The purpose of this paper is to develop a framework for managing wastes resulting from the tire rubber valorization waste of quarry sand mortar. A research methodology was developed to achieve the above-mentioned main objective. To create a framework for use of crumb rubber in the production of quarry sand mortars, with adequate physical and mechanical properties to be used in a variety of construction applications. Testing included strength and thermal conductivity properties of the various mixture composition subjected to varying by 5%. 10%. 15% and 20% by quarry sand substitution. The internal microstructure, and phase composition of all mixture mortars, were investigated using scanning electron microscopy and energy-dispersive X-ray spectroscopy (SEM/EDS). The results show that increasing incorporation rate of additives significantly improves thermophysical properties of based materials, the hardened properties of the various mortars made are analyzed and compared, the experimental results revealed that; the addition of crumb rubber waste in the quarry sand mortar is beneficial for physical properties (Mv) mass loss, The results of mechanics strength of the rubber based quarry mortar studied are also significantly reduced.The addition of 5% to 20% rubber crumb in matrix and the replacement of sand by 20% of rubber in quarry mortar record the low thermal conductivity properties including that appropriate QS and CR levels may change the pattern of quarry sand mortar. witch explain by a Larger pore and higher porosity produce a less rigid and uniform matrix, meaning that the sonic pulses must travel through longer and more miscellaneous paths which improvement of insulation. The good performance of new materials encourages us to integrate them into the building envelope.
