Mix proportion design of anti-freezing and anti-permeability low-strength concrete and its corresponding mechanical properties
Abstract：Through carefully choosing the mix proportion design of low-strength concrete,the anti-freezing,anti-perme- ability and mechanical properties of concrete were studied. The effects of optimal water-to-cement ratio, mixing amount of air-entraining agent on anti-freezing and anti-permeability characteristics of concrete were researched. Furthermore, the compressive strength of concrete under condition of saturated situation and natural curing were also studied respec- tively. The researches show that by using of mixing proper amount of air-entraining agent and choosing suitable water- to-cement ratio, the anti-freezing and anti-permeability of low-strength concrete can be obviously improved without re- ducing concrete strength and anti-permeability properties in severe cold areas in China.
