混凝土材料性能检测影响因素分析

Factors affecting the results of building materials testing

混凝土材料的质量,决定着工程建设的质量。对混凝土强度、钢筋保护层厚度以及结构实体位置和尺寸偏差的检验方法进行了详细介绍,对5种混凝土强度检测法的优缺点进行了分析,指出加荷速度、取样、材料、操作技能、设备的精确性、测量环境的温度和湿度等方面是混凝土材料性能检测的影响因素,提出要加强源头控制(建筑材料)和过程控制,以确保混凝土材料性能的检测质量得到保障。

The quality of the concrete material determines the quality of the project construction.In this paper,the test method of the concrete strength,the thickness of the protective layer of the steel bar and the position and the size deviation of the structural entity is introduced in detail,and the advantages and disadvantages of the five kinds of concrete strength detection methods are analyzed,and the accuracy of loading speed,sampling,material,operation skill and equipment is pointed out.The temperature and humidity of the measuring environment are the influencing factors of the performance test of concrete materials.Only from these aspects,the quality of the concrete material can be guaranteed.
