Thin‐film transistor liquid crystal display (TFT–LCD) waste glass comprises mainly SiO2 and Al2O3, which are suitable raw materials for geopolymer. This study investigates the effects of the amount of foam agents on the properties of waste glass‐based cellular geopolymer. In this investigation, samples underwent a series of tests to determine their quality, including mechanical characterization, compressive strength, flexural strength, fire resistance, thermal conductivity, Fourier transform infrared spectroscopy, and scanning electron microscopy. The experimental results show that the mechanical strength and thermal conductivity decreased with the addition of foam agents, indicating that foam agents can reduce the thermal transfer. The pore volume increased with the amount of increase in foam agent. These results indicated that the amount of foam agent has a more substantial effect than waste glass replacement in geopolymers.
