    Thewaste cementcontent is mostly avoided as it tends to accumulate in the fine by-products, ∼20% by mass (Shuto et al., 2014). Studies on the use of recycled aggregates and sand in new concrete found that thewaste cementcomponent should be removed, as it increases porosity beyond accepted levels (Tam et al., 2007, Iizuka et al., 2010).
