Key Features observed
• With high slump, LC3 concrete remains flow-able in nature without using any viscosity modifying agent. • LC3 can be used for making self-compacted concrete.
Photographs
PRODUCTION OF BUILDING MATERIALS
• Paver blocks of various sizes and hollow concrete blocks were produced using industrially produced LC3 replacing Ordinary Portland Cement
• A fully automatic manufacturing unit was used to produce these products • No difficulty was observed during the entire process.
