Polymer-cement shotcrete at the construction of the Dangara hydraulic tunnel

Hydrotechnical Construction Aims and scope

Conclusions

  1. 1.

    Polymer-cement shotcrete (gunite) has a number of advantages in comparison with ordinary shotcrete — increased elasticity (low modulus of deformation), high impermeability and adhesiveness to rocks and concrete, resistance to corrosive effects, nontoxicity of the polymer used, and simplicity of the technology of adding latex to the coating material.

  2. 2.

    The addition of polymer makes it possible to reduce the thickness of the coating by at least half while preserving the strength and operating characteristics of the support, which provides a high cost effectiveness of using polymer-cement shotcrete.

  3. 3.

    It is expedient to recommend the wide use of highly effective polymer-cement compositions on a base of synthetic latex SKS-65GP in hydrotechnical construction.
