Evaluation Method of Pavement Concrete Air-Entraining Agent

  title={Evaluation Method of Pavement Concrete Air-Entraining Agent},
  author={Ke Guoj},
The rationality of methods of thin cement paste shaking bubble,cement mortar divergence and real density to evaluate the concrete air entrained performance were discussed,and then it was proved by measurement of air content,bubble structure and freeze-thaw durability of hardened concrete.Results show that preliminary judgment of air entrained performance could be made through thin cement paste trial.The higher the initial bubble,the better the bleed air performance is;the faster the bubble… CONTINUE READING
