• Rubber particles were dipped into NaOH solution in order to wipe the zinc stearate generated in the process of preparation of rubber power. Rubber with different particle diameters and mixing amount (sand replaced in equal volume percentage) was adopted to produce rubberized concrete specimens. A series of tests including compressive strength tests, flexural strength tests, elastic modulus tests and ultimate strain ratio tests were done respectively. The results of tests showed that the value of the compressive strength, flexural strength and elastic modulus decreased with the increase of the mixing amount of rubber, while the decrease amplitude was different from each other. The value of ultimate strain increased a little and the ability of toughness and deformation of rubberized concrete were enhanced obviously through dipping rubber particles into NaOH solution.
