2015-12-1  The test method is based on transducers measurements that consist in the monitoring, throughout a concrete column measuring 700 mm in height as a function of time, of ultrasonic velocity differences. The variations in ultrasonic velocities are used to derive indices that reflect stability of concrete and interpret the material homogeneity.

Abstract. AbstractTo evaluate the filling capacity of self-compacting concrete SCC without segregation, a technique based on the ultrasonic velocity has been adapted in order to estimate homogeneity and quality of concrete at very young age.To monitor local change in ultrasonic velocity, the process consists of using a pair of transducers at different depths of the concrete.

Prediction of the compressive strength of high

Introduction. Construction of large-span and super high-rise concrete structures has become a current trend [], posing an increasingly stringent requirement for the compressive strength of concrete.For this reason, self-compacting concrete (SCC) with high strength, self-compacting ability, and excellent load-bearing performance has been gradually used in civil engineering.

This study concerns the prediction of lateral pressure exerted by self-compacting concrete (SCC) on formwork during the casting process. This estimation is obtained using Janssen's model as used in the statics of ensiled granular material. The model has been adapted to SCC. The friction coefficient between the concrete and the wall occurring in the model is measured with a new type of tribometer.
