Durable pavement brick and preparation process thereof

Abstract

The invention discloses a durable pavement brick including a surface layer and a bottom layer, the surface layer comprises the following components by weight: 20-30 parts of granite; 5-10 parts of latex powder; 3-8 parts of silica fume; 10-20 parts of cement; 1-2 parts of a water reducer and 5-8 parts of potassium feldspar powder; and the bottom layer comprises the following components by weight: 25-40 parts of quartz sand; 10-25 parts of coal gangue; 15-30 parts of cement; 1-2 parts of and polypropylene fiber and 2-3 parts of the water reducer. The invention discloses a preparation process of the durable pavement brick, and the preparation process comprises the following steps: a), surface layer material first mixing; b), surface layer material second mixing; c), surface layer making; d) bottom layer material mixing; e) bottom layer making and f) surface treatment. The prepared durable pavement brick is strong and durable, the surface is not easy to be worn, and not susceptible to corrosion weathering, the durable pavement brick can maintain in a long-term good condition on a road without frequent replacement, and the road is more suitable for walking; raw materials are simple, the durable pavement brick is convenient to manufacture, production efficiency can be effectively improved, and the cost can be reduced.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of brick making, in particular to the technical field of durable pavement bricks and a preparation process thereof. [0003] 【Background technique】 [0004] Pavement bricks are used for laying concrete pavements of urban road sidewalks, city squares, and blocks and slabs of ground works. The existing pavement bricks are easily damaged and easily corroded, and cannot meet the demand well. [0005] [Content of the invention] [0006] The purpose of the present invention is to solve the problems in the prior art, and to propose a durable pavement brick and a preparation process thereof, which can make the pavement brick durable. [0007] In order to achieve the above object, the present invention proposes a durable pavement brick, comprising a surface layer and a bottom layer, and the surface layer is composed of the following components in parts by weight: [0008] 20-30 servings of granite; [000...
