Ashlar brick and preparation method thereof

Abstract

The invention relates to an ashlar brick. A preparation method for the ashlar brick comprises the following concrete steps: 1) weighing 280 parts of medium sand with a particle size of 2.5 mm, 150 parts of fine sand with a particle size of 1.25 mm and 170 parts of lime rock cuttings with a particle size of 0.5 mm and carrying out uniform mixing; 2) adding 150 parts of Po42.5 cement and carrying out stirring; 3) adding 50 parts of water and carrying out complete stirring for 5 min; 4) carrying out extruding by using hydraulic pressure equivalent to 10 tons and carrying out vibration with a 98-KN vibration machine; and 5) carrying out maintenance for 7 days, then carrying out polishing by using a stripe machine and carrying out polishing and molding when striature occurs on a surface and a stone surface is exposed. The ashlar brick prepared by using the method has the advantages of a high grade, high strength, neat appearance, a good ashlar effect, antiskid performance, durability, no peeling at all, no surface shedding, etc.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a stone-like brick and a preparation method thereof. Background technique [0002] Pavement bricks are a common building material with a large amount of consumption. There are mainly two types in the market, one is natural and the other is man-made. The marble paved with natural pavement bricks is granite, which is a non-renewable resource. , but due to excessive mining, the ecological balance has been seriously damaged. Artificial pavement bricks are concrete pavement bricks and imitation stone striped bricks, both of which are made of two different materials, the surface layer and the main body. Although artificial pavement bricks save a lot in cost, they are basically Within two years, there will be phenomena such as losing face and falling off, which will cause a waste of financial and human resources in disguise. Therefore, it is imperative to develop a new type of imitat...
