Applications:
– Marine concrete construction (seawalls, docks, bridges).
– High-strength concrete production.
– Dams, canals, tunnels, water tanks, and reservoirs.
– Flooring and façade work.
– Corrosion-resistant concrete.
Benefits:
✔ Increased compressive, flexural, and tensile strength.
✔ Enhanced abrasion resistance.
✔ Significantly reduced permeability.
✔ Protection against chloride, sulfate, and other destructive chemical ingress.
Dosage:
RW Microsilica can be added at 3–7% by weight of cement. (Since it improves concrete strength, it can replace an equivalent amount of cement.)
Important Note:
Microsilica reduces water content, so it must be used with a superplasticizer. Otherwise, it may cause cracking, reduced workability, and poor compaction.
Application Method:
Blend the required amount with dry mix components before adding water and superplasticizer.
