Self-curing regenerated brick-concrete aggregate concrete and preparation method thereof
The invention relates to self-curing regenerated brick-concrete aggregate concrete and a preparation method thereof. The self-curing regenerated brick-concrete aggregate concrete comprises a gelling component, a fine aggregate, a coarse aggregate, a water reducing agent and water; the coarse aggregate comprises one or two of natural broken stone and tailing waste stone, and further comprises regenerated brick-mixed aggregate; and the regenerated brick-mixed coarse aggregate accounts for 10-30% of the volume of the coarse aggregate. According to the invention, natural aggregate in the concrete is partially replaced by the regenerated brick-concrete coarse aggregate, and the regenerated brick-concrete aggregate concrete with excellent self-curing and thermal insulation properties is developed by combining the characteristics of high porosity and high water absorption of the regenerated brick-concrete aggregate.
本发明涉及一种自养护再生砖混骨料混凝土及其制备方法。自养护再生砖混骨料混凝土，包括胶凝组分、细骨料、粗骨料、减水剂和水；其中，所述粗骨料包括天然碎石、尾矿废石中的一种或两种，还包括再生砖混骨料；所述再生砖混粗骨料占所述粗骨料体积的10‑30％。本发明以再生砖混粗骨料部分替代混凝土中的天然骨料，结合再生砖混骨料孔隙率高、吸水率高的特点，开发出具有自养护和保温性能优良的再生砖混骨料混凝土。
