 — NEW DELHI: India's Hindalco Industries Ltd on Thursday signed an agreement with UltraTech Cement Ltd to supply 1.2 million tonnes of bauxite residue every year to be used as a raw material for cement, as part of its push for alternative methods of disposing of the toxic waste. Hindalco, India's top aluminium and copper producer, said …

4. Resulting cement quality. Its extensive use in the cement industry also means that the effects of Petcoke on the cement, the plant, and the environment, are well known. 5. Physical state and properties of the fuel. Its stable physical and chemical properties mean that the storage and handling of Petcoke is safe. 6. Economic viability.

 — Mumbai: Hindalco Industries Ltd., a global leader in Aluminium and Copper, has entered into a Memorandum of Understanding (MoU) with UltraTech Cement Ltd., India's largest manufacturer of cement and concrete, to deliver 1.2 million metric tonnes of red mud (also known as bauxite residue) annually to UltraTech's 14 plants located …

 — Laterite is a common rock found along the Western Ghats of Peninsular India. Laterites have developed mainly over Deccan Trap basalts in Maharashtra, gneisses and metasediments in Goa and parts of Karnataka, whereas it has developed on granulite-khondalite rocks in the southern state of Kerala. The laterite has been extensively …

 — Portland cement is the primary material in the field of construction. Despite its importance, its production remains an energy-consuming and polluting operation. Research on alternatives to Portland cement has become an international concern, and these alternatives include geopolymers. With the evolution of the research on …

 — West Kalimantan has very large bauxite resources, reaching 2.07 billion tons, equivalent to 57.32% of the total bauxite resources in Indonesia with bauxite reserves of 0.84 billion tons or equivalent to 66.77% of the total national mineral reserves. The researched area covers Sompak District and surrounding areas, Landak Regency, West …

manufacturing temperature and lesser CO 2 emission, accord-ing to Pu et al. (Pu et al. 2021), geopolymer concrete is regarded as one of the future green building materials as an alternative to Portland cement-based concrete. Geopolymers can categorize into acidic and alkaline geo-polymers synthesized by acid activation and alkaline activa-
