumulate water

Because the above-mentioned problems exist in the concrete pavement brick in the prior art, so its use effect is not ideal enough yet
