However, at 7 days, gravel concrete exhibits slightly higher compressive strength than crushed stone concrete. It is worth noting that with similar workability and compressive strength, using well-shaped crushed stone can save approximately 20–75 kg of cement per cubic meter of concrete, significantly reducing production costs.

The mix ratios for concrete are typically expressed in terms of the proportions of cement, sand, and coarse aggregates. In the case of C20 concrete, the "C" stands for compressive strength, and "20" denotes a characteristic compressive strength of 20 megapascals (MPa) or 20 N/mm2.

However, this trend is not linear. The decrease rate of compressive strength may increase at a faster rate as the number of freeze–thaw cycles increases. The results of the compressive strength ratio show that the compressive strength of the cement-stabilized crushed stone base gradually decreases with the increase in freeze–thaw cycles.
