High-fracture-resistance biomass ash modified superfine powder dry hard pavement concrete and preparation method thereof
The invention relates to the technical field of cement materials, and particularly discloses high-fracture-resistance biomass ash modified superfine powder dry and hard pavement concrete and a preparation method thereof. The preparation method of the concrete comprises the following steps: a1, carrying out secondary calcination on the biomass ash; a2, preparing a mixture of modified biomass ash and latex powder; a3, preparing a water reducing agent diluted solution; a4, all the materials are mixed and stirred to be uniform. According to the invention, the biomass ash is modified by doping the superfine composite mineral admixture and the latex powder, so that on one hand, the problem of high water demand of the biomass ash concrete is improved by utilizing the micro-grading effect of the superfine composite mineral admixture; on the other hand, the pozzolanic effect of the superfine composite mineral admixture and the synergistic effect of the latex powder and the biomass ash are utilized, and the problems that after the biomass ash is doped, due to fibrous particles of the biomass ash, the concrete is loose in structure and poor in durability are solved.
本发明涉及水泥材料技术领域，具体公开了一种高抗折生物质灰改性超细粉干硬性道面混凝土及制备方法。所述混凝土的制备方法包括：a1.对生物质灰进行二次煅烧；a2.制备改性后的生物质灰及乳胶粉混合物；a3.制备减水剂稀释溶液；a4.将各物料混合并拌和均匀。本发明通过掺加超细复合矿物掺和料以及通过乳胶粉对生物质灰进行改性，一方面利用超细复合矿物掺和料的微级配效应，改善生物质灰混凝土需水量大的问题；另一方面利用超细复合矿物掺和料的火山灰效应以及乳胶粉和生物质灰的协同作用，改善生物质灰掺入后由于其自身的纤维状颗粒导致的混凝土结构疏松、耐久性差的问题。
