Mobile crushing plants are built ready-mounted on their own travel gear. Semi-mobile plants, on the other hand, are moved from one location to the next as a piggyback load on separate haul units. Each crushing plant comes ready to operate with its own feed hopper, feed conveyor, discharge conveyor and material transfer belt. The size and design of the crusher naturally depends upon the work that it is intended for.
Semi-mobile crushing plants are always to be recommended when a change of location in long periods is required in order to optimize the raw material transportation- and operational-costs of the quarry department.

Admixtures for recycling of waste concrete
These types of admixtures, defined as extended-set control admixtures, 1 not only have a significant influence on the production, transportation, and placement of concrete, but have also had a positive impact on the environment. With this technology, in fact, it is possible to eliminate or greatly reduce the amount of waste in the production and use of concrete.
Use of Cement Hydration Stabilizer Admixture at Ready Mix
Concrete from ready mix plant is the main raw material consumed in construction industry. A significant waste quantity is generated with fresh concrete returned to the production center due to their inadequate allocation or demand preview. To minimize the amount of this material wasted, misused, discarded, could be used the Hydration Stabilizer Admixture (HSA).
Guidelines for Use of Waste Concrete Fines
new concrete production as mixing water, and experiments to date have been largely supportive of this form of recycling. Recycled wastewater used in fresh concrete production must adhere to the same guidelines for any concrete mixing water, ASTM C1602.

RECYCLING OF WASTE CONCRETE
Recycling of waste concrete is done to reuse the concrete rubble as aggregates in concrete. The recycled concrete aggregates have less crushing strength. The recycled concrete aggregates have less crushing strength, impact resistance, specific gravity and has more absorption value as compared to fresh aggregates.
