The Orissa State Cooperative Milk Producers Federation Limited Tender

Providing, supplying and laying Vacuum Dewatered Flooring (VDF) of Tying Line Dori (Threads) as per the slope requirements. Laying Guide Rails to every 4 meters using MS Channels or as required in straight lines along the Line Dori, taking levels as per the slope and fixing them using concrete also called grouting and left to set for a minimum of 24 hours. Pouring the concrete in between the channels and spreading using Shovel or Hoe (Kudal/Parah). Vibrating the concrete with a poker vibrator especially to the sides of the panels. Surface Vibration the concrete using Double Beam Screed Vibrator running over the guide rails twice to achieve maximum compaction for RCC with double mats. Final levelling of the concrete using the Straight Edge/Bull Float/Aluminium Bottom (Fanti/Baddha).A system of lower mats & top mat is laid on the green concrete & this is attached to a vacuum pump. This draws out surplus water if any. (We strongly oppose dewatering of RMCs. RMCs have water cement ratio already maintained to its minimum possible level by addition of admixtures. Further dewatering decreases the water cement ratio below the required level thereby causing undulations in the surface, loss in strength and formation of cracks.). The concrete is left to stiffen. When the base concrete has stiffened to the point when foot traffic leaves an imprint of about 3-6 mm and any bleed water should now have evaporated, but the concrete should have a wet sheen, Floor Hardener is applied at an even application rate of 3-7 Kg/Sqm or as per the requirement of the floor. Application of Power Floater on the surface until the surface is sufficiently compacted & levelled with no major lines appearing any more. Final finishing using Power Trowel and trowelling until the required finish is achieved. Finish could be any of the Smooth Finish, Sand Finish or Line Finish.
