A detailed laboratory investigation of waste tire rubberized self-consolidating concrete (SCC) was carried out in two phases. The first phase focused on proportioning rubberized mixtures using local materials that meet European specifications for SCC in termsof  flow, passing ability, and resistance to segregation. This phase resulted in a selection of four mixtures: one control mixture (no rubber) and three rubberized mixtures containing 10, 20, and 30% waste tire rubber. The second phase of testing concentrated on analyzing the hydration process of the retained mixtures using the results of the semi-adiabatic calorimetry test as well as performing conventional mechanical tests. Results show that rubber particles do not affect concrete hydration rate, but do decrease the adiabatic temperature, given its high specific...
