Red mud water hard roadbase, roadbase material and preparation method of roadbase material
The invention discloses a red mud water hard roadbase, a roadbase material and a preparation method of the roadbase material, relating to the field of road engineering construction. The preparation method of the roadbase material comprises the steps of weighing 80% to 95% of red mud and 20% to 5% of ordinary portland cement, and mixing and stirring evenly to obtain an elementary mixed material; weighing 99.5% to 99.9% of the elementary mixed material and 0.5% to 0.1% of red mud water rigidness curing agent, mixing and stirring evenly to obtain a gunk, and controlling the moisture content of the gunk to be 14% to 18% to obtain the roadbase material, wherein the red mud water rigidness curing agent is formed by mixing the following components in mass percent: 40% to 80% of elastic styrene acrylic emulsion and 60% to 20% of nano alumina sol, and the solid content of the elastic styrene acrylic emulsion is greater than 55%. The roadbase adopts the roadbase material and is prepared according to a standard roadbase construction method. The red mud is used for producing the roadbase material, thus turning waste into wealth; the formed roadbase is high in crack resistance, difficult to corrode and long in service life.
