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:
Web openings produce discontinuity in the normal flow of stresses which reduces the beam shear capacity and stiffness [13][14][15][16][17]. Minimum amounts of transverse reinforcement are ...

Blasting cost. Blasting and materials handling are two core operations in aggregate quarrying industries that account for a higher percentage of operating costs when compared to other processes (Mirabedi et al. 2016). Drilling and blasting account for about 28% of the total aggregate quarrying cost (Bhatawdekar et al. 2019).
