to using recycled concrete aggregate in the production of concrete mixes, the industrial implementation in the GCC countries of these technologies is still in its infancy. Therefore, there is a good potential for using recycled concrete aggregate as a subbase layer in roadway pavement construction. The company used.8 million tons of recycled aggregate in 20 of the needed concrete used in the City. The results showed that the compressive and tensile strengths values of the recycled concrete aggregate increased as the recycled aggregate and the silica fume contents increased. In addition, there have been some efforts to implement the results of research into practice. The center is capable of recycling a total of 2,300 tons of mixed domestic waste and a total of 5,000 tons of construction waste per day. The UAE seems to be one of the most active countries in the Gulf region when it comes to the application of concrete recycling. In the process of producing sustainable concrete in Qatar, efforts towards using recycled aggregate and waste concrete are underway. Also, the recycled aggregate concrete showed lower modulus of elasticity and durability characteristics.

Conservation of natural resources, saving of energy in word count dissertation production and transportation, and reduction of pollution are also the advantages of recycling. The experimental program considered ranges of pavement loads, material gradations, compositions, and layer thicknesses. Sustainable construction aspires to apply this concept to the construction industry. Although cement is produced locally, the raw materials are often imported from other countries. However, replacement of natural aggregate by recycled aggregate was found to decrease the workability of the concrete due to the high absorption characteristics of the recycled aggregate. Abdelfatah and Sami. This is accomplished by using less natural materials, consuming less energy, causing lower levels of pollution, and reducing waste while gaining the same benefits that can be achieved through the use of tradition construction methods and materials. (3)There are few studies regarding the economic feasibility and financial implications of recycling and re-use of concrete rubbles in construction applications.(4)Research on the environmental impacts of using such recycled material in construction has been rarely addressed in the region.(5)Real-life applications of using recycled construction waste. While in some countries concrete batching plants recycle the water they use for cleaning, in the Gulf it is very limited. However, sustainability requires commitment and investment by all parties involved in the construction industry, both governmental and private.
