Abstract：
The influence of fly ash content on the autoclave-treated expansibility and pore parameters of concrete mixed with MgO are tested. The results show that the autoclave-treated expansibility of concrete with fly ash is reduced, but the range of reducing is reduced when the fly ash content passes 30 percent. The average in size of aperture is refined, and the proportion of innocuous and less harmful pore is increased, meanwhile, the pore structure is improved of concrete with fly ash. The more obvious inhibitory effect to the autoclave-treated expansibility and the more obvious improvement to the average in size of aperture with MgO content increasing.
