Expansive anti-crack fiber concrete and preparation method thereof
The invention relates to the field of building materials, and particularly discloses expansive anti-crack fiber concrete and a preparation method thereof. The expansive anti-crack fiber concrete is prepared from the following components in parts by weight: 280-360 parts of cement, 200-230 parts of river sand, 470-510 parts of artificial sand, 950-990 parts of gravel, 150-190 parts of water, 120-150 parts of an admixture, 43-49.5 parts of an additive, 30-50 parts of a fiber capsule and 15-25 parts of an accelerator. The fiber capsule is prepared by mixing and spray-drying the following raw materials in parts by weight: 1-2 parts of polyphenylene sulfide fiber, 0.5-0.7 part of an alpha-cyanoacrylate adhesive, 0.25-0.3 part of an epoxy resin adhesive and 2-3 parts of an o-cresol formaldehyde epoxy resin. The expansive anti-crack fiber concrete has the advantages that crack repairing can be accelerated, the repairing time is shortened, and when the concrete is damaged again, the expansive anti-crack fiber concrete still has high self-repairing performance.
本申请涉及建筑材料领域，具体公开了一种膨胀抗裂纤维混凝土及其制备方法。膨胀抗裂纤维混凝土包括以下重量份的组分：280‑360份水泥、200‑230份河砂、470‑510份人工砂、950‑990份碎石、150‑190份水、120‑150份掺合料、43‑49.5份外加剂、30‑50份纤维胶囊、15‑25份促进剂；纤维胶囊由包括以下重量份的原料经混合、喷雾干燥制成：1‑2份聚苯硫醚纤维、0.5‑0.7份α‑氰基丙烯酸酯胶粘剂、0.25‑0.3份环氧树脂胶粘剂和2‑3份邻甲酚醛环氧树脂。本申请的膨胀抗裂纤维混凝土具有能加快裂缝修复，缩短修复时间，且当混凝土再次破损时，仍具有较高的自修复性能的优点。
