Problems solved by technology

[0004] There are also many reusable resources in construction waste, and we can reprocess them into building blocks for reuse; at the same time, current building blocks will be added with retarders during processing to slow down the solidification of concrete slurry Time is convenient for operation, but the retarding effect of the current retarder needs to be improved

Abstract

The invention discloses a construction waste building block for a filling wall and a production process thereof. The construction waste building block is prepared from the following raw materials in parts by weight: 20 to 50 kg/m<3> of construction waste, 10 to 15 kg/m<3> of cement, 5 to 10 kg/m<3> of lime powder, 5 to 12 kg/m<3> of col slag, 3 to 9 kg/m<3> of gravel, 10 to 20g/m<3> of foaming agents, 15 to 25g/m<3> of glycine 2 retarders, 20 to 30g/m<3> of water reducing agents and 100 to 300g/m<3> of tackifiers. The construction waste is prepared from concrete waste materials, waste mortar,waste metal, brick and tile fragments, muck and waste asbestos boards. The glycine 2 retarders used in the process can retard the slurry solidification time; the sufficient time is provided for the slurry shaping; the phenomenon of slurry solidification before the slurry is used up cannot occur; the shaped building block is subjected to sufficient reaction, so that the intensity and the toughnessof the building block can be improved.

Description

technical field [0001] The invention relates to the technical field of building blocks, in particular to a construction waste block for filling walls and a production process thereof. Background technique [0002] Construction waste refers to the dregs, spoils, waste materials, silt and other wastes generated during the construction, laying or demolition, and repair of various buildings, structures, and pipe networks by construction units or individuals. Classified by source, construction waste can be divided into engineering dregs, decoration waste, demolition waste, engineering mud, etc.; classified by composition, construction waste can be divided into muck, concrete blocks, crushed stones, brick fragments, Waste mortar, mud, asphalt block, waste plastic, waste metal, waste bamboo and wood, etc. [0003] With the acceleration of industrialization and urbanization, the construction industry is also developing rapidly, and the accompanying construction waste is increasing....
