Fracture surface of normal strength concrete under various loading rates
Original language description
The aim of this paper is to compare the fracture areas of normal strength concrete that were subjected to various loading rates. The main objective of this paper is a presentation of measured data, which can be used to determine the speed of the applied loadings using reverse engineering. The main hypothesis is that under quasi-static loading the cracks have time to propagate along the path of least energy consumption ie, around aggregate particles and through the weakest zones of the matrix while under impact loading the crack are forced to develop along straight paths throughout the stronger matrix zones and some aggregate particles leading to the higher measured strengths and lower superficial area.
