CONCRETE SUBJECTED TO HIGH RATES OF LOADING IN COMPRESSION

Synopsis Compression tests on concrete specimens have been carried out at very high rates of loading with a specially constructed drop-harnmer apparatus which enabled load-time and strain-time curves to be determined. The effects of varying the length and platen restraint of the specimen, mix proportions, maximum aggregate size, age at test and type of cement have all been investigated and compared with results for both static tests and earlier tests at high rates of loading.
