Concrete may take longer to crush than rock because it is not very hard when compared to many natural rocks. Oddly enough he says that the harder stuff breaks faster because the crushing energy is not "absorbed" by the material. Check it out on the web.
Method: A spring release mechanism is used to activate a hammer which impacts a plunger to drive into the surface of the concrete. The rebound distance from the hammer to the surface of the concrete is given a value from 10 to 100. This measurement is then correlated to the concretes' strength.
Mobile impact crushers are used to recycle concrete and asphalt and process natural rock. They are easy to move on and between job-sites, which allows operators to crush on smaller job-sites. Best of all they …
Concrete crushing after yielding of steel reinforcement represents an under-reinforced member, which is typical of current reinforced concrete design standards. This failure mode ensures that a high level of member ductility is maintained prior to failure, thus providing ample warning before collapse.
A new concrete crushing facility is proposed to be built in Core City, less than 100 feet from the house where Joanne Arnold's family has lived for several decades. The project, she said, "just doesn't fit" with the need for more housing in the area, or a new center being created nearby for people experiencing homeless.
