Portland Cement Concrete - an overview ScienceDirect

Like recyclate from Portland cement concrete, the quality and characteristics of recyclate from old bricks depends a lot on the strength of the bricks. High-strength (‘engineering’) bricks can produce reasonable aggregates, but softer bricks will generally produce a higher proportion of fines in the mix with less flaky coarse pieces. Lower quality bricks usually have water absorbing ...
