Formula and preparation process of anti-seismic high-strength anti-crack concrete
The invention discloses an anti-seismic high-strength anti-crack concrete formula and a preparation process, and belongs to the technical field of anti-seismic concretes.The anti-seismic high-strength anti-crack concrete formula comprises the steps that S1, steel slag in filler particles is modified; s2, taking the filler particles according to the formula amount; s3, filling particle mixed materials; s4, the stones are washed after being sieved; and S5, mixing and preparing. According to the invention, the anti-shearing force capability of the concrete is enhanced and modified by the polyacrylonitrile filler fibers, and the polyacrylonitrile filler fibers have good dispersibility in cement, and have good chemical stability while resisting acid, alkali, hydrolysis and cracks, and the graphene particles can realize the modification of the temperature resistance capability. High dispersity and mixing capacity can be achieved through atomized and sprayed graphene particles and nano SiO2, the uniform scattering capacity after mixing is improved, meanwhile, the cross-linking capacity to cement and filler fibers is achieved through the micropore structure of the graphene particles and the nano SiO2, and the overall anti-seismic and anti-cracking capacity is improved.
本发明公开了一种抗震型高强度抗裂混凝土配方及制备工艺，属于抗震混凝土技术领域，S1、对填料颗粒中钢渣进行改性处理；S2、取配方量填料颗粒；S3、填充颗粒混料；S4、将石子过筛后进行冲洗；S5、混料制备。本发明中，通过对聚丙烯腈填料纤维实现对混凝土的抗剪切力能力增强改性，且在水泥中的分散性好，同时耐酸、耐碱、耐水解和抗裂缝的同时对化学稳定性好，同时石墨烯颗粒能够实现对耐温能力的改性，通过雾化喷出的石墨烯颗粒和纳米SiO2能够实现高分散性和混合能力，提高混合后的均匀分撒能力，同时通过自身微孔结构实现对水泥和填料纤维的交联能力，提高对整体抗震抗裂能力。
