This presentation doesn't provide enough data to conclude. I can show you terrible concrete structures, pavement, footing, pier, slab, all around in West. If this is the delivery of the project having current standards then what will happen after relaxing these standards? This presentation doesn't explain many aspects e.g. 1. How slump was increased over the time (Hydration Stabilizer!)? I don't want to guess anything. The data must talk and prove the results. 2. There is no comparison and/or test results available for 28 days Flexural Test? I don't have time to wait until 56 days to determine accepted or not. 3. No mention about actual temperature and wind! How collecting a sample at the batching plants correlates to the actual field condition? This must be discussed. 4. Permeability test results are not satisfactory but shy to mention fact and discuss. Lastly, discussing standards to make new and/or updating is different than the enforcing the standards and project specifications. Field Inspector doesn't have to know the 90-minute rule in detail, they only need to know over 90 minutes, rejected. period. no argument. No mention about durability!
