Microbial-induced mineralization and cementation of fugitive dust and engineering application

The control of fugitive dust is becoming a hot spot at home and abroad for a time. Due to high energy consumption, large investment, complex operation and likely secondary pollution to the environment, physical and chemical methods are relatively difficult to be applied to the control of fugitive dust in large areas. In response to these aspects, cementitious materials of biological carbonates were prepared to mineralize and cement loose fugitive dust. In this study, fugitive dust could be controlled effectively in that cementitious materials of biological carbonates had superior mechanical properties, such as wind-erosion resistance, rainfall-erosion resistance, moisture and ecological compatibility.307
