Basalt fiber pervious concrete material for seasonal frozen regions and preparation method of basalt fiber pervious concrete material
The invention provides a basalt fiber pervious concrete material for a seasonal frozen region and a preparation method thereof, and belongs to the technical field of novel pavement materials for road engineering. The basalt fiber pervious concrete material for the seasonal frozen region, provided by the invention, is prepared from the following components in parts by weight: 1545 to 1610 parts of aggregate, 395 to 425 parts of cement, 1 to 5 parts of basalt fiber, 20 to 23 parts of silica fume, 1.3 to 2.3 parts of water reducing agent and 125 to 140 parts of water. According to the basalt fiber permeable concrete material for the seasonal frozen region, the compressive strength is 25.20 MPa, the splitting tensile strength is 3.53 MPa, the permeation coefficient is 6.31 mm/s, the mass loss rate is 0.14% and the compressive strength loss rate is 2.81% after 25 times of freezing and thawing cycles, and the mass loss rate is 0.24% and the compressive strength loss rate is 4.78% after 50 times of freezing and thawing cycles. The water permeable brick has good water permeability, high strength and excellent freezing resistance.
