Anti-abrasion admixture for concrete and preparation method of anti-abrasion admixture
The invention discloses an abrasion-resistant admixture for concrete and a preparation method of the abrasion-resistant admixture, and belongs to the technical field of building materials. The admixture comprises the following components in percentage by mass: 75%-85% of ultrafine fly ash, 1%-3% of nanoscale particles and 12%-24% of modified rubber, the modified rubber is obtained by penetrating basalt fibers into pores of porous rubber, dispersing the basalt fibers on the surfaces of the porous rubber and then coupling silicon nitride particles. The superfine fly ash and the nanoscale particles are used for improving the compactness of a concrete matrix and improving the performance of an interface transition zone, the modified rubber is used for exerting the energy absorption effect and improving the strength and the crack resistance of the concrete, and under the interaction of all the components, the admixture can not only guarantee the abrasion resistance of the concrete, but also improve the strength and the crack resistance of the concrete. And the cracking of the abrasion-resistant concrete can be effectively inhibited.
本发明公开一种混凝土用抗冲磨掺合料及其制备方法，属于建筑材料技术领域。所述掺合料包括以下质量百分比的各组分：超细化粉煤灰75％～85％、纳米级颗粒1％～3％、改性橡胶12％～24％；所述改性橡胶是通过在多孔橡胶的孔内穿插和表面分散玄武岩纤维，再偶联氮化硅颗粒后得到的。本发明利用超细化粉煤灰和纳米级颗粒改善混凝土基体密实性，改善界面过渡区性能，利用改性橡胶在发挥吸能效果的同时提升混凝土的强度和抗裂性能，在各组分的相互作用下，本发明的掺合料不仅能保证混凝土抗冲磨性能，还能有效抑制抗冲磨混凝土的开裂。
