Fluid Mixture Composition Using Carbon Dioxide-Collecting By-Products

Abstract

The present invention relates to a fluid mixture composition using carbon dioxide-collecting by-products and, particularly, to a fluid mixture composition, which uses carbon dioxide-collecting by-products and is for expressing early strength, reducing the amount of solidifying agent, improving freezing and melting characteristics, improving abrasion resistance, and improving fluidity and materialseparation characteristics by adding, as an additive to the fluid mixture composition, an absorption solution having calcium carbonate (CaCO3) generated therein by using an absorption solution havingcalcium hydroxide (Ca(OH)2) and an alkaline mixing agent, which are mixed, so as to collect carbon dioxide, during the preparation of a fluid mixture composition using all types of industrial by-products, which can be used as a main aggregate of a solid product and are generated in various forms such as: in situ inferior soil, which cannot be utilized as high-quality soil and should be inevitablydiscarded; coal ash, which a is by-product of coal-fired power generation; slag, which is a by-product of the steel-making industry; a pulverized product of plain concrete; and dredged soil.

Description

technical field [0001] The present invention relates to flowable hybrid compositions utilizing carbon dioxide to capture by-products, and in particular, to utilizing hybrid calcium hydroxide (Ca(OH) 2 ) and the absorption solution of the alkaline mixture to capture carbon dioxide and generate calcium carbonate (CaCO 3 ) is mixed with the fluidity mixed composition as an additive, thereby achieving the development of early strength, reduction of cured material content, improvement of freeze-thaw properties, improvement of abrasion resistance, fluidity and utilization of material separation properties A flowable mixed composition of carbon dioxide capture by-products. Background technique [0002] Generally speaking, the burial or backfilling at the construction site mainly utilizes the soil produced on site for compaction. At this time, according to the type of work, there are quality management standards for compaction, and the detailed standards are different according to...

AI Technical Summary

Problems solved by technology

[0013] However, such calcium carbonate (CaCO 3 ) is limited in use, and currently needs to be used in many fields

[0014] In addition, in order to obtain calcium carbonate (CaCO 3 ) and use it, must go through other dehydration, drying, powdering processes, so the preparation cost increases, and the separation liquid after separating calcium carbonate is directly discarded, thus there is a problem of causing environmental pollution
