Embodiment 1

[0013] According to ZL200410066443.7, take the fine aggregate from the domestic waste incineration slag; select the incineration slag with the total amount of metals within 1%; and dry the incineration slag to the moisture content within 1%; Coal ash; choose less than 6% of tricalcium aluminate; cement clinker with more than 18% of tetracalcium aluminoferrite; choose gypsum with sulfur trioxide content greater than 45%; crushed to less than 20 mm. With conventional equipment: batching is weighed with a metering belt, air-swept ball mill, silo and conveying equipment are produced through conventional production processes of metering, batching, grinding, inspection and storage for use. Among them, the production control indicators are:

[0014] 1. The fineness of 4900 hole sieve is less than 10%;

[0015] 2. The moisture content is less than 1%;

[0016] 3. The ingredient error is less than 5%.

[0017] Among them, the ratio of raw materials is domestic waste incineration sla...

Embodiment 2

[0019] Other conditions are the same as in Example 1, wherein the ratio of raw materials is: domestic waste incineration slag: fly ash: cement clinker: gypsum=40:30:20:10.

Embodiment 3

[0021] Other conditions are the same as in Example 1, wherein the ratio of raw materials is: domestic waste incineration slag: fly ash: cement clinker: gypsum=40:40:10:10.

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...
