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.

Aug 13, 2012 · These admixtures are sometimes added to repair mortars, but are not typically used in ready-mixed concrete. It is the hydrophilic crystalline admixtures that provide concrete with the greatest resistance to infiltration of water under hydrostatic pressure.
High Range Water Reducing Admixture for Concrete
High range water reducing admixture (ASTM C494 types F and G) decreases the water-cement ratio and provides high-performance, particularly at early ages. High range water reducing admixture reduces the quantity of mixing water required to produce concrete of a given consistency by 12 % or greater, as per ASTM C 494- C 494M.
Chemical Admixtures - Portland Cement Association
Water-reducing admixtures usually reduce the required water content for a concrete mixture by about 5 to 10 percent. Consequently, concrete containing a water-reducing admixture needs less water to reach a required slump than untreated concrete. The treated concrete can have a lower water-cement ratio.

The Benefits of Water Reducers in Concrete
Mar 26, 2018 · The water reducer doesn’t evaporate; it helps increase the slump or flow without adding water. It also allows you to maintain the desired strength that you need in the concrete. This admixture will reduce the amount of water used while increasing or maintaining the compressive strength of the concrete mix. This occurs because you are not adding water to increase slump and therefore your water cement ratio is kept at a lower level.
