摘要
选用合成纤维可提高混凝土的断裂韧性、抗裂和抗渗性能 ,减小收缩 ,使高强混凝土结构的延性提高 ,混凝土拌和物流变性改善。实验研究了合成纤维、粉煤灰对混凝土结构的抗裂、抗渗、断裂性能、收缩及钢筋握裹力等性能的影响。
The selection of synthetic fiber may increase the fracture flexibility, cracking-proof and seepage-proof of concrete, decrease shrinkage, increase the expansibility of high strength concrete structure and improve rheological property of concrete mixture. The experiments study the influences of synthetic fiber and fly ash on cracking-proof, impermeability,fracture, shrinkage and reinforced bar gripping force of concrete structure.
