| Abstract: | The influence of bentonite on the performances of the pre-placed aggregate concrete is studied based on the special structure of bentonite.With bentonite,the strength of pre-placed aggregate concrete can be increased by about 14%,the loss of strength after 50 times freeze-thaw circle can be decreased by 10%,and the construction property of the pre-placed aggregate concrete is improved. |

| Keywords: | concrete pre-placed aggregate bentonite fluidity |
