In order to study the effect of shaped mortar for theme park packaging shaping stone on structural durability,two typical moulding mortar were tested under spraying or hand direct shaping to evaluate the durability of shaped mortars.The compressive strength,carbonation,freeze-thaw and chloride ion penetration were used as experimental index.The results showed that the construction process and the environmental action grade had significant effects on the durability of the mortar.Typical plastic mortars are significantly deficient in resistance to carbonation,freeze-thaw erosion and chloride ion erosion while meeting strength requirements,so special attention is highly needed to the long-term durability of plastic mortars during design and use.
