Abstract
Concrete is a large-scale building material with an important impact on environment mainly due to the production technology of cement and also because it consumes depleting mineral resources as aggregates. Therefore, it is necessary to find ways to replace some of its components in order to diminish its pollution effect. One of these is the partial replacement of cement with other cementitious materials and/or the replacement of mineral aggregates with renewable ones. The aim of this study was to investigate the effects on density, compressive strength, and split tensile strength of the concrete in the case of cement replacement by fly ash in a proportion of 10%, 20% and 30% of the volume, in the case of aggregates replacement by 20% of the volume with aggregates made of waste, and then these two cases combined. Even if the experimental results revealed the decrease of mechanical properties by replacing cement and the mineral aggregates, the smaller density of the developed concretes represents an important advantage.
