Crushing scrap tires as an aggregate to be mixed into concrete for the production of elastic concrete is an environmentally friendly way to use scrap rubber in large quantities. There have been a large number of research results on the effect of waste rubber aggregate on concrete properties. In this paper, different particle size rubber aggregate is used to prepare mortar samples with less than 25% admixture, test the rubber mortar weight, fluidity, flexural strength, compressive strength and stress-strain with rubber admixture change rule, and investigate the effect of different particle size rubber on mortar workability and mechanical properties. Under the condition of the same particle size, with the increase of rubber aggregate doping, the mortar gas content increases, the weight capacity decreases, and the fluidity decreases; under the condition of the same doping, with the decrease of rubber aggregate particle size, the mortar gas content increases, the weight capacity decreases, and the fluidity decreases. Under the condition of the same particle size, with the increase of rubber aggregate doping, the mortar gas content increases, the capacity decreases, and the fluidity decreases; under the condition of the same doping, with the decrease of rubber aggregate particle size, the mortar gas content increases, the capacity decreases, and the fluidity decreases. Under the condition of the same particle size, with the increase of rubber aggregate doping, the mortar gas content increases, the capacity decreases, and the fluidity decreases; under the condition of the same doping, with the decrease of rubber aggregate particle size, the mortar capacity decreases, and the fluidity decreases. Under the condition of the same particle size, with the increase of the rubber aggregate dosage, the mortar capacity decreases and the fluidity decreases; under the condition of the same dosage, with the decrease of the rubber aggregate particle size, the mortar capacity decreases and the fluidity decreases.
