Influence of Partial Replacement of Fine Natural Aggregate by Fine Recycled Aggregate on Properties of Fine-Aggregate Concrete
Original language description
This paper deals influence of partial replacement of natural sand by fine recycled aggregate (FRA) on properties of fine-aggregate concrete. The recycled concrete from construction and demolition (C&D) waste were crushed from fraction 32/64 mm to fraction 0/16 mm and sieved to fraction 0/4 mm. There were prepared four concrete mixtures. One mixture was reference with natural sand. In concrete mixtures FRA10, FRA20 and FRA30, natural sand was replaced 10 %, 20 % and 30 % FRA. All mixtures were designed with the same w/c ratio, the same amount of cement and the same concrete class. There were tested mechanical and deformation properties of hardened concrete. It is possible to say that the use of the FRA in concrete influences the properties of concrete.However, FRA concrete is possible to be used in the manufacturing of building structures.
