Wet-process carbonized magnesium slag fiber reinforced material as well as preparation method and application thereof
The invention discloses a wet-process carbonized magnesium slag fiber reinforced material and a preparation method and application thereof.The preparation method comprises the steps that magnesium slag is ground and then sieved, and magnesium slag powder is obtained; the method comprises the following steps: uniformly mixing and stirring magnesium slag powder and a MgCl2 aqueous solution to form mixed slurry, introducing CO2-containing gas while stirring, and fully stirring to obtain slurry A; and carrying out vacuum filtration treatment on the slurry A, separating out filter residues, drying, and finally grinding to obtain the product. According to the method, the industrial solid waste magnesium slag can be comprehensively utilized, CO2 in the atmosphere is effectively utilized, and the aragonite type calcium carbonate prepared through wet carbonization has the appearance of fiber characters and is high in content. The magnesium carbide slag fiber reinforced material prepared by the invention can be added into a cement-based material as a good admixture, and the toughness of the cement-based material is enhanced on the premise of ensuring high compressive strength.
本发明公开了一种湿法碳化镁渣纤维增强材料及其制备方法与应用，将镁渣研磨后过筛，得到镁渣粉末；镁渣粉末与MgCl2水溶液混合搅拌均匀形成混合浆体，搅拌的同时通入含有CO2的气体，充分搅拌后得到浆料A；将浆料A进行真空抽滤处理，分离出滤渣并烘干，最后经研磨即得。本发明能够对工业固废镁渣的综合利用，并有效利用大气中的CO2，通过湿法碳化制得文石型碳酸钙具有纤维性状的外貌，且含量高。本发明制备的碳化镁渣纤维增强材料能够作为良好的掺合料加入到水泥基材料中，在保证较高抗压强度的前提下增强了水泥基材料的韧性。
