The Tensile Strength of Fresh Concrete after Simulated Earthquake at Magnitude of 6-8
This study concentrates on investigating the tensile strength of fresh concrete after the occurrence of an earthquake. The experiments have been carried out through the simulated earthquakes that were generated by a high-performance vibrating platform with a size of 6m><6m, provided by the Nuclear Power Institute of China. There are three types of ground acceleration (0.05g, 0.10g, 0.25g) acting on 10 kinds the fresh concrete (C30 and C50) with five ages (12hours,24hours,48hours,72hours,168hours) respectively. The modified El centro was used to take the recordings of the time series of parameters. The results show that the tensile strength of the fresh concrete undergoing the simulated earthquake can be well recovered after 28 days.
