Lanwa Sanstha Portland Composite Cement
Better Strength. Better Durability.
LANWA Sanstha Portland Composite Cement (PCC) is manufactured using clinker, slag, fly ash, and calcium carbonate, delivering better strength and durability with higher resistance to chloride attacks and carbonation. LANWA PCC creates impermeable concrete structures with improved water bleeding properties that reduce shrinkage cracking. Its chloride resistivity makes it ideal for coastal constructions. LANWA PCC has a reduced carbon footprint compared to other cement types, making it an eco-friendly high-strength construction material.
Key Features
- Better Concrete Performance — fine particles increase workability and reduce uncontrolled bleeding. Slag/fly ash reaction makes concrete denser with higher strength.
- Better Precast Products — engineered for higher strength in shorter time, supporting early-age concrete strength for precast applications.
- Improved Crack Resistance — engineered minerals increase resistance to cracking. Slag reduces bleeding and protects against desiccation cracking.
- Smooth Finishes — finely ground CaCO3 reduces friction among ingredients and delivers superior workability during finishing works.
- Coastal Construction Suitable — high chloride resistivity protects steel reinforcement in aggressive coastal environments.
- Eco-Friendly — reduced carbon footprint compared to OPC due to lower clinker percentage.
