摘要
为提升水利工程混凝土材料的抗拉性能,利用聚乙烯醇(PVA)纤维对混凝土实施改性处理,制备出采用各种不同配比方案的PVA改性混凝土,并通过万能试验机对PVA改性混凝土试件进行力学性能测试。经实验研究发现,制备出的水利工程混凝土复合材料具有较为理想的抗拉性能,该性能优势可在一定程度上改善结构构件的延性与耐久性能。
In order to improve the tensile performance of concrete materials in hydraulic engineering,we used poly(vinyl alcohol)(PVA)fibers to modify the concrete,prepared PVA modified concrete with various proportioning schemes,and tested the mechanical properties of PVA modified concrete specimens using a specialized universal testing machine in the laboratory.Through experimental research,we found that the prepared hydraulic engineering concrete composite material has satisfactory tensile properties,which can improve both ductility and durability of structural components to a certain extent.
