Spontaneous combustion coal gangue all-light concrete brick as well as preparation method and application thereof
The invention provides a spontaneous combustion coal gangue all-light concrete brick. The spontaneous combustion coal gangue all-light concrete brick comprises the following raw materials: cement, fly ash, silica fume, spontaneous combustion coal gangue coarse aggregate, spontaneous combustion coal gangue sand fine aggregate, mixing water, a water reducing agent, an early strength agent, an air entraining agent, polypropylene mixed fiber and a functional material. The preparation method mainly comprises the following steps: pretreating the raw materials, feeding and stirring, pouring, vibrating and forming, and curing to obtain the spontaneous combustion coal gangue all-light concrete brick. The apparent density of the prepared spontaneous combustion coal gangue all-light concrete brick is 1920 kg/m < 3 >-2138 kg/m < 3 >, the strength grade is greater than or equal to C20, and the anti-freezing grade is greater than or equal to F50. The invention further provides application of the spontaneous combustion coal gangue all-light concrete brick, the spontaneous combustion coal gangue all-light concrete brick can be used for preparing the spontaneous combustion coal gangue all-light concrete Hui-style archaized brick, the problems that traditional Hui-style building materials are high in production cost, high in energy consumption, low in efficiency and capable of polluting the environment are solved, and the spontaneous combustion coal gangue all-light concrete archaized brick is high in product additional value and good in application prospect. And a new green development direction is provided for manufacturing the archaized brick.
本发明提供了一种自燃煤矸石全轻混凝土砖，原料包括水泥、粉煤灰、硅灰、自燃煤矸石粗集料、自燃煤矸砂细集料、拌合水、减水剂、早强剂、引气剂、聚丙烯混合纤维和功能材料。制备方法主要包括：原料预处理、投料搅拌、浇注振捣成型和养护，得到自燃煤矸石全轻混凝土砖。所制备的自燃煤矸石全轻混凝土砖表观密度为1920kg/m3～2138kg/m3，且强度等级≥C20，抗冻等级≥F50。本发明还提供了一种自燃煤矸石全轻混凝土砖的应用，可用于制备自燃煤矸石全轻混凝土徽派仿古砖，解决了传统徽派建材生产成本高、能耗高、效率低和污染环境的问题，自燃煤矸石全轻混凝土仿古砖，产品附加值高，也为仿古砖的制作提供了一个新的绿色发展方向。
