Filling material capable of absorbing carbon dioxide and preparation method thereof
The invention relates to a filling material capable of absorbing carbon dioxide and a preparation method thereof. The technical problem that an existing cemented filling body does not have the carbon dioxide absorption capacity is mainly solved. According to the technical scheme, the filling material capable of absorbing carbon dioxide is composed of fly ash, cement and basalt, and the mass ratio of the cement to the fly ash to the basalt is 1: (2-4): (8-20). The preparation method comprises the following steps: (1) firstly, selecting basalt with high contents of calcium oxide, magnesium oxide and ferrous oxide and the content of other elements close to the content of elements contained in the coal gangue; 2) testing the carbon dioxide absorption capacity of the selected basalt; 3) preparing materials in different proportions; 4) preparing cemented filling bodies with different proportions and capable of absorbing carbon dioxide, and curing; and 5) carrying out a mechanical strength test on the cured cemented filling body, and if the test result meets the mechanical strength required by engineering, determining that the ratio of the cemented filling body is the ratio of the prepared filling material.
本发明涉及一种能吸收二氧化碳的充填材料及其制备方法。主要是解决现有胶结充填体存在的不具备二氧化碳吸收能力的技术问题。本发明的技术方案是：一种能吸收二氧化碳的充填材料，它由粉煤灰、水泥和玄武岩组成，所述水泥：粉煤灰：玄武岩的质量比为1：2‑4：8‑20。其制备方法的步骤为：1)首先选择氧化钙、氧化镁和氧化亚铁含量高，且其余元素含量与煤矸石所含元素含量相近的玄武岩；2)对选择的玄武岩进行二氧化碳吸收能力的测试；3)配制不同比例的物料；4)制成能吸收二氧化碳的不同比例的胶结充填体并养护；5)对养护后的胶结充填体进行力学强度测试，若测试结果符合工程所要求力学强度，则确定该胶结充填体的配比为制备充填材料的配比。
