1. INDUSTRIAL FLOORING BY TREMIX VACUUM SYSTEM GUIDED BY, Asst prof:NEERAJA.P.G Submitted By, HEBIN J CHIRIYANKANDATH

2. 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

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

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

5. Mix design of concrete Placing of concrete and compacting Levelling and compaction by double beam screed vibrator

6. 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

7. Vacuum dewatering process Vacuum dewatering working

8. Floating operation Trowelling operation Floating & Troweling take place right after dewatering This makes the cement more compact and enabling to generate a very smooth finish.

9. W Floater machine Trowelling operation curing   curing is a main process in concreting. But compare to other concrete in this tremix concrete curing is less

10. STAGES OF TREMIX VACUUM SYSTEM Suction mat

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

12. 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

13. APPLICATIONS Industrial flooring Railway platforms Godown , warehouses Canals Airport Runways

14. 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
