This paper presents new recommendations for recycling and reuse of concrete. It shows the influencing parameters for decreasing and increasing the concrete strength under compression. These parameters are the percentage of recycled aggregates used in new compositions of concrete, the age and the state of the original concrete, the addition of cement and plasticizer, and the nature of the original aggregates. Fixing some parameters and with some additions, we could increase the recycled concrete strength and even obtain the original value of concrete strength. The paper shows a new way to get structural recycled concrete.
