Study on composition analysis of foaming agents used in backfilling high-strength lightweight fluidized soil

This paper studies the pollutants released by the foaming agent used in the green and low carbon backfill material of high strength and light fluid soil, which can effectively solve the problem of "bridge jump". The results showed that the concentrations of total volatile organic compounds, benzene, toluene + xylene and free formaldehyde in the pollutants were all within the qualified range. The concentration of non-methane total hydrocarbon in the pollutants increases with the increase of temperature. The concentration of non-methane total hydrocarbon in the pollutants is 3.90mg/m3 at 180°C, which is within the allowable range. During production and use, attention should be paid to ventilation and monitoring.
