Low-alkali regenerated vegetation concrete as well as preparation method and alkali reduction method thereof
The invention discloses low-alkali regenerated vegetation concrete as well as a preparation method and an alkali reduction method thereof. The vegetation concrete is prepared from the following raw materials in parts by weight: 1421 to 1460 parts of recycled aggregate, 184 to 224 parts of cement, 40 to 56 parts of fly ash, 13 to 28 parts of silica fume, 1 to 3 parts of a water reducing agent, 1 to 1.4 parts of a retarder and 78 to 84 parts of water, the recycled aggregate is reinforced recycled aggregate obtained by soaking and modifying in a water glass solution; the fly ash is superfine fly ash. According to the invention, building solid waste or industrial solid waste is taken as a main raw material, natural aggregate is completely replaced, and meanwhile, part of cement is replaced, so that secondary utilization of solid waste resources is realized; the superfine fly ash is introduced as an admixture, the superfine fly ash is more excellent in performance than common fly ash, particles of the superfine fly ash are extremely fine, a ball effect can be generated when the superfine fly ash is applied to the concrete, the coating uniformity of the slurry on the aggregate is improved, and the micro-aggregate characteristic and the volcanic ash activity are beneficial to the development of the strength of the concrete and the reduction of the alkalinity. And double optimization of efficient ecological restoration and building performance is realized.
本发明公开了一种低碱再生植生混凝土及其制备方法、降碱方法。植生混凝土的原材料包括以下重量份的组分：再生骨料1421～1460份，水泥184～224份，粉煤灰40～56份，硅灰13～28份、减水剂1～3份、缓凝剂1～1.4份、水78～84份；再生骨料为经水玻璃溶液浸泡改性得到的强化再生骨料；粉煤灰为超细粉煤灰。本发明以建筑固废或工业固废作为主要原料，完全代替天然骨料的同时代替了一部分水泥，实现了固废资源的二次利用；引入超细粉煤灰作为掺合料，超细粉煤灰比普通粉煤灰性能更优异，其颗粒极细，应用到混凝土中会产生滚珠效应，有利于改善浆体对骨料包裹的均匀性，且微集料特性和火山灰活性有助于混凝土强度的发展和碱度降低。实现高效生态修复和建筑性能的双重优化。
