Hi - I’m looking at the NRMCA v3.2 regional baselines. When I look at the pages for ‘Benchmark Mix Design’ I can see the average ingredients in each mix. Portland cement, fly ash, slag cement, water, etc. I don’t see a line for ground limestone as I would expect to see in a Type 1L mix. Is that elsewhere, is this report before Type 1L became standard in many places, or am I just missing something?

Thanks!

Kjell

Hi Kjell - yes, the data used in the report is from 2019, pre-pandemic, before PLC was standard practice.

Thanks,
