No extra laboratory curing time shall be allowed for cylinders that are delivered late to the laboratory. C. Temperature-controlled storage boxes for test cylinders shall be provided, as specified in Section 8.3.2.1 of CAN/CSA A23.2-3C for a period of at least 24 hours and for protection of the cylinders from adverse weather and mishandling until removed from the Site. 1. A max-min thermometer shall be provided for each storage box and for recording site curing temperatures for all test cylinders. 2. Storage in a portable building which will be used during the first 24-hour storage period shall not be permitted. D. Test cylinders shall be tested in compression in accordance with CAN/CSA A23.2-9C by an independent CSA certified testing laboratory. E.
