The ordinary plain concrete and high strength plain concrete were set as control samples. Decreasing water to binder ratio (W/B) was used to elevate the demolding strength of steam-cured concrete containing phosphorus slag under the same curing condition. The compressive strength and chloride ion penetration of steam-cured concrete containing phosphorus slag with decreased W/B were also investigated. The results show that addition of phosphorus slag decreases the demolding strength of the

The demolding strength of concrete containing phosphorus slag with decreased W/B is close to or even higher than that of control sample. What's more, the compressive strength development and chloride ion penetration resistance of the concrete containing phosphorus slag are higher than those of the control samples at late ages.
