Freeze-thaw resistant concrete and preparation method thereof
The invention discloses freeze-thaw-resistant concrete and a preparation method thereof, and belongs to the technical field of water conservancy projects. The concrete disclosed by the invention is prepared from the following raw materials in parts by weight: 230 to 320 parts of cement, 1300 to 1400 parts of coarse aggregate, 530 to 580 parts of fine aggregate, 55 to 85 parts of fly ash, 125 to 130 parts of water, 0.003 to 0.005 part of air entraining agent, 0.06 to 0.08 part of water reducing agent and 2 to 5 parts of high elastic modulus fiber, the high elastic modulus fiber is obtained by reacting bagasse with polyvinyl alcohol and a silane coupling agent under a heating condition. The concrete provided by the invention has good crack resistance, freezing resistance and impermeability.
本发明公开了一种耐冻融混凝土及其制备方法，属于水利工程技术领域。本发明的混凝土，按重量份计，其原料包括水泥230‑320份，粗骨料1300‑1400份，细骨料530‑580份，粉煤灰55‑85份，水125‑130份，引气剂0.003‑0.005份，减水剂0.06‑0.08份和高弹性模量纤维2‑5份；所述高弹性模量纤维是由蔗渣与聚乙烯醇、硅烷偶联剂在加热条件下反应得到。本发明的混凝土具有很好的抗裂性、抗冻性和抗渗性。
