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.
