Aging-resistant colored pervious concrete and preparation method thereof
The invention provides aging-resistant colored pervious concrete and a preparation method thereof. The colored pervious concrete is prepared by uniformly mixing Portland cement, steel slag, coarse aggregate, cellulose ether, a water reducing agent, an air entraining agent and an aerogel coated dye, wherein the aerogel coated dye is prepared by compounding cellulose modified beta-cyclodextrin hydrogel with silicon dioxide and then coating an oil-soluble organic dye with the formed mixture. The colored pervious concrete provided by the invention has the advantages of bright color, lasting colorfixation performance and the like, and is wide in application prospect. The silicon dioxide is compounded with the beta-cyclodextrin aerogel for coating of the dye, and the beta-cyclodextrin aerogel is of an externally hydrophilic and internally hydrophobic structure, so adsorption of the organic dye is facilitated; the beta-cyclodextrin aerogel having been compounded with the silicon dioxide hashigh tensile strength, so structural stability of the beta-cyclodextrin aerogel is facilitated; and after coating, the dye is not prone to aging in the sun, and meanwhile, the dye has high oil resistance.
本发明提出一种耐老化的彩色透水混凝土及其制备方法，所述彩色透水混凝土是将硅酸盐水泥、钢渣、粗骨料、纤维素醚、减水剂、引气剂、气凝胶包覆染料混合均匀而制得，所述气凝胶包覆染料是将纤维素改性β‑环糊精水凝胶复合二氧化硅，然后包覆油溶性有机染料而制得。本发明提供的彩色透水混凝土，具有色彩鲜艳、固色持久等优势，应用前景广阔，本发明将二氧化硅复合β‑环糊精气凝胶包覆染料，β‑环糊精气凝胶为外亲水内疏水结构，有利于对有机染料的吸附；经过二氧化硅复合后β‑环糊精气凝胶具有较强的抗张强度，有利于β‑环糊精气凝胶的结构稳定，包覆后使得染料在阳光下不易老化，同时具有较强的耐油性。
