Coarse aggregate reactive powder concrete for producing prefabricated bridge deck slab and preparation method of coarse aggregate reactive powder concrete
The invention relates to the technical field of concrete, in particular to coarse aggregate reactive powder concrete for prefabricated bridge deck slab production and a preparation method thereof.Cement clinker components obtained after copper tailings, gold tailings, alumina tailings and iron tailings are calcined serve as a base material of the concrete, the environment-friendly effect of waste utilization can be achieved, and the effect of recycling the waste is achieved; the performance of the prepared concrete cement can be enhanced; the modified fiber component is added into the concrete, and when the silane coupling agent modified fiber concrete is impacted, due to bridging and toughening effects of fibers, the impact resistance and toughness of the concrete can be remarkably improved; the nano titanium dioxide can be combined with silicon carbide, so that the concrete has higher elastic modulus and lower shrinkage stress, the performance of the concrete is improved, and the concrete is more suitable for production of prefabricated bridge decks.
本发明涉及混凝土技术领域，具体涉及一种预制桥面板生产用粗骨料活性粉末混凝土及其制备方法，本发明将以铜尾矿、黄金尾矿、铝土尾矿和铁尾矿煅烧后的水泥熟料组分作为混凝土的基料，既能够起到废物利用的环保作用，又能够加强制备的混凝土水泥的性能；本发明将改性纤维组分加入至混凝土中，硅烷偶联剂改性的纤维混凝土在受到冲击时，由于纤维的桥接和增韧作用，能够显著提高混凝土的抗冲击性和韧性，而且纳米二氧化钛可以和碳化硅结合使混凝土具有更高的弹性模量和更低的收缩应力，从而改善混凝土的性能，使其更适用于预制桥面板生产中。
