The difficulties related to non-biodegradable waste management raise the danger of environmental and health issues since millions of worn rubber tires are discarded yearly. Over the past several years, the building industry has been compelled to use this material combined with cement-based products due to the material's accessibility and vast manufacturing volume. Due to its promising properties, including enhanced ductility, damping ratio, and vibration resistance, recycling used tire rubber as a partial replacement of natural stones in concrete is a topic of intense research. Conversely, the rubber aggregator reduces the mechanical characteristics and workability of the resulting concrete mixtures. This study reviews the feasibility of using shredded rubber tire waste as a partial replacement for traditional aggregates in concrete. The properties of the rubberized concrete are discussed with respect to various ratios of rubber tire waste and traditional aggregates. The results of previous studies showed that using rubber tire waste as an aggregate in concrete significantly reduces the mechanical properties of the concrete, including its compressive strength, tensile strength, and flexural strength. On the other hand, using rubber tire waste as an aggregate reduces the weight of the concrete, which may have potential benefits for structural design. Overall, the study suggests that recycling rubber tire waste as an aggregate in concrete is a viable approach for solid waste management and can also provide environmental and economic benefits.

Background: Over the last few decades, many researchers have investigated the properties and behavior of concrete mixtures incorporating rubber-based solid wastes as a partial substitution of natural aggregates. Within this context, they have conducted experimental studies and developed numerical models that simulate the nature of rubberized concrete. Some of these mathematical simulations were intended to provide a rapid mixture of proportioning approaches and property estimation methods. Currently, it is believed that regression analysis provides an effective tool to simply construct a mathematical expression that models a set of data. For that reason, multiple linear regression was extensively utilized in predicting rubberized concrete properties in the literature. However, the performances of regularized regression analysis approaches were not evaluated even though they provide better alternatives to traditional regression methods in terms of controlling the overfitting issue. Objective: This study aims to assess the performance of Ridge, Lasso, and elastic net regression models in estimating the compressive and tensile strengths, and modulus of elasticity of rubberized concrete. Additionally, it intends to benchmark their capabilities against the traditional multiple linear regression method. Methods: Multiple linear regression, Ridge regression, Lasso regression, ElasticNet regression, Bayesian ridge regression, Stochastic gradient descent, Huber regression, and Quantile regression methods were used in the study. Result: In general, the research findings illustrated the superior performance of regression assessment in modeling the mechanical properties of rubberized concrete. Conclusion: Indeed rubberized concrete mechanical properties can be better modeled using regularized regression techniques, such as ElasticNet-based SGD compared to traditional methods, such as MLR.
