Phase 3: Pilot / Production Scale Feasibility for LC3
- Selection of one kaolinitic clay in consultation with the cement company depending on its quality and availability
- Lab-scale testing of clays to re- confirm the quality of raw materials.
- Calcination tests in a furnace to define optimum calcination temperature.
- Calcination of clay in rotary kiln and determining calcination parameters
- Grinding in a continuous ball mill to establish grinding parameters, including use of grinding aids.
- Preparation of LC3
- Evaluation of LC3 in mortars
- Evaluation of LC3 in two grades of concrete (M25 and M50)
- Selected durability tests in two concrete grades i.e porosity, chloride ingress, carbonation and sulphate resistance
- Performance report of LC3 using selected clay.
- Durability test reports on selected grades of concrete
- Recommendations on use of admixtures and grinding aids.
- Life cycle assessment of LC3 production compared to standard production.
- Note: If more durability parameters need to be tested, it can be done for additional charges.
- Required raw materials to be sent to TARC New Delhi for performing tests. Exact quantity will depend upon the testing required.
