“…Due to the high demand of concrete, replacing a small portion of the aggregates by rubber chips from waste tires, can be advantageous with two-sided merit of natural resources survival and waste management. Reuse of tire rubber to partially replace the mineral aggregates in concrete has been investigated by numerous studies in the past two decades assessing the properties of rubberized self-compacting concrete, 5 mechanical properties and hyperelastic modeling, 6 static/ dynamic modulus, 7 rubber panels and pavement, 8,9 and impact loading. 10 Despite the advantages that can be achieved due to rubber replacement, nevertheless, it can have a detrimental effect on some of the fresh and mechanical properties of the concrete.…”

Rubberized concrete containing waste tire rubber, silica fume, and zeolite cured in different curing conditions has been investigated in this paper. For this purpose, coarse aggregates were partially replaced by different percentages of waste rubber chips, namely 10% and 15%, and silica fume and zeolite were incorporated into the binder to replace 10% of cement mass. Different mixes were made and cured in two different conditions, namely in water and air with relative humidity of 100% and 50%, respectively. Compressive strengths of mixes were measured at different ages as 3, 7, 28, and 42 days. In order to simulate and predict the compressive strength of the rubberized cement composite, the influencing parameters were considered as cement content, silica fume, zeolite, rubber percentage, relative humidity, and age of the samples. Then, adaptive neuro-fuzzy inference system was employed to develop a prediction model for compressive strength of the concrete. Six variables were introduced into the adaptive neuro-fuzzy inference system model as inputs and the compressive strength was considered as the output. Prediction results and performance criteria were determined for various datasets including training, validation, testing, and all data. Parametric study of the adaptive neuro-fuzzy inference system models was also conducted to investigate the effect of each variable on the compressive strength of the rubberized concrete. Based on the correlations and errors obtained from the model, it was found that the proposed adaptive neuro-fuzzy inference system model can be a robust tool for predicting the behavior of complex composite materials such as rubberized concrete.
