Pcc Grinding Waste Characterization

major component of Portland Cement Concrete. Slurry pH neutralization tests were performed by blending compost (from two different commercial sources) with PCC grinding slurry at three slurry:compost ratios and monitoring pH as a function of time. The pH of the soil in the non-impacted area on SR-195 was in the range 6.3-7.5
