The actual shear rate of fresh concrete during pump and spray processes should be further determined to better match the rotating velocity of rheological measurement. Moreover, … WebThese anchors are used with a hanger bar, also known as a tension bar, where the concrete is too weak for a cone anchor. They are ideal for thin panels and other applications where the concrete shear cone developed by the anchor is insufficient to provide the working load limit of the anchor e.g. low strength concrete.
