Title:Determination of compressive strength of concrete using its sonic properties
Author(s):Kesler, Clyde E.; Higuchi, Yoshiro
Subject(s):Compressive Strength
Sonic Properties
Abstract:In predicting the quality of concrete by sonic methods, the prediction is usually based on the initial modulus of elasticity; however, considering concrete as viscoelastic, an anaLysis of a rheological model or concrete clearly shows that a property in addition to the initial modulus of elasticity must be co~1dered. The one property, other than modulus of elasticity, that promises to he of greatest help in predicting the strength of concrete is the coefficient of viscosity. While this property may be an excellent one to use, it cannot be determined readily from sonic tests of cone irate; but, logarithmic dee rement, which is related to the coefficient of viscosity, can be easily obtained from sonic tests. To establish whether or not there exists a relationship between the modulus of elasticity and damping capacity of con crete and the compressive strength of concrete some 300 standard 6 in. by 12 in. cylinders were tested. From the test data a set of curves are obtained from which the strength of concrete, made of aggregates used in this investigation, can be predicted. The accuracy of the prediction is generally within an error of five per cent. This accuracy can be obtained without knowledge of the age, mix, or moisture cont~nt of the concrete. The re sults clearly show why the use of the modulus of elasticity alone is not sufficient, as previously believed, to accurately predict the strength of concrete.
