Flexible reinforced fiber concrete and preparation method thereof
The invention discloses a flexible reinforced fiber concrete. The concrete is prepared from the following raw materials in parts by weight: 110-130 parts of ordinary Portland cement, 10-15 parts of high-iron aluminophosphate cement, 25-30 parts of modified waste rubber particles, 5-10 parts of polyolefin elastomer, 3-6 parts of flotation deinking slag fibers, 3-5 parts of modified sepiolite fibers, 10-20 parts of silicon carbide powder, 5-10 parts of bamboo fiber powder, 10-15 parts of a polycarboxylate superplasticizer, 3-5 parts of magnesium fluosilicate, 10-15 parts of slag powder, 3-7 parts of coal ash, 160-170 parts of sand, 460-480 parts of pebbles and 50-60 parts of water. The invention also discloses a preparation method of the flexible reinforced fiber concrete. The flexible reinforced fiber concrete disclosed by the invention has the characteristics of good deformability, high toughness, high strength and good adhesive property, and the expansion stress of the concrete is absorbed by utilizing the elastic characteristics of the modified waste rubber particles and the polyolefin elastomer, so that the overall volume stability of the concrete is good; and the concrete is matched with other materials, so that the overall flexibility of the concrete is remarkably improved.
本发明公开了一种柔性增强型纤维混凝土，是由以下重量份的原料制得的：普通硅酸盐水泥110‑130份、高铁磷铝酸盐水泥10‑15份、改性废橡胶颗粒25‑30份、聚烯烃弹性体5‑10份、浮选脱墨渣纤维3‑6份、改性海泡石纤维3‑5份、碳化硅粉10‑20份、竹纤维粉5‑10份、聚羧酸减水剂10‑15份、氟硅酸镁3‑5份、矿渣粉10‑15份、粉煤灰3‑7份、砂160‑170份、石子460‑480份、水50‑60份。本发明还公开了该柔性增强型纤维混凝土的制备方法。本发明的柔性增强型纤维混凝土具有变形能力好、韧性高、强度高、粘结性能好的特性，利用改性废橡胶颗粒和聚烯烃弹性体的弹性特性来吸收混凝土的膨胀应力，使混凝土整体的体积稳定性好，与其它材料之间相互配合，显著提升混凝土整体的柔性。
