Problems solved by technology

[0007] China invented "the method of using municipal waste incineration ash to burn ecological cement clinker", application number 200410016744.9 discloses a method of using fly ash produced after municipal waste incineration as one of the cement raw materials, and mixing it with commonly used natural cement raw materials. Cement raw meal is burned into cement clinker, and the fly ash is taken from the flue gas dust collector of the waste incineration plant, and the scheme of directly using the waste incineration ash as raw material to produce cement clinker has not been reported yet.

Abstract

The invention relates to an ecologic cement clinker fired through municipal waste incineration ash, and belongs to the technical field of building materials. The ecologic cement clinker is prepared from the following components in parts by weight: 15-82 parts of municipal waste incineration ash, 75-85 parts of sand stone, 20-25 parts of slag, 5-15 parts of yellow sand stone, 2-5 parts of powdered iron, and the balance of water, wherein the municipal waste incineration ash is obtained in a manner that after being crushed, municipal waste is conveyed to a waste incinerator to be subjected to high temperature processing through hot air at the temperature of 850-1250 DEG C to generate cured ash, namely the municipal waste incineration ash; concrete performance tests on cement show that test results of cement mixed concrete produced by mixing the municipal waste incineration ash and cement mixed concrete without the municipal waste incineration ash are similar, but the consumption of natural resources is reduced, so that the cement production cost is reduced, and the sustainable development of cement industries is facilitated.

Description

technical field [0001] The invention relates to an ecological cement clinker, in particular to an ecological cement clinker fired by using municipal waste incineration ash, and belongs to the technical field of building materials. Background technique [0002] Municipal waste refers to the waste generated in urban residents' domestic waste, commercial waste, and municipal maintenance and management. According to statistics, from 1979 to 1996, my country's urban waste increased at an average annual rate of 8.89%. In 1995, the total amount of my country's urban waste was 166 million. At present, the effective treatment rate of domestic waste in my country is only 13%. [0003] With the development of global industrialization and urbanization, environmental problems have attracted the attention of the whole world. In the process of urbanization, urban garbage has sounded the alarm to people. According to different sources of waste generation, urban waste can be divided into th...
