Outline
To improve the added value utilization rate of reservoir sediment in the field of construction materials, the reservoir sediment was used as auxiliary cementitious material to prepare pervious concrete. The results show that with the increase of reservoir sediment content, the compressive strength of the specimens will decrease, and the permeability will increase. With the extension of mechanical activation time, the compressive strength of the specimen increases and the permeability decreases. When the water cement ratio is 0.3, the mechanical activation time is 45 min, the 28 d compressive strength of the prepared pervious concrete can reach 21.44 MPa, and the permeation coefficient is 0.56 mm/s. The results of this study can provide reference for the resource utilization of reservoir sediment in the field of building materials.
