Abstract

In this study, using type CEM I 42.5 R Portland cement, limestone powder, polypropylene fibers and super plasticizer, additive foam concrete specimens were produced. 28 days compressive strengths, dry densities, ultrasonic pulse velocities and thermal conductivity coefficient of these samples were determined. Analysing test results, it was noticed that there underlies a strong relationship between ultrasonic pulse velocity and thermal conductivity coefficient in the foam concrete. It is possible to estimate thermal conductivity by ultrasonic pulse velocity method, easy and credible method.
