Embodiment Construction

[0075] figure 1 Indicates a geopolymer comprising at least two lateral flow materials. In some cases, even more lateral flow materials can be used to form the hardenable paste. A common feature of these side stream materials and their mixtures is that they include silicon oxide SiO 2 and alumina Al 2 o 3 , silica and alumina react with each other and form a paste that hardens to a compressive state. The compressive strength achieved is at least 10Mpa, but usually exceeds 40Mpa, and sometimes even exceeds 80Mpa.

[0076] Industrial side stream materials are for example tailings such as red mud. Other side stream materials are slags from the steel industry, such as blast furnace slag, steel slag and steel refining slag. Ashes from the energy industry (such as organic ash from wood burning, and inorganic ash from coal, oil shale, etc.) are also side stream materials. Ashes may include fly ash, grate ash, or bottom ash formed in boilers. Other lateral stream materials are ...

Abstract

An arrangement and a method for mixing and handling industrial side-stream materials. A mixer (6) is arranged onto a movable work machine (5) and it is used for mixing at least two side-stream materials to form a geopolymer. The side-stream materials are processed between a waste pile (4) and a casting area (13) in the mixer (6). Cast paste is allowed to harden and after that it is crushed to obtain an earthwork material.

Description

technical field [0001] The present invention relates to an arrangement and method for mixing and processing side stream material. [0002] The objects of the invention are described in more detail in the preambles of the independent claims of the present application. Background technique [0003] Large quantities of industrial side stream materials such as ash, slag and sediment are formed in industry. Often, utilization of these commercial side stream materials is difficult due to the components contained in these materials. Additionally, it has been found to be difficult to handle these side stream materials. Therefore, the side stream materials are difficult to utilize and even have to be dumped in waste dumps. Production plants generate enormous costs and environmental risks due to waste. Contents of the invention [0004] The idea of ​​the present invention is to provide a new and improved arrangement and method for mixing and processing industrial side stream mat...
