# Floors in factories and industries have concrete being the
most versatile of flooring material, has been in use for a
long time. To overcome the deficiencies of concrete a system
was devised to improve the properties of such concrete
floors. This system is "Vacuum Dewatered Floors.
Process:
In this system, concrete is poured in place & vibrated with
a poker vibrator. Then a screed vibrator is run over the
surface, supported on channel shuttering spaced 4.0 meters
apart. The screed vibrator is run twice to achieve optimum
compaction & leveling. After this a system of lower mats &
top mat is laid on the green concrete & this is attached to
a vacuum pump. This draws out excess water.
Benefits:
1. Compressive strength of floor increases by upto 60%
2. Tensile strength increases by @ 70%
3. Cement consumption is reduced to the extent of 40%, no
cement is required separately for finishing the surface.
4. Abrasion resistance of the floor increases by @ 60%
resulting in less wear and rear of the floor surface.
5. Shrinkage of concrete is reduced and floor wraps less.
