Controls cracking
Recron 3S prevents the micro shrinkage
cracks developed during hydration, mak-
ing the structure/plaster/component in-
herently stronger. Further, when the loads
imposed on concrete approach that of fail-
ure, cracks will propagate, sometimes rap-
idly. Addition of Recron 3 s to concrete and
plaster arrests cracking caused by volume
change (expansion and contraction), sim-
ply because 1 kg of Recron 3s offers mil-
lions of fibres which support mortar/con-
crete in all directions.
Reduction in water permeability
A structure free from micro cracks prevents
migration of water or moisture through-
out the concrete. This in turn helps prevent
the corrosion of steel used for primary re-
inforcement of the structure. This results
in longevity of the structure.
Reduction in rebound loss
Recron 3s fibre reduces rebound “splatter-
ing” of concrete and shotcrete. This reduces
wastage of mortar and speeds up the pace
of work. More importantly it saves a great
deal of labour employed for the job. The
gains are higher when plastering is in
progress at higher floors, ceilings and out-
side surfaces of the buildings.
