| Abstract | The prediction of fly ash concrete strength by three methods including ultrasonic pulse velocity method, electrical resistivity method and combined methods of nondestructive testing is summarized in this paper. The combination of two different instrument ultrasonic pulse velocity tests and electrical resistivity measurement were used in the study. The predicted strength by ultrasonic pulse velocity test, electrical resistivity measurement and compressive strength of fly ash concrete can be related to develop an equation to predict the compressive strength at that time with less percentage of error. The equation to estimate the prediction is based on the correlation of actual compressive strength and predicted compressive strength of fly ash concrete with 20% replacement by weight of cement with reasonable accuracy of ±15% percentage of error, the percentage of ±17% errors for normal concrete and the percentage of ±26% errors for high strength concrete. The method can be easily applied to concrete specimens as well as existing concrete structures. |
