Alkali-reducing enhanced apatite biomimetic mineralization method for vegetation concrete
The invention belongs to the technical field of building materials, and particularly discloses an alkali-reducing reinforced apatite biomimetic mineralization method for vegetation concrete, which comprises the following steps: S1, preparation of the vegetation concrete: mixing cement, charcoal and metakaolin, then mixing silica sol and a water reducing agent with water, then adding the mixture into the previous mixed material to form slurry, and uniformly stirring the slurry; and finally, adding aggregate, uniformly mixing, and carrying out casting molding or mold molding. S2, spraying, alkali reducing and curing are conducted on the plant-growing concrete formed through casting till cast-in-place plant-growing concrete is obtained; and carrying out marked curing on the mold-formed vegetation concrete until demolding, then carrying out carbon curing, and finally, carrying out soaking alkali-reducing curing to obtain the prefabricated vegetation concrete block. According to the method, alkaline substances and carbonate in the vegetation concrete are converted into hydroxyapatite through raw material adjustment of the vegetation concrete and treatment of the maintenance procedure, the enhancement effect is achieved while alkali is reduced, and the vegetation concrete has the advantages of being good in abrasion resistance, good in water retention, good in biocompatibility, low in manufacturing cost, environmentally friendly and the like.
本发明属于建筑材料技术领域，具体公开了一种植生混凝土的降碱增强磷灰石仿生矿化方法，S1、植生混凝土制备将水泥、生物炭和偏高岭土混合，然后将硅溶胶和减水剂用水混合后加入前面的混合物料中形成浆体，最后加入集料混匀后进行浇注成型或者模具成型；S2、对于浇注成型的植生混凝土进行喷洒降碱养护至得到现浇植生混凝土；对模具成型的植生混凝土进行标注养护至脱模，再进行碳养护，最后进行浸泡降碱养护得到预制植生混凝土块。本发明通过植生混凝土原料调整及养护工序的处理，将植生混凝土中的碱性物质及碳酸盐转化为羟基磷灰石，降碱的同时起到增强作用，且具有抗冲磨性能好、保水性好、生物相容性好、造价低和环保等优点。
