Use of ceramic wastes as aggregates in concrete production ...

Tabak et al. investigated the use of tile aggregate as the substitution of natural aggregate and found greater water absorption in concrete containing 100% coarse and fine tile aggregates (3.553%) than that of reference concrete (1.552%). However, they reported lower water absorption in 100% coarse tile aggregate concrete (1.394%) compared to ...

Use of recycled mixed aggregates in floor blocks ...

2017-11-20  The results show that these type of aggregates produce better results than those coming from demolitions waste. In fact, for substitution percentages below 35%, the decrease of mechanical strength is very small and, for a 100% of substitution, although there is a loss of resistance, the floor blocks satisfy the requirements of European standards.

Aggregates - Portland Cement Association

Crushed aggregate is produced by crushing quarry rock, boulders, cobbles, or large-size gravel. Recycled concrete is a viable source of aggregate and has been satisfactorily used in granular subbases, soil-cement, and in new concrete. After harvesting, aggregate is processed: crushed, screened, and washed to obtain proper cleanliness and gradation.
