Abstract:Mix-design of self-consolidating concrete (SCC) with construction and demolition concrete waste (C&DW) as recycled aggregates is investigated. The novelty of this paper consists in the possibility of using both fine and coarse high-grade C&DW for the preparation of new SCC. The effects of recycled aggregates on porosity measurements and mechanical investigations combined with time-dependent properties are investigated. A reference SCC mix, with natural aggregates and the same water/powder ratio as SCC with recycled aggregates, is reported for comparison. Results are correlated in an integrated approach to study the feasibility of structural SCC with medium-high mechanical strength.
Finally, this work attempts to strengthen the concept of sustainability in civil constructions.
