| Abstract: | The effect of activating agent on mechanical properties and long-term properties of steam-cured fly ash concrete is studied by experiments in this paper.The results show that the addition of activating agent into steam-cured concrete blended 40% fly ash is effective in improvement of its compressive strength at demolding,as well as the elastic modulus,flexural strength,tensile-splitting strength,and also permeability and shrinkage of steam-cured fly ash concrete can be improved by the activating agent. |
