Recron 3s is a virgin polyester & polypropylene mono-filament fiber manufactured by Reliance Industries in India. It is a specially Engineered and shaped (Triangular) synthetic fiber for use in concrete and mortar to overcome various shortcomings of concrete. Specially designed triangular fibers provide higher surface bonding.
Early cracks in plasters aren’t just unpleasant but they are indicative to something wrong in material selection or the procedure used for application. The most Common defects observed in plasters are plastic shrinkage cracks & drying shrinkage cracks.
Types of Cracks in Plaster
Drying Shrinkage Cracks
Drying shrinkage result due to moisture loss after the plaster has hardened. Plaster is bound to shrink and crack. Usually , Plaster applied in layers that are too thick (i.e., >20mm) will tend to crack in this way.
Plastic Shrinkage Cracks
Plastic Shrinkage crack results when an excessive amount of water is lost from the plaster in the first few hours after its application.
With the help of Recron 3S Fiber, we can prevent above two types of cracks.
Applications of Recron 3S Fiber
- RCC & PCC like lintel, beam , column, flooring and wall Plastering.
- Foundations, Tanks Manhole Covers and Tiles.
- Roads and Pavements.
- Hollow blocks and precast items.
- Various ready mix concrete application.
- Wherever cement is used, Recron 3S can be used to improve the quality of construction.
Mix Proportions
Plaster
Use 6 mm Recron 3S @125 gm/bag of cement of 50Kg in 1:4 cement sand ratio. Dosage rate can be altered as per requirement. Content of this pouch should be used with half cubic meter (1/2 m3 ) of concrete
Concrete
Use 12 mm Recron 3S 900 gm /cubic meter.
There are more than 65-70 million fibers in one m3 of concrete which holds on the cement matrix. This arrests shrinkage stress (reduced micro cracks and permeability). Fiber matrix helps Improve energy absorption and abrasion resistance.
Direction of Use
Mixer
Sprinkle the fiber in the rotating site mixer with 2- 3 liters of water /add aggregate/sand/cement and balance water and rotate it as usual
Manual Mixer
- For best result, use one bag of recron 3s (125 gm) with one bag of cement.
- Soak half a pouch of Recron 3S in a bucket of water
- Mix half a bag of cement and required sand thoroughly an make a pond.
- Pour content of the bucket into the pond and mix thoroughly for a few minute.
Note
Recron 3S is for improving the quality of construction. It also results in saving of cement and sand helps completing target job earlier.
Advantages
- Rebound loss reduced by 40-70% .
- Result in saving of expensive mortar, cement and sand .
- Time taken for plastering is reduced and work is completed faster.
- Reduces water seepage and protects steel in concrete from corroding and walls from dampening.
- Protects corners in precast slabs and concrete flooring.
- Increases abrasion resistance by over 30% thereby increasing life of roads, walkways and floors.
- Also reduces pitting of the floor.
