A kind of concrete pavement brick and preparation method thereof

Abstract

The invention provides a concrete pavement brick and a preparation method thereof. The concrete pavement brick comprises the following raw materials: sand, stones, cement, water and a water reducing agent; wherein the sand comprises granite sand prepared by granite and common sand used for preparing the pavement brick; the particle size of the granite sand is 0.075-0.150 mm; the stones comprises granite stones prepared by the granite and common stones used for preparing the pavement brick; the particle sizes of the granite stones are 5-9.5 mm; the cement comprises granite fine powder preparedby the granite and common cement used for preparing the pavement brick; and the particle size of the granite fine powder is small than 0.075 mm. The concrete pavement brick provided by the invention belongs to an environmental-protection ecological type concrete brick and has the characteristics of being free from baking, good in strength, and the like.

Description

technical field [0001] The invention relates to the technical field of engineering, in particular to a concrete pavement brick and a preparation method thereof. Background technique [0002] my country has a vast territory, and granite stones are widely distributed, and the demand has always been high. Especially in the past 40 years of reform and opening up, with the rapid development of my country's economy, the demand for granite stones is also increasing, and the output of granite stones is also increasing. From the previous hundreds of thousands of square meters to the current nearly one billion square meters, the granite is hard, and a large amount of stone waste will be generated during the mining process. Saving resources and protecting the environment has always been a basic national policy of our country, and the implementation of this basic national policy plays a vital role in promoting the construction of a resource-saving and environment-friendly society. The "...
