Portland Composite Cement

Portland Composite Cement

Manufactured using clinker, slag, fly ash, and calcium carbonate, Portland Composite Cement (PCC) deliver better strength and durability with higher resistance to chloride attacks and carbonation, in the concrete. LANWA PCC is successfully used for creating impermeable concrete structures. The concrete made using LANWA PCC has improved water bleeding properties, which help to reduce the shrinkage cracking of concrete. Further, the chloride resistivity of LANWA PCC will make it suitable for coastal constructions.

Due to the combination of minerals used in its manufacturing, LANWA PCC has a reduced carbon footprint compared to other types of cement. Due to the combination of minerals used in its manufacturing, LANWA PCC has a reduced carbon footprint compared to other types of cement, making it an eco-friendly construction material that delivers higher-strength concrete. The modified characteristics of LANWA PCC make it an ideal choice for producing durable concrete structures while extending its capabilities for using other applications like finishing works. Further, the developed microstructure of concrete made with LANWA PCC delivers dense concrete, while finer calcium carbonate particles in LANWA PCC facilitate the concrete flow effectively within reinforcement.

Produced through a thorough quality controlling process, including a mineral combination to deliver improved fresh concrete properties, LANWA PCC complies with the quality requirements of SLS 1697:2021 of Sri Lanka Standard Institute.

product features

Better Concrete Performance

LANWA PCC is developed by a finely ground combination of clinker, slag/fly ash, and CaCO3. Fine particles in the LANWA PCC increase concrete workability and reduce the possibility of uncontrolled bleeding in concrete. The reaction of Slag / Fly ash would make the concrete much denser while increasing its strength and providing further protection for the steel reinforcement of the concrete. Finely ground CaCO3 particles fill the small cavities in the concrete, reducing porosity and the permeability of water and other reactive chemicals.

Better Precast Products

LANWA PCC is engineered to deliver more strength in a shorter time, which supports the achievement of high strength at an early age of the concrete. Compared to conventional cement, this helps precast concrete producers in reducing the time necessary for formwork removal. Furthermore, LANWA PCC would enable the fabrication of lean precast segments at competitive prices by supporting the use of high-strength concrete mixes with lower cement contents.

Improved Crack Resistance

The engineered minerals in LANWA PCC would increase the concrete’s resistance to fresh and hardened stage cracking. Ground slag particles in the LANWA PCC would improve the bleeding rate in concrete and protect it against cracking caused due to severe desiccation. Furthermore, the slag in it will extend the period allotted for concrete surface finishing. Concrete produced with LANWA PCC will resist corrosion ion penetration and assist in preventing corrosion of the reinforcing steel. As a result, the frequency of reinforcement steel corrosion-related cracks will decrease.

Smooth Finishes

LANWA PCC is produced by introducing finely ground CaCO3 into the cement. Finely ground CaCO3 particles would reduce the friction among the ingredients in concrete and deliver superior workability during finishing works. Further, Tiny CaCO3 particles within the cement.
