Fiber-containing composite filler material and concrete member
The invention relates to the technical field of concrete members, and provides a fiber-containing composite filler material and a concrete member, the fiber-containing composite filler material comprises a mixture of a filler material and a cementing material, and the weight ratio of the filler material to the cementing material is (0.84-25.7): (55-83.1); and the filler material comprises tailings and fibers. According to the concrete member, tailings obtained in the mining process serve as the raw material, the fibers are cooperatively added for compounding use, by adding the fibers, the crack refining effect of the fibers of the concrete member with the tailings as aggregate is improved, generation and development of early-stage plastic shrinkage cracks of the concrete member can be effectively delayed, the microstructure in the concrete member is improved, development of primary microcracks in the concrete member is reduced, the crack width of the concrete member is reduced, and then efficient disposal and cyclic utilization of tailings are promoted.
本申请涉及混凝土构件技术领域，提供了一种含纤维复合填充体材料、混凝土构件，其材料的重量比重如下：包括填充体材料和胶凝材料的混合物，且填充体材料与胶凝材料的重量比为0.84～25.7:55～83.1；填充体材料包括尾砂和纤维。本申请的混凝土构件以采矿过程中得到尾砂的作为原料，并且协同加入纤维进行复配使用，通过添加纤维，改善了以尾砂作为骨料的混凝土构件的纤维有细化裂缝的作用，能有效延缓混凝土构件早期塑性收缩裂缝的产生和发展，混凝土构件内部的细观结构得到改善，减少混凝土构件内部原生微裂纹的开展，使混凝土构件裂缝宽度减小，进而促进了对尾砂的高效处置和循环利用。
