Solidification material prepared from incineration residue material as well as production method and application thereof

Abstract

The inventon provides a solidification material prepared from incineration residue material as well as a production method and application thereof. The solidification material is prepared by the following components in percentage by weight: 30-40 percent of domestic garbage incineration residue, 30-40 percent of pulverized fuel ash, 10-20 percent of cement clinker, and 5-10 percent of gypsum, wherein the selected incineration residue contains metal objects, the total mount of which is within 1 percent, and is dried to have moisture within 1 percent, the selected pulverized fuel ash contains high-calcium ash and moisture which are both within 1 percent; the selected cement clinker contains tricalcium aluminate and tetracalcium aluminoferrite the contents of which are respectively with 6 percent and above 18 percent; and the selected gypsum contents sulfur trioxide, the content of which is more than 45 percent, and are smashed to below 20 mm. The invention can be used as the solidification material for a road surface subbase course material.

Description

Technical field: [0001] The invention provides a solidification material prepared from incineration slag material and a production method and application of the solidification material. Background technique: [0002] With the development of urbanization, a large number of urban populations are producing more and more municipal solid waste every month and every day. For the growing urban solid waste every year, in addition to filling it up, it is to take incineration to deal with it. And domestic waste incineration is one of the more advanced disposal methods at present. After incineration and disposal of waste, a certain amount of residue will be produced - incinerator slag. At present, Shanghai alone produces 14,000 tons of domestic waste every day. Calculated by calculating 0.22 tons of slag per ton of waste, the city of Shanghai will produce 3,000 tons of slag every day. Therefore how to effectively utilize these incineration slags is an urgent technical problem to be s...

[0003] On the other hand, in road construction, a large number of cement-stabilized ingredients are used as the pavement base material. The material uses cement as the coagulant. Special requirements, but there is no completely suitable cement variety in the existing cement series standards, which affects the processing and use of this material

Specifically, the existing cement has a short setting time, and in addition, the existing cement has high strength. Therefore, when used as a roadbed material, in order to prevent thermal expansion and contraction stress changes, it is necessary to adjust the ratio of materials, processing, and A series of measures are taken in various process links such as construction to prevent
