Extrusion panels and blocks utilizing bottom ash fly ash and polymer modifiers

Abstract

The present invention relates to an extrusion-molded panel and a block utilizing bottom ash, fly ash, and a polymer modifier, wherein: an extrusion-molded panel and block for building materials are manufactured by mixing, as main composition components, bottom ash and fly ash, which are coal ash, with a small amount of cement, natural pulp, polypropylene synthetic fibers, a thickener, and a polymer modifier, at a predetermined composition ratio, so that a minimal amount of cement is used in mixing, and therefore, the manufacturing cost can be reduced; the amount of carbon dioxide exhaust generated during cement production can be reduced by an amount corresponding to the reduction in the amount of cement, thereby reducing the emission of greenhouse gas; and, especially, the resource recycling range of the bottom ash, which has been recycled at low rates and discarded as environmental waste, can be extended.

Description

technical field [0001] The present invention relates to an extruded panel and block using furnace bottom ash, fly ash and a polymer modifier, in particular to a method of using coal ash, that is, furnace bottom ash and fly ash as the main composition and Add a small amount of cement, natural pulp, polypropylene synthetic fiber, thickener and polymer modifier to it according to a specific combination ratio to make extruded boards and blocks for building materials, so that it can pass as much as possible It is possible to reduce the amount of cement mixed to save manufacturing costs, and at the same time reduce the carbon dioxide emissions generated when producing cement corresponding to the saved cement amount and further reduce greenhouse gas emissions, especially to expand long-term recycling. Bottom ash, which has a low utilization ratio and needs to be discarded as environmental waste, is used for the resource reuse range of extrusion molding boards and blocks using bottom ...

Problems solved by technology

However, in addition to the above proposals, there are few other production and manufacturing methods of extruded panels for building materials using furnace bottom ash, and are used to produce and manufacture water-permeable concrete compositions such as breakwater structures or water-permeable concrete compositions. There are very limited public plans for civil engineering materials such as permanent concrete blocks, and there is an urgent need to expand the furnace bottom by disclosing more plans for the use of furnace bottom ash as civil engineering materials and extruded boards for building materials.
