Abstract

Corresponding to the conventional anti-freezing agent, namely, sodium nitrite, the early strength development of the cement-fly ash composite cementitious material curing in the solution of water and sodium nitrite were investigated, respectively. The results show that, adding sodium nitrite increases the volume of sulphoaluminate in the composite cementitious material at the early stage, which lowers the strength of the composite cementitious material that curing at 5ºC. The addition of fly ash could contribute to the improvement of the later strength of the composite cementitious material that curing at 5ºC.
