An experimental study on water purification performance of modified volcanic rock ecological concrete [PDF]

Scientific Reports
Eco-concrete is an engineered porous material, often used in pervious pavement and slope protection. Volcanic rock, due to its loose and porous structure, can absorb pollutants and improve the performance of eco-concrete.
