APPLICATION OF VIBRATIONS IN CONCRETES

A RESEARCH WORK IS REPORTED AT THE CONCRETE LABORATORY, TECHNOLOGY DIVISION OF THE GUANABARA STATE HIGHWAY DEPARTMENT IN RIO DE JANEIRO. THE OBJECT OF RESEARCH WAS TO COMPLEMENT THE WORK "ELASTIC CHARACTERISTICS OF CONCRETES BY DYNAMIC METHODS" PRESENTED TO THE FIRST SYMPOSIUM OF HIGHWAY RESEARCH, HELD IN RIO DE JANEIRO, JULY 1965. THE THEMES WERE: (1) TECHOLOGICAL CONTROL OF CONCRETES QUALITY, BY MODULUS OF ELASTICITY. (2) ESTABLISHMENT OF AN EXPERIMENTAL FORMULA RELATING THE CONCRETES DYNAMIC MODULUS OF ELASTICITY AT 7 DAYS OF AGE TO THE COMPRESSIVE STRENGTH OF CONCRETES AT 28 DAYS OF AGE, AND (3) JUDGEMENT OF THE COMPRESSIVE STRENGTH OF BROKEN CONCRETE SLABS BY RESONANT FREQUENCY./RRI/
