Additionally, this benchmark stops at 7200, while ASTM standards for precast concrete pavers is a minimum of 8000 psi and some suppliers have higher internal standards ensuring the best qualitity, particularly where products are exposed to freeze-thaw conditions. Higher values should be added as benchmarks.

The credit language should cite the source of the benchmark data for each material like CLF 2023 Baseline Report, NRMCA, or EC3.
