“…Indirect one-step sintering involves the using waste glass powder with or without other wastes that are by-products of high-temperature industrial activities or combustion processes, such as fly ash and slag, and with or without foaming agent addition. Mustaffar and Mahmud (2018) prepared glass-ceramic foams from a mixture of waste glass, fly ash, and SiC (foaming agent). Ma et al (2018) obtained glass-ceramic foam from coal fly ash and calcium carbonate (CaCO3) sintered at four varying temperatures of 1100°C, 1150°C, 1200°C, and 1250°C.…”

The development of glass-ceramic foam has received significant attention in building and construction, given its potential for sustainability. This study investigated the low-temperature route of fabricating glass-ceramic foams from mining waste. The feasibility of one-step or chemical-aided sintering of glass-ceramic foams using granite powder, a naturally sourced mining waste, rather than using already heat-treated wastes such as glass and fly ash has been explored in this study. Glass-ceramic foam samples were synthesized from a homogenous blend of constant percentage by weight of granite-clay mix with varying amounts of alkali-silicate solution. The influence of the alkali-silicate solution on the physicomechanical and microstructural properties of the synthesized samples sintered at 850°C was investigated. The results showed water absorption of 9.5-33.3%, apparent porosity of 18.2-56.7%, bulk density of 1.7-1.91 g/cm3, and compressive strength of 20.7-26.3MPa. The glass-ceramic foam developed in this research can be suitably used for the thermal insulation of buildings.

“…Several researches on fabrication of glass-ceramics foam are commonly based on the use of by-products of high tem-perature industrial activities including metallurgical slag, fly ash and waste glass among others [13][14][15][16][17][18][19][20][21][22][23][24][25][26]. However, in view of the limited resources of these pyrotechnical industrial wastes for mass production of value-added products, the raw material base route for production of glass-ceramics foam is relevant [27,28].…”

In this study, samples of glass-ceramics foam were obtained from granite dust-clay-maize cob composite and chemical additives at low temperature. Effects of the addition of maize cob as the pore-forming agent as well as the chemical additives on the performance properties of the samples of the glass-ceramics foam were investigated. The result of the prepared glass-ceramics foam showed water absorption, apparent porosity, bulk density, compressive strength and thermal conductivity of 25.6-46.7%, 43.5-75%, 1.45-1.9 g/cm 3 , 0.7-9.7 MPa and 0.11-0.53 W/m.K. respectively. The mechanical and thermo-physical properties as well as microstructural properties of the glass-ceramics foam synthesized in this study provide a feasible indicator that the material can be used in promoting green and sustainable buildings.Cite this article as: Odewole PO.
