EVALUATING THERMAL PROPERTIES OF GEOPOLYMER

Jan 20, 2021In this paper, thermal properties of geopolymer from the mixture of red mud, rice husk ash, and diatomaceous earth were investigated. Red mud is an industrial waste from bauxite plants which has a negative impact to the environment if not properly managed, especially for countries mining this bauxite ore. On the other hand, rice husk ash is an agricultural waste abundant in Asian countries

Microstructural Properties of Natural Allophane

Abstract: Microstructural properties of white bauxite from Montenegro were investigated. XRD analysis showed the presence of allophane (Al2O 32SiO 23H 2O) and gibbsite (γ-Al(OH) 3). The allophane phase showed very broadened diffraction lines, thus indicating poor crystallinity as well as very fine nanoparticles in this phase.

Aluminum processing - Aluminum processing - Ores: Aluminum is the third most abundant element on Earth's surface. Only oxygen and silicon are more common. Earth's crust to a depth of 16 km (10 miles) contains 8 percent aluminum. Aluminum has a strong tendency to combine with other common elements and so rarely occurs in nature in the metallic form.
