Cautious
- After the pouring construction covers the surface using theplastic sheeting and the grass curtain, do not let it to freezeimmediately or blow the winds excessively caused the crack.Entering the mold temperature control above 5 âÂÂÂÂ??ÂÂÂÂ??degree.
- Required heating curing at the early strength fast-enhancement.After the concrete formed, if the surface iced up, this phenomenondoes not cause any the freezing damage. Theintensity will remain enhancing rapidly, when the ambienttemperature increasing.
