Crushing Plants

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.

Crushing Plants

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.

Continuous prestressed concrete girder bridges, volume 2

The parametric design study indicated that for bridges spanning from 150–300 ft, continuous precast, prestressed concrete girder bridges with in-span splices can provide an economical alternative to steel girder bridges and segmental concrete box girder construction. The tested splice connections performed well under service level loads.

Why Prestressed? - National Precast Concrete Association

The idea of prestressing concrete was first applied by Eugene Freyssinet, a French structural and civil engineer, in 1928 as a method for overcoming concrete’s natural weakness in tension. Prestressed concrete can now be used to produce beams, floors or bridges with a longer span than is practical with ordinary reinforced concrete.

Concrete Creep Analysis Method Based on a Long-Term

Concrete creep plays a significant role in the long-term performance of the prestressed concrete structure. However, most of the existing prediction models cannot accurately reflect the in-site concrete creep in a bridge construction environment. To improve the prediction accuracy of creep effects in concrete structures, an innovative creep …

Prestressed Concrete Bridge - an overview

Six beams in the western span of this three-span prestressed concrete bridge were constructed with optical fibers cast into the concrete in the precasting factory (see Figures 29.4 through 29.6), allowing distributed strain measurements to be taken along the lengths of the prestressed beams. Fiber optic cables enter at one end of the beam and ...

Environmental Review Toolkit

Prestressed-concrete I-beams feature high tensile wires or cables embedded in the bottom flange of the beams that are stretched (stressed, or tensioned) prior to casting and curing of the concrete. The concrete and steel are in direct contact and once the concrete cures, the tension of the steel is released and the load transfers to the concrete.
