    Analysis of shear rate inside a concrete truck mixer 
    Wallevik, Jon Elvar; Wallevik, Olafur Haralds (Elsevier BV, 2017-05)
    In addition to the mixing energy applied to the fresh concrete (i.e. shearing during mixing), the shear history after mixing is also important. This applies especially to binder rich concretes like the different types of high performance concrete (HPC). ...

    Concrete mixing truck as a rheometer 
    Wallevik, Jon Elvar; Wallevik, Olafur Haralds (Elsevier BV, 2020-01)
    An increasing interest has emerged in correlating the output of the concrete mixing truck to values obtained by rotational rheometers. The output of the former has usually been the hydraulic pressure needed to turn the drum. In such research, experimental ...
