MARKFLOW EP100
DESCRIPTION COMPATIBILITY
MARKFLOW EP100 is a specially formulatedpowder additive which when mixed with cementitious system imparts shrinkage compensation and high flow ability, pump-ability to the mix. It produces controlled expansion and minimizes water demand. The plasticising agent allows the use of a reduced water cement ratio which increases strength and durability.
MARKFLOW EP100 is compatible with mosttypes of Portland cements including Rapid Hardening Portland cement. During the winter months when temperatures may fall to below 10°C, it is recommended that Rapid Hardening Portland cement should be used in grouts for filling the ducts of post-tensioned concrete members.
FEATURES / ADVANTAGES
- Based on gaseous expansion system
- Reduces water demand, improves strength and pump-ability
- Most economical to use
- Compatible with wide range of chemical and mineral admixtures and rapid hardening Portland cement and most types of Portland cement
- Chloride Free
- Pre-packed grout overcomes potentials on site variations and it increase cohesion and improves fluidity.
TYPICAL APPLICATIONS
- Cavity Filling
- Cable duct grouting
- Site batched repair
- Filling up the plumbing and electric chases
- Filling gaps between precast elements
- Repairing honeycombs by pressure grouting

DIRECTIONS FOR USE
SURFACE PREPARATION: All areas to be grouted must be clean and free of oil, grease, dirt and contaminants. Remove all loose materials. Where required, provide air- relief openings to avoid entrapment of air. All metal components to be in contact with grout must be free of rust, paint, or oils. All concrete to come in contact with the grout must be thoroughly saturated with clean water for a minimum of 12 hours before placement of grout. Remove excess water from holes and voids just before grout placement.
MIXING: First take approximately 80% of the water in the mixer and then the Portland cement, mix thoroughly until the cement has been completely dispersed. Then add MarkFlow EP100 and sand (if any is being used), and continue mixing a further 2 minutes or until complete dispersion of the MarkFlow EP100 is achieved. Add the required quantity of water from the remaining 20 % until the desired consistency is achieved. Too much dosage of EP100 will increase expansion and it may cause frothing
PLACING:
Cable Duct: Grouts for ducts of post-tensioned concrete members should be passed through a 1.18mm BS sieve before reaching the pump, and the pump should be capable of giving a continuous flow of grout to the injection equipment.
Bed grouting: Placing should be without interruptions until completion. Place the mixed grout into the pouring hopper of the formwork within 15 minutes after mixing. Place from one side only.
SPECIAL NOTE : MARKFLOW EP100 SHOULD NOT BE USED WITH HIGH ALUMINA CEMENT
