Problems solved by technology

[0002] At present, construction concrete waste accounts for about 40% of construction waste, and waste concrete powder accounts for 25% of waste concrete. It can be seen that the amount of waste concrete powder is large, but the amount that can be reused is very small
The main part of the waste concrete powder is sent to the landfill, and the landfill will not only occupy a large amount of land, but also pollute the soil and air

Abstract

The invention discloses a ceramic glaze prepared from waste concrete powder and a preparation method of the ceramic glaze. The ceramic glaze consists of the following components in parts by weight: 30-50 parts of feldspar powder, 15-30 parts of quartz powder, 3-10 parts of kaolin, 30-50 parts of glaze stone powder, 6-50 parts of a mixture of waste concrete powder and glass powder, 4-12 parts of talcum powder and 2-5 parts of ZnO. The ceramic glaze prepared from the waste concrete not only can solve a problem on handling construction waste but also can achieve the recycling of the construction waste. By virtue of the ceramic glaze prepared by the invention through the waste concrete powder, the additional value of recycling the waste concrete can be greatly improved, and the thought of recycling the waste concrete is widened. The method is applicable to the preparation of the ceramic glaze, and is capable of achieving the recycling of the construction waste; and since the waste concrete powder is high in quantity and low in cost, the quantity of natural resources adopted by the ceramic glaze can be reduced.

Description

technical field [0001] The invention belongs to the field of recycling of construction waste, and in particular relates to a ceramic glaze prepared from waste concrete powder and a preparation method thereof. Background technique [0002] At present, construction concrete waste accounts for about 40% of construction waste, and waste concrete powder accounts for 25% of waste concrete. It can be seen that there is a large amount of waste concrete powder, but the amount that can be reused is very small. The main part of the waste concrete powder is sent to the landfill, and the landfill will not only occupy a large amount of land, but also pollute the soil and air. At the same time, in the preparation of building ceramics, etc., a large amount of natural sand and gravel needs to be consumed every year. Waste concrete powder can generate wollastonite in large quantities at temperatures above 1100°C after composition adjustment, so it can be used instead of wollastonite to prepa...
