Environment-friendly pavement brick and manufacture method thereof

Abstract

The invention belongs to the technical field of energy-saving building materials, and provides an environment-friendly pavement brick and a manufacture method thereof. The environment-friendly pavement brick is prepared from the following raw materials in parts by weight: 20-25 parts of kieselguhr, 16-29 parts of gypsum powder, 25-46 parts of a concrete compound, 4-5 parts of coal ashes, 1-3 parts of ceramic wastes, 5-11 parts of shell powder, 9-14 parts of mortar, 11-15 parts of sweet potato straws, 1-6 parts of magnesium sulfate, 2-5 parts of a stabilizer and 1-2 parts of a binder, wherein the concrete compound is prepared from recycled concrete aggregates and waste fibers. According to the environment-friendly pavement brick, the problems that an existing pavement brick is low in compressive strength, poor in heat preservation and heat insulation properties and high in energy consumption are solved.

Description

technical field [0001] The invention belongs to the technical field of energy-saving building materials, in particular to an environment-friendly pavement brick and a preparation method thereof. Background technique [0002] Building energy conservation is an important part of implementing the sustainable development of the national economy. In 1970, energy consumption for buildings was 10% of the gross national value. During 1988-2006, energy consumption increased at a rate of 5.6% per year. By 2006, it had grown to 25% of the gross national value. By 2020 , energy consumption for buildings may be 35% of the total GNP. Therefore, in order to achieve sustainable development of the national economy, it is imperative to implement building energy conservation. [0003] As a paving material, pavement bricks have a wide range of applications, and the consumption of daily raw materials is correspondingly huge. It is urgent to find other alternative materials to save the developm...
