Concrete prepared from tailing sand and preparation method thereof
The invention relates to the technical field of concrete, and particularly discloses concrete prepared from tailing sand and a preparation method of the concrete. The concrete prepared from the tailing sand comprises the following components in parts by mass: 150-155 parts of water; 265 to 270 parts of cement; 40 to 45 parts of fly ash; 750 to 800 parts of tailing sand; 1050 to 1100 parts of broken stone; 27 to 33 parts of composite whisker; 4-6 parts of an additive; the composite crystal whiskers are compounded from calcium titanate crystal whiskers, silicon nitride crystal whiskers and magnesium borate crystal whiskers. The method has the advantage of improving the strength of the concrete.
本发明涉及混凝土技术领域，具体公开了一种利用尾矿砂制备的混凝土及其制备方法。利用尾矿砂制备的混凝土包括以下质量份数的组分：水150‑155份；水泥265‑270份；粉煤灰40‑45份；尾矿砂750‑800份；碎石1050‑1100份；复合晶须27‑33份；外加剂4‑6份；复合晶须为钛酸钙晶须、氮化硅晶须、硼酸镁晶须的复配。本发明具有提高混凝土强度的优点。
