Expansive soil foundation modifying agent and modifying construction method
The invention provides an expansive soil modifying agent. The expansive soil modifying agent is adhesive cement prepared by mixing waste rubber powder, ardealite and water; the mass ratio of the waste rubber powder to the ardealite powder is 20: 80-30: 70; and the mass sum of the waste rubber powder and the ardealite powder is 6-7% of the total mass of the adhesive cement. The modifying agent has the following beneficial effects: compared with a general lime modifying agent, the expansive soil modifying agent combines physical and chemical methods, so that the modifying effect is better, the water stability of expansive soil can be largely increased, the foundation dilatation deformation is prominently decreased, and the duration and the stability are kept.
