Concrete workability time-varying test method and system based on tank strain

The invention provides a concrete workability time-varying test method and system based on tank strain, and belongs to the technical field of engineering equipment. The method comprises the following steps: establishing a correlation algorithm of fresh concrete workability and tank wall stress strain data; fresh concrete is loaded into a tank body of the concrete tank truck, the tank body is kept rotating, and stress-strain data of the tank wall are continuously collected; calculating the workability of the fresh concrete according to the correlation algorithm and the stress-strain data of the tank wall; the workability of the fresh concrete is displayed, and the concrete workability time-varying test based on the tank strain is completed. The problem that the concrete performance and quality cannot be monitored in real time in the concrete transportation process is solved. 本发明提供了一种基于罐体应变的混凝土工作性时变测试方法及系统，工程设备技术领域，该方法包括：建立新拌混凝土工作性与罐壁应力应变数据的相关性算法；将新拌混凝土装入混凝土罐车罐体中，保持罐体旋转，并持续采集罐壁的应力应变数据；根据所述相关性算法以及罐壁的应力应变数据，计算新拌混
