Trade-Off Between Permeability and Compressive Strength for Aerated Concrete-Based Material with Fly-Ash Under High Pressure

Coal seam gas will seriously threaten the safety of mining. The stability of drainage borehole determines the safety of both mining and utilization of coal seam gas. However, the borehole will collapse, leading to the failure of gas drainage. A porous and firm low-cost aerated concrete-based materia...
