“…9 The common raw materials for fabrication of glass foams are waste glass, which are kind of enormous solid wastes derived from leftover in glass manufacturing process, building glass and waste glassware. [12][13][14][15][16] Specifically, a mixture of raw glass powder and a small amount of foaming agent (commonly referred to as pore-foaming agent or blowing agent) are sintered in air. 10 European Union produces about 900,000 tonnes of glass wastes every year.…”

“…11 The most widely used route for fabrication of glass foams is direct foaming using waste glass powder with foaming agent. [12][13][14][15][16] Specifically, a mixture of raw glass powder and a small amount of foaming agent (commonly referred to as pore-foaming agent or blowing agent) are sintered in air. These foaming agents generate gas by decomposition or chemical reaction at elevated temperature and meanwhile the emitted gas is wrapped by molten glass to form pores in glass matrix.…”

In this paper, a novel fabrication method for glass foams has been introduced based on colloidal suspension foaming method using waste glass as starting materials. It is demonstrated for the first time that foam stabilization via in‐situ hydrophobization of waste glass particles is possible. The fabrication conditions for stable glass particle‐stabilized foams are optimized by investigating the influences of pH value, concentration of propyl gallate and ball milling time, respectively. It is demonstrated that this is a versatile method for fabrication of stable foamed glass suspension and final glass foams with small pore size of dozens of microns, which is much smaller than that of most glass foams in previous literatures. This novel method enables both closed pore structure and open pore structure simply by tailoring solid loading of glass suspension. A “sieve‐like” hierarchical pore structure can be achieved by adjusting sintering temperature. The glass foams with controllable structure could be applied in thermal insulation fields for closed pores, and in catalyst loading, filtration, and separation fields for open pores and hierarchical pore structure.

“…Foam glass is a thermal-insulating and soundproof material with a history dating back to 1930s, when the pioneering developments were realized in France and the former Soviet Union. Later on, several studies were performed in this field in the United States, United kingdom, Germany, Czech Republic and Japan [1]. It is produced by mixing fine glass powder of 100-500 µm (nowadays, almost entirely supplied as ground recycled glass) with a foaming agent of 75-150 µm (e.g., CaSO 4 , CaCO 3 , water glass, aluminum slag, coal and SiC) and firing the mixture at 700-900 • C. At such temperatures, the glass melts while the foaming agent decomposes, resulting in the formation, Materials 2020, 13, 5458 2 of 14 upon cooling, of a rigid cellular material [2] with porosity and pore diameter of 80-90% and 0.1-5 mm, respectively [3].…”

Evaluation of Physical Properties of a Metakaolin-Based Alkali-Activated Binder Containing Waste Foam Glass

et al. 2020

Foam glass production process redounds to large quantities of waste that, if not recycled, are stockpiled in the environment. In this work, increasing amounts of waste foam glass were used to produce metakaolin-based alkali-activated composites. Phase composition and morphology were investigated by means of X-ray powder diffraction, Fourier-transform infrared spectroscopy and scanning electron microscopy. Subsequently, the physical properties of the materials (density, porosity, thermal conductivity and mechanical strength) were determined. The analysis showed that waste foam glass functioned as an aggregate, introducing irregular voids in the matrix. The obtained composites were largely porous (>45%), with a thermal conductivity coefficient similar to that of timber (<0.2 W/m∙K). Optimum compressive strength was achieved for 10% incorporation of the waste by weight in the binder. The resulting mechanical properties suggest the suitability of the produced materials for use in thermal insulating applications where high load-bearing capacities are not required. Mechanical or chemical treatment of the waste is recommended for further exploitation of its potential in participating in the alkali activation process.
