Environmental sustainability of recycled cement based materials (fine recycled concrete aggregates in rendering mortar)

Every year a lot of construction and demolition works are done in the entire world, especially in developed countries like European and North American countries. This caused to produce a big amount of Construction and Demolition Wastes (CDW) in the cities. In fact in the last decade a big movement started to recycle and reuse these wastes again in Construction industries. One of the most efficient ways to reuse this big amount of resources is to crash the CDW and reuse them in the concrete. There have been a lot of works done to add the Recycled aggregates from CDW to the cement based materials especially concrete. The point with ordinary concrete which there have been a lot of works done for it is the ordinary concrete have structural responsibility. But for mortar there is not this responsibility that strong. In fact it is easier to make ready mixed mortar, add anything to it and sell it in the market since its quality in acceptable. The point with mortar since it is known as less noble material than ordinary concrete it have been less concentration to work on its properties. There have been a lot of works done on the mortar recycled aggregate’s mechanical properties. Due to this introduction, I am proposing the methodology to introduce a new martial as Recycled aggregates rendering mortar. The aim and methodology are based on the logics to find new ways to improve use of recycled material in production of new materials for the building. And evaluate Environmental Efficiency of the Recycled aggregates mortar, based on durability and Environmental Impact of the Recycled aggregates mortar made with different percentages of recycled to natural aggregates mortar.
