Abstract: The mortas can be considered as a mixture of the binders and aggregates with water, having capacity of the induration and adherence. Instead, it is suggested the production of mortas using civil construction waste, with plenty silicoaluminates, obtained in demolitions and reforms of build, and fly ash as material pozzolana, obtained of the combustion of mineral coal in fluidized bed boilers, in partial replacement of Portland cement. The civil construction wastes were benefited and characterized by X-ray spectrometry and X-ray diffraction. The fly ash was characterized by granulometric analyze and X-ray spectrometry. The mortars of the were prepared using the following compositions of RCC, 95, 90, 85, 80, 75 and 70%; CV of 0, 5, 10, 15, 20 and 25% e 5% of Portland CP II Z 32 cement. In all the compositions were put 0,8% of water and the rheological testing was used the same proportions residue (RCC e CV) with 35% water. The specimens were cured for 28 days and after were submitted physical trials of absorption, porosity and bulk density; mechanical trials of resistance to compression and analysis of X-ray diffraction and scanning electron microscopy. The results obtained show that the recycling of civil construction waste and the use of fly ash and RCC is a promising technique in production of mortas.
