Widely Application of Recycled Cement

摘要： Instead of being disposed of, this material can be recycled and reused. There are multiple advantages to recycling over disposal. First is the avoidance of landfill tipping fees. The national average for landfill disposal costs is approximately $30 per ton. While some C&D landfills have lower ti 阅读全文

Recycling Uses of the Cement Debris

摘要： Cement debris has a typical density of about 2,400 pounds per cubic yard, about 60% of the cement’s in-place density. Since the weight of the actual cement mass has not physically changed, the reduced density is the result of air voids (which weigh nothing) taking up approximately 40% of the rubble 阅读全文

Impact Crushers Applied in Crushing Cement

摘要： Production rates for these crusher machines are impressive, with some of the larger mobile crushers able to handle over 600 tons per hour. At an in-place density of approximately 145 pounds per cubic foot, this is equivalent to almost 8,300 cubic feet—or 550 feet of a two-lane road having a 6-inch-t 阅读全文

Detailed Steps to Break Up the In-place Cement

摘要： Breaking and EnteringBreaking up the in-place cement is the first step to excavating and removing it. This task is usually performed by hydraulic hammer attachments on standard earthmoving equipment, as well as by the smaller, manually operated jackhammers. Both machines direct their applied cyclica 阅读全文

Excellent Methods to Break Up Absolutely Two

摘要： This steel is necessary since, though very strong when subject to compressive forces—cement is weak under tension loads (it is only one-tenth as strong in tension as it is in compression). Cement by itself tends to crack under loads or as the result of contraction and expansion caused by temperature 阅读全文

Excellent Methods to Break Up Absolutely One

摘要： When planning for the excavation and removal of old, in-place cement, two questions have to be asked. First, how much cement is there? Second, what kind of cement has to be removed?Mass excavation and trenching operations typically deal with natural soil and rock. These can present their own difficu 阅读全文
