Preparation and characterization of glass foams for artificial floating island from waste glass and Li2CO3

Recycling of waste ceramic foams as fine aggregates in pervious concrete

“…Ceramic foams have become popular porous materials owing to the combination of being lightweight, their incombustibility, heat and sound insulating, as well as being chemically stable. [1][2][3][4][5] These properties have contributed to their increased attention in the extensive production and application of ceramic foam in the elds of thermal and acoustic insulation, 6 in light construction, 7 as an articial oating island carrier 8 and for microwave absorption 9,10 over the past ten years. While vigorously developing the ceramic foam, waste accumulation has progressively formed from discarded ceramic foam, leading to serious impacts on the surrounding environment.…”

Tailoring pore structure and properties of waste-derived ceramic foams for lightweight construction

“…4 The comprehensive use of waste glass is extremely urgent and, consequently, the fabrication of glass CFs from waste glass has generated much interest and has opened a new avenue for the recycling of waste glass. 26,27 Since granite waste, coal gangue, and waste glass contain large amounts of SiO 2 , Al 2 O 3 , alkaline oxide, and alkaline Earth oxide that are similar to the ceramic components, we used three waste sources as raw materials to fabricate CFs using SiC as the foaming agent. The pore structure, the physical and mechanical properties of CFs subjected to different sintering temperatures, and the inuence of the SiC content and additives were investigated.…”

“…Additionally, the waste glass generated annually from the manufacturing of glass and municipal solid waste represents nearly one million ton in China. 26 The major use for waste glass is in the production of original glassware, which is limited because of the contamination risks and the loss of quality. 4 The comprehensive use of waste glass is extremely urgent and, consequently, the fabrication of glass CFs from waste glass has generated much interest and has opened a new avenue for the recycling of waste glass.…”

Numerical Simulation of Thermal Conductivity of Foam Glass Based on the Steady-State Method

“…This type of material is attractive for its high mechanical strength, low thermal conductivity, non-combustion (A-grade flame-retardant material), high softening temperature, good thermal and chemical stability, good sound insulation effect, strong corrosion resistance and is insect-proof. Therefore, it is highly attractive to be used in thermal insulation materials, lightweight filling materials, sound-absorbing materials, and lightweight concrete aggregates in fields like construction, water conservancy and transportation [5,6,7,8,9,10,11,12,13].…”
