国内外硬化混凝土性能测试方法标准对比研究
|
摘要
混凝土作为用途最为广泛的建筑材料,其质量与建筑物结构安全关系重大,科学合理的测试方法是准确表征及评价硬化混凝土性能的基础,因此,国内外对硬化混凝土的性能测试均制定了相应的标准。本文从试件与试模、试件的制作和养护、抗压强度、试验机规范、抗折强度、劈裂抗拉强度、密度以及压力渗水深度等方面对比研究了欧洲与我国硬化混凝土性能测试方法标准之间的异同,可为我国标准的改进和修订提供借鉴。
Concrete is the most widely used building material, and its quality is very important to the structural safety of buildings. A scientific and reasonable test method is the basis for accurately characterizing and evaluating the properties of hardened concrete. Therefore, domestic and international standards for the performance testing of hardened concrete have been formulated. In favor of the continuous improvement of China's standards and provide useful data and information for standard revision work, the similarities and differences between the standard of performance testing methods for hardened concrete in Europe and China are compared from the aspects of specimen preparation, trial manufacture,specimen fabrication and maintenance, compressive strength, test machine specification, flexural strength, splitting tensile strength, density and pressure seepage depth,which can provide a reference for the development of the standard.
