The experiment studies how the freeze-thaw cycles influence concrete compressive strength and elasticity modulus with different water-cement ratio under air-entraining agent zero of that value respectively. It can be found specimen reduced significantly when there is agent; durability resistance, however, makes great improvement; as cement increases, both them improves effectively. Through comparison elastic agent, optimal were determined. results used in engineering design severe cold area.
