[0002] Question 1: Ceramics are consumables widely used in the field of production and life
For example, take Jinjiang City as an example. It is a major ceramic production area. In 2008, the local average daily output reached more than 200 tons. Waste ceramics cannot be effectively used and dumped everywhere, which has seriously damaged the appearance of the local town and hindered local construction.
[0003] Question 2: The filter material mainly composed of diatomite (a large amount) and expanded perlite (a small amount) is widely used in the filtration process of food production and processing enterprises, and it is also a large amount of consumables

Example Embodiment
[0049] The preparation method of photocatalyst ecological brick includes the following steps:
[0050] A. After cleaning up the impurities of the waste ceramics, then crush them into ceramic scraps. Further, the particle diameter of more than 90% of the ceramic scraps in step A is 0.2 cm -0.5 cm. Appropriately permitted, 0-5% of large particles with a particle diameter of 0.5 cm-1.0 cm and 0-5% of powder with a particle diameter of 0.2 cm or less are present in the ceramic scrap.
[0051] B. Dry the waste filter material whose main components are diatomaceous earth and expanded perlite, and then screen out coarse filter material regenerated material and fine filter material regenerated material. Further, the drying treatment method of the waste filter material in step B is sun drying or drying. The sieving treatment method of the waste filter material in step B is sieving with the boundary of 0.2cm-0.5cm. After sieving, the waste filter material below 0.2cm is the fine filter me...

Abstract
The invention relates to a building material preparation process, in particular to a preparation process for brick substrates such as pervious bricks or floor bricks or concrete building blocks and the like. A method for preparing photocatalyst ecological bricks comprises the following steps that: A, waste ceramic impurities are crushed into crushed ceramic materials after being cleaned; B, wastefilter materials with main ingredients of diatomite and expanded perlite are dried, and then, rough filter material regenerated materials and fine filter material regenerated materials are sieved; C,the crushed ceramic materials and the rough filter material regenerated materials which are obtained in the steps A and B are mixed with ordinary portland cement and water and are stirred into dry concrete according to certain mass parts, the dry concrete is made into brick substrates, then, the fine filter regenerated materials, sand or stone dust, mineral pigment, white cement, nanometer titanium dioxide powder and water are mixed and stirred to be made into plus materials of the brick substrates, and the plus materials and the brick substrates are simultaneously pressed and formed; and D, the photocatalyst ecological bricks obtained in the step C are cured until the design strength is reached.
Description
technical field [0001] The invention relates to a preparation process of building materials, in particular to a preparation process of permeable bricks or floor bricks or concrete blocks and similar brick substrates. Background technique [0002] Question 1: Ceramics are consumables widely used in the field of production and life. In recent years, the pollution of waste ceramics produced in the production of building ceramics to the environment has become increasingly serious. According to statistics, since 1997, waste ceramics has been increasing at a rate of 12%-20% every year. For example, take Jinjiang City as an example. It is a major ceramic production area. In 2008, the local average daily output reached more than 200 tons. Waste ceramics cannot be effectively used and dumped everywhere, which has seriously damaged the appearance of the local town and hindered local construction. . [0003] Question 2: The filter material mainly composed of diatomite (a large amou...
