Thus, the addition of silica fume increases the density of rubberized concrete, leading to the increased brittleness and reduced plasticity of the concrete. When the rubber content was 0%, the tension-compression ratios of the concrete mixes with silica fume contents of 0%, 5%, and 10% were 0.079, 0.069, and 0.063, respectively.
