Generally, the more portland cement that is added to the mix, the higher the psi rating of the concrete. For example, a traditional 3000 psi mix contains 5 sacks of cement per cubic yard of concrete. To achieve 4000 psi, you'll need 6 sacks of cement (which is why higher psi mixes are often more expensive).

For example, bluestone pavers have a compressive strength of 19,000 psi, while granite pavers boast a compressive strength of 21,000 psi. In contrast, the average concrete paver has a compressive strength of 8,000-10,000 psi. So, if you need extra strength, opt for thicker pavers made of granite or bluestone.
