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.
