Mineral admixture, preparation method of mineral admixture and concrete
The invention relates to the technical field of concrete admixtures, in particular to a mineral admixture, a preparation method of the mineral admixture and concrete. The mineral admixture provided by the embodiment of the invention is used for being added into concrete to improve the performance of the concrete, and the mineral admixture is slurry composed of silica fume, lithium slag, a dispersing agent and water; wherein the admixture comprises 240 to 400 parts of silica fume, 50 to 200 parts of lithium slag, 550 to 600 parts of water and 2 to 8 parts of dispersing agent; wherein the solid content of the mineral additive is 35%-60%. The problem that the performance improvement effect on concrete is poor due to the fact that lithium slag and silica fume are used as additives for dry doping in the prior art is solved.
本发明涉及混凝土外加剂技术领域，特别涉及一种矿物外加剂、矿物外加剂的制备方法及混凝土。本发明实施例提供的一种矿物外加剂，用于添加至混凝土中改良其性能，矿物外加剂为由硅灰、锂渣、分散剂和水组成的浆料；其中外加剂中硅灰的组分为240～400、锂渣的组分为50～200、水的组分为550～600、分散剂的组分为2～8；其中矿物添加剂的含固量为35％～60％。解决现有锂渣和硅灰作为外加剂干掺对混凝土的性能改善效果差的问题。
