If you lack experience estimating concrete crushing jobs, you can keep the material prep and the actual concrete crushing separate. For the material prep, you could offer an hourly rate for an excavator, operator, and pulverizer, while for the actual concrete crushing, you can offer a cost-per-ton rate. In your crushing rate, you should factor in:

— The hardness of the material is typically measured in terms of compressive strength, ie the maximum force that the material can withstand before breaking. Hardness levels can range from that of concrete at 7000 psi to 50,000 psi for ores or other hard materials. The harder the material, the longer it may take to crush.
