# 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.

can we find any technical issue if we are gong to change the dimensions of steel beams from one type to another type IE if there are any equievelant data base to find solution for problem of changeing sectios of beam from one type to another with the same cross sectional area.
Why do we not deduct steel volume to find actual volume of concrete in practical as we have studied that,,, actual volume of concrete = volume of column- volume of steel pls explain with reference of IS code?????
