More Information
Summary:The invention discloses a road base material adopting pyrite tailings. The road base material comprises the following components in parts by mass: 10-40 parts of a novel unfired low-carbon cementing material curing agent, 60-90 parts of a stabilized material and water, the novel baking-free low-carbon cementing material curing agent comprises the following components in percentage by mass: 15-40% of steel slag powder, 40-70% of slag powder, 5-30% of byproduct gypsum and a special exciting agent, wherein the special exciting agent comprises the following components: sodium carbonate, sodium sulfate and/or sodium stearate; the stabilized material is pyrite tailings. The invention further discloses a preparation method of the roadbase material adopting the pyrite tailings. The preparation method has the beneficial effects that the dual theories of alkali excitation and sulfate excitation are utilized, the synergistic coupling excitation effect between solid wastes is fully exerted, a hydration hardening communit
