Study on Workability Testing of Concrete Based on Rheological Properties
By measuring the slump and yield stress of fresh concrete and collecting data to establish a mathematical relationship model between the working performance of concrete and theology,the test results of ICAR rheometer show that the measured yield strength combined with the mathematical relationship model can be used to infer the slump of fresh concrete to characterize the working performance of concrete.The on-line testing device for concrete workability includes the processes of data acquisition-simulation calculation-data uploading-real-time monitoring,which can achieve the purpose of automated testing of concrete workability.
