Nowadays, researches on the usability of recycled aggregate (RA) in concrete is gaining popularity in all over the World due to the preservation of the environment and sustainable development. RA can be obtained after crushing and screening of the construction rubble obtained from demolished structures. The recycled concrete aggregate (RCA) used to replace the natural coarse aggregates (NCA) in different proportions. Use of recycled aggregate in concrete can be useful for environmental protection. The application of recycled aggregate has been started in a large number of construction projects of many European, American, Russian and Asian countries. Mineral additives used in this experimental work are silica fume (SF) and some admixtures at various ratios. Recycled aggregate was made by crushing the waste concrete of laboratory test cubes and precast concrete columns. Concrete made entirely with natural aggregate (NAC) as a control concrete Regardless of the replacement ratio, recycled aggregate concrete (RAC) had a satisfactory performance. However, for this to be fulfilled, it is necessary to use quality recycled concrete coarse aggregate and to follow the specific rules for design and production of this new concrete type.
