摘要：This paper consists of an overview over the development of recycling of concrete and the use ofconcrete with recycled materials. The trend of the utilization of recycled aggregates for the developing infrastructuresis the solution to the problem of an excess of waste material, not forgetting the parallel trend of improvement of finalproduct quality. The utilization of waste construction materials has to be related to the application of quality guaranteesystems in order to achieve suitable product properties. Therefore the complete understanding of the characteristic ifnew materials becomes so important in order to point out its real possibilities. The studies on the use of recycledaggregates have been going on for 50 years. In fact, none of the results showed that recycled aggregates are unsuitablefor structural use. Only having inadequate number of studies in durability aspects, made recycled aggregates to bepreferred just as stuffing material for road construction. In the present study, an experimental investigation wasconducted to study the properties of concrete, when the Natural Coarse Aggregate (NCA) is replaced with RecycledCoarse Aggregate (RCA). Specimens are prepared with natural, recycled coarse aggregates and to be tested after acuring periods of 7 and 28 days. The use of recycled aggregates in concrete opens a whole new range of possibilities inthe reuse of materials in the building industry.
