Domestic garbage prefabricated part and method of manufacturing the same

Abstract

The invention provides a living garbage precast part and a manufacture method thereof; wherein, the materials of the living garbage precast part comprise: 36 to 57 wt percent of living garbage cinder, 5 to 14 wt percent of cement, 24 to 47 wt percent of scree, 0 to 8 wt percent of construction sand, 0 to 4 wt percent of fly ash, 0 to 0.5 wt percent of silicon ash, 0 to 0.2 wt percent of concrete admixture, as well as 5 to 9.5 wt percent of water. The living garbage precast part provided by the invention can replace a concrete precast part and become the construction materials with higher intensity like ground tiles, building blocks or road edge stones, realizes the innocent treatment of the living garbage with lower cost, and has excellent economic and social benefits. The invention also provides a manufacture method for the living garbage precast part, which prepares the living garbage precast part of the invention by the steps of mixing, shaping, maintaining, and the like.

Description

technical field [0001] The invention relates to a concrete prefabricated part produced by using garbage incineration slag, in particular provides floor bricks and blocks made of the concrete, and belongs to the field of green building material manufacturing. Background technique [0002] With the rapid development of the economy, the rapid improvement of people's living standards, and the continuous acceleration of the urbanization process, the amount of urban waste generated in my country has increased sharply, and the growth momentum remains unabated. At present, the annual output of urban garbage in my country has reached 140 million tons, and the per capita garbage output is about 450-500 kg, which is still increasing at an annual growth rate of 8-10%. In order to better deal with the increasing amount of domestic waste and solve a series of problems caused by traditional waste disposal methods, the treatment of domestic waste in my country is transitioning to harmless t...

Problems solved by technology

[0004] China Patent No. 98125624.4 (authorized announcement date: April 4, 2001) discloses a light-weight non-burning brick of garbage fly ash, which uses 30-35 parts by weight of domestic waste incineration clinker combined with fly ash and slag Or sand and gravel aggregate, cement and other raw materials, although the technical solution disclosed in this patent can solve the problem of processing part of waste incineration slag (ie domestic waste incineration clinker), in order to meet the use requirements of the final burn-free brick product (such as strength and bulk density requirements), it still needs to be combined with a relatively large amount of fly ash, and the amount of waste incineration slag used cannot be too high (only limited to below 35% in this patent), which cannot cope with the increasing situation of waste incineration slag

[0005] China's No. 02114714.0 patent application (publication date: July 30, 2003) discloses a concrete product that utilizes 50-68wt% waste incineration ash in combination with 20-35wt% cement and other raw materials. The technical solution disclosed in this patent application uses more waste incineration slag, but also requires a large amount of cement, and is not suitable for processing a large amount of waste incineration slag at a lower cost; and , Concrete products need to be cured in a steam room at 85-90°C after forming
