TERMINOLOGY TREMIX; Special concrete floor surface harden by

admixtures and dewatering used in industrial facilities

DEWATERING ; Dewatering is the removal of water from

solid material by wet classification and filtration or similar solid liquid separation

OBJECTIVES Achieving lower water cement ratio Increase compressive strength Elimination of curling Improve wear resistance Improve water resistance

PROCEDURE Preparation of sub base Divide flooring area into panels Preparation of frame work using steel

channels

Mix design of concrete Placing of concrete and compacting Levelling and compaction by double beam

screed vibrator

Dewatering process

1. The filter pads are placed and proper sealing ensured

2. The top cover is unrolled over the filter pads

3. The top cover is connected to the suction hose of the vacuum pump and water is removed

Vacuum dewatering process

Vacuum dewatering working

Floating operation Trowelling operationFloating & Troweling take place right after

dewateringThis makes the cement more compact and

enabling to generate a very smooth finish.

Floater machine Trowelling operation curing  curing is a main process in concreting. But compare to other

concrete in this tremix concrete curing is less

STAGES OF TREMIX VACUUM SYSTEM

Suction mat

ADVANTAGES Reduced maintenance cost Earlier utilization of floors Lower water permeability Minimized crack formation Minimum dusting

Performance analysis The final strength achieved by ordinary concrete on

28 day will be achieved by tremix concrete by initial day itself.

On further curing the vacuum concrete achieves compressive strength far more than ordinary concrete.

All layers of the concrete get same strength

Compressive strength using vacuum system

APPLICATIONS Industrial flooring Railway platforms Godown , warehouses Canals Airport Runways

CONCLUSION High initial slump can be used, during

concrete pouring . Better workability than normal concrete. Lowering water cement ratio leads

increase wear resistance, compressive strength and minimum water permeability.

vacuum treatment reduce water content 15-25%

Continuous cracking is generally reduced
