Hybrid fiber reinforced concrete material and preparation method thereof
The invention discloses a hybrid fiber reinforced concrete material and a preparation method thereof. The invention relates to the field of building engineering materials. The building material is prepared from the following components in parts by mass: 139 parts of water, 290 parts of cement, 683 parts of sand, 1034 parts of stone, 65 parts of fly ash, 65 parts of mineral powder, 4.2 parts of a water reducing agent, 180 parts of steel fiber and 4.5 parts of basalt fiber. The hybrid fiber reinforced concrete material prepared according to the mixing ratio provided by the invention has the advantages of high shear strength, axial tensile strength, four-point bending strength and splitting tensile strength, and the 28d cubic compressive strength of the hybrid fiber reinforced concrete material is 75.4 MPa, the axial compressive strength is 51.0 MPa, the axial tensile strength is 4.33 MPa, the splitting tensile strength is 5.2 MPa, and the compressive strength of the hybrid fiber reinforced concrete material is 8.2 MPa. The shear strength is 11.9 MPa, the peak strength of a four-point bending test is 8.79 MPa, and the shear strength and the peak strength are both higher than those of plain concrete and hybrid fiber concrete as a contrast.
