回弹法作为现场检测混凝土强度的无损检测技术之一,其便捷、测试费用低、检测结果相对可靠的特点,使该方法从国外引进至今在我国得到广泛使用。本文主要如何对强度为10～60MPA泵送混凝土立方体试件进行试验,获得试件的回弹值、碳化深度值、混凝土抗压强度值,通过对试验数据分析,确定其相互关系,最终建立地区测强曲基准线,并对曲线进行验证和评价。以供交流。
As one of the non-destructive testing technologies for on-site testing of concrete strength, rebound method is characterized by its convenience, low test cost and relatively reliable test results. Therefore, this method has been widely used in our country since it was introduced from abroad. In this paper, how to test the strength of 10 ~ 60MPA pumped concrete cube specimens to obtain the rebound value of the specimen, depth of carbonation, concrete compressive strength values, through the analysis of test data to determine the relationship between the final establishment of the region Strength test curve baseline, and to verify and evaluate the curve. For exchange.
