How to increase characteristic strength of recycled aggregate concrete

Using appropriate concrete mix design criteria, adequate concrete strengths should be achieved, even for "poor" course aggregate. The only caveat would be if poor quality fine aggregate should be used, in which case relatively more cementetious materials would be required per unit weight of the concrete, and also.
