Construction residual mud pavement brick and preparation method thereof

Abstract

The invention discloses a construction residual mud pavement brick and a preparation method thereof, wherein the construction residual mud pavement brick comprises the following raw materials by weight: 20-60 parts of a construction residual mud material, 10-35 parts of aggregate, 0.2-1 part of a curing agent, 8-15 parts of cement, and 10-30 parts of water, wherein the construction residual mud material is construction residual mud having a particle size of 0-5 mm and obtained by dehydrating, crushing, screening and impurity removing. The method comprises the following steps: uniformly mixingand stirring construction residual mud, aggregate, cement, a curing agent solution and water to obtain a mixed slurry, performing compression molding treatment on the mixed slurry to obtain molded bricks, and performing maintenance treatment on the bricks under the conditions of normal temperature and humidity of 90-95%. By implementing the method, under the condition of realizing the same productquality, the cost is reduced, the waste utilization is realized, the natural resources are saved, the environment is protected, and the cyclic regeneration economy is formed.

Description

technical field [0001] The invention relates to the technical field of pavement bricks, in particular to a pavement brick prepared by using building mud as a raw material and a method thereof. Background technique [0002] Construction waste is the main component of urban waste, accounting for about 30%-40% of the total urban waste. Among them, the residual mud content accounts for more than 40%. In 2004 alone, my country produced about 6 billion tons of construction waste. By 2020, my country will add about 30 billion square meters of construction area, and the newly generated construction waste will be a shocking figure. At present, the construction mud can only be treated by dehydration, and then the traditional open-air stacking and landfill are the main methods. At present, there is no room for accommodation. At the same time, this method is expensive, consumes a lot, occupies a lot of land resources, and produces huge waste. environmental pollution. If such a large ...

[0004] Therefore, although the disposal of garbage by burial is large, convenient and simple, and the disposal cost is low, it actually occupies a large amount of land resources and causes irreversible environmental pollution.

If such a large amount of construction waste cannot be recycled in time, it will not only pollute the environment, but also cause a serious waste of resources.

[0005] On the other hand, with the acceleration of the urban process and the continuous improvement of people's aesthetic methods, pavement bricks are widely used in the construction of modern towns, and various pavements, parking lots, squares, green belts and other places are laid. Pavement bricks, while ordinary pavement bricks are made of natural sand and gravel as raw materials, which not only consumes a lot of natural resources, but also brings huge ecological damage during the mining process, which has a huge impact on the ecological environment
