Abstract:Uniaxial compression test is carried out using WAW-E2000 hydraulic servo universal testing machine under the four different air entraining agent content of concrete samples. We analyzed the compressive strength of concrete samples, elastic modulus variation, limit compression strain and damage property. The results showed that: With the incorporation of air entraining agent content increases, the compressive strength of concrete, elastic modulus and ultimate compressive strain decreased gradually, while the extent of the initial damage increases.
