Mineral admixture and concrete using mineral admixture
The invention discloses a mineral admixture and concrete using the mineral admixture. The mineral admixture is prepared by mixing the following components in parts by mass: 8-10 parts of silica fume,10-20 parts of a tailing admixture, 69-81.5 parts of limestone powder and 0.5-1 part of dihydrate gypsum. The mineral admixture replaces fly ash and is added into the concrete, and the concrete usingthe mineral admixture can allow the addition amount of an additive to be increased, so the possibility that the additive is over-doped due to fluctuation of the quality of raw materials in the prior art is greatly reduced, the quality of the concrete is greatly improved, and the waste of resources is avoided; and meanwhile, the mineral admixture can also improve the water-retaining property of theconcrete, so the concrete can keep good flowability from production to construction; and the tailing admixture is selected when the mineral admixture is prepared, so the concrete is greener and moreenvironment-friendly.
本发明公开了一种矿物掺合料及应用该矿物掺合料的混凝土，该矿物掺合料由硅灰、尾矿掺合料、石灰石粉以及二水石膏混合而成，所述硅灰的质量份数为8～10份，所述尾矿掺合料的质量份数为10～20份，所述石灰石粉的质量份数为69～81.5份，所述二水石膏的质量份数为0.5～1份。该矿物掺合料替代粉煤灰加入混凝土，使用该矿物掺合料的混凝土可允许添加的外加剂掺量增加，这使原来由于原料质量波动导致外加剂超掺的可能性大大减小，混凝土的质量有了极大地提升，避免了资源的浪费；同时，该矿物掺合料还能提升混凝土的保水性，使混凝土从生产到施工都能保持良好的流动性，而且在制备该矿物掺合料时选用了尾矿掺合料，更加绿色环保。
