Recycled fiber reinforced composite material toughened concrete and preparation method and application thereof
The invention discloses recycled fiber reinforced composite material toughened concrete and a preparation method and application thereof. The recycled fiber reinforced composite material toughened concrete is prepared from the following components in parts by weight: 500-600 parts of cement, 1000-1200 parts of coarse aggregate, 500-650 parts of sand, 5-30 parts of a strip-shaped recycled fiber reinforced composite material, 0-3 parts of a water reducing agent and 200-250 parts of water. The strip-shaped recycled fiber reinforced composite material is a strip-shaped material formed by mechanically cutting the fiber reinforced composite material after the service life is reached. By adopting the strip-shaped recycled fiber reinforced composite material, the agglomeration phenomenon of the fiber reinforced composite material in the concrete can be effectively avoided, and the strength of the fiber reinforced composite material can be effectively utilized, so that the recycled fiber reinforced composite material toughened concrete has better bending resistance, ductility and impact resistance; wide application prospects are realized in engineering of anti-seismic structures, anti-collision structures and the like.
本发明公开了一种回收纤维增强复合材料增韧混凝土及制备方法与应用。所述回收纤维增强复合材料增韧混凝土，按重量份计，由包括以下组分制备而成：水泥500‑600份，粗骨料1000‑1200份，砂500‑650份，条状回收纤维增强复合材料5‑30份，减水剂0‑3份，水200‑250份；所述条状回收纤维增强复合材料为达到使用寿命后的纤维增强复合材料经过机械切割成型的条状材料。本发明采用条状回收纤维增强复合材料，能有效避免纤维增强复合材料在混凝土中出现团聚现象，也能有效利用纤维增强复合材料的强度，实现所述回收纤维增强复合材料增韧混凝土具有较好的抗弯性能、延性和抗冲击性能，在抗震结构和防撞结构等工程中有着广泛的应用前景。
