Preparation method of waste wood recycled aggregate concrete
The invention discloses a preparation method of waste wood recycled aggregate concrete, which comprises the following steps: (1) diluting glycerol with absolute ethyl alcohol to form a base solution, then adding potassium magnesium phosphate cement, tricalcium silicate powder, sodium alginate powder and fly ash into the base solution, and uniformly dispersing to form slurry; and coating the surface of the wood aggregate with the slurry, and airing to obtain the modified wood aggregate. And (2) mixing basalt fibers with alkali liquor, then carrying out heat preservation, and washing the basalt fibers after the heat preservation is completed, so as to obtain the modified basalt fibers. And uniformly mixing the modified basalt fiber and the modified wood aggregate with ordinary Portland cement, gravel, sand, fly ash, a water reducing agent and mixing water to obtain the concrete slurry. According to the technical scheme, the strength of the concrete containing the wood aggregate is effectively improved, and popularization and application of the waste wood in the concrete are facilitated.
本发明公开一种废弃木材再生骨料混凝土的制备方法，包括步骤：(1)用无水乙醇将丙三醇稀释形成基液，然后将磷酸钾镁水泥、硅酸三钙粉末、海藻酸钠粉末、粉煤灰加到所述基液中分散均匀形成浆料。然后将所述浆料包覆到木材骨料表面，晾干后即得改性木质骨料。(2)将玄武岩纤维与碱液混合后进行保温，完成后对所述玄武岩纤维进行洗涤，即得改性玄武岩纤维。然后所述改性玄武岩纤维、改性木质骨料与普通硅酸盐水泥、碎石、砂子、粉煤灰、减水剂、拌和水混合均匀，即得混凝土浆料。本发明的技术方案有效提升了含有木材骨料的混凝土的强度，有利于促进废弃木材在混凝土中的推广应用。
