CHARACTERISTICS OF PROCESSED CONCRETE RUBBLE
The results of material tests on a large number of samples from different stationary recycling plants show that the processed concrete rubble is a relatively pure material. The particle size distribution mostly meets the requirements of the aggregate grading curves. The bulk density ranges from 1,86 g/cm 3 to 2,33 g/cm 3.Limestone is a rock composed of calcium carbonate (CaCO 3 ). It is the rock type most commonly used to make crushed stone in the United States. It holds this position because it is widely available and suitable for a greater diversity of uses than any other type of rock. Limestone can be used to make cement.Crushed Stone: The Unsung Mineral Hero Geology

The History of Concrete InterNACHI®
For hydration to take place, concrete must have a minimum water-to-cement ratio of 25 parts of water to 100 parts of cement. Water in excess of this ratio is surplus water and helps make the concrete more workable for placing and finishing operations. As concrete dries and hardens, surplus water will evaporate, leaving the To crush rubble (broken cement blocks and concrete), first set the top of the Fixed Jaw to the maximum opening (150mm) and the bottom of the Fixed Jaw also to the maximum size.
