Super Plasticizer LS-1R
Description: LS-1R is a retarding super plasticizer based on modified ligno-sulphonate.
LS-1R improves concrete properties such as slump, workability, mechanical strengths and durability.
LS-1R complies with ASTM C – 494 Type G.
Uses: - Mass and high temporature places concreting
- Production of free flowing concrete
- Slabs and foundation, walls, columns, piers and textured surface finishes
- Pre-cast concrete elements
- Bridges and cantilever structures

Advantages: - Improvement of workability.
- Increase placing ability in slender components with packed reinforcement.
- Decrease the time of vibration.
- Up to 10% water reduction.
- Chloride free and without any corrosion.
Dosage: Add 0.8% to 1.5% cement weight of LS-1R to cement water with further mixing of at least one min for each cubic meter of concrete. You can reduce 10% or more of the mixing water without any decrease in workability of concrete.
