Red mud phosphogypsum hydraulic road base course, red mud phosphogypsum hydraulic road base course material and preparation method of red mud phosphogypsum hydraulic road base course material
The present invention discloses a red mud phosphogypsum hydraulic road base course, a red mud phosphogypsum hydraulic road base course material and a preparation method of the red mud phosphogypsum hydraulic road base course material, and relates to the field of road engineering construction. The preparation method comprises: weighing 10-50% of phosphogypsum and 90-50% of red mud, and uniformly mixing and strring to obtain a primary mixing material; weighing 85-92% of the primary mixing material and 15-8% of ordinary Portland cement, and uniformly mixing and strring to obtain a premix; and weighing 99.7-99.95% of the premix and 0.3-0.05% of a hydraulic curing agent, uniformly mixing and strring to obtain a mixture, and controlling the water content of the mixture to 14-18% to obtain the base course material, wherein the hydraulic curing agent is obtained by mixing the following components by mass: 40-80% of an elastic styrene-acrylic emulsion, and 60-20% of nanometer silicon sol. According to the present invention, the road base course is prepared by using the road base course material according to the standard road base course construction method; the red mud and the phosphogypsum are used to produce the road base course material, such that the pollution of the red mud and the phosphogypsum on the environment is reduced, and the waste is turned into treasure; and the formed road base course has characteristics of strong cracking resistance, corrosion resistance, and long service life.
