1 - The contractor has to start the curing as per ACI 308R and ACI 308.1 – 98 recommendations.
2 - Using curing compound is not allowed:
- As per SAIC – Q – 1028 “Curing compound shall not be used for curing of precast and prestressed concrete elements.â€
- SAES – Q – 012 Para 6.9.2 refers to SAES – Q – 01 sec. 10 which is using steam curing or water curing only.
3 - Precast defect repairs as per my comments in submittals DS – 308 and DS – 207.
