Mixture 1

  • 425 grey cement
  • Foaming agent
  • Dental gypsum
  • Iron oxide powder
  • Water
    Mixture: 10 part cement, 1 part foaming agent, 4 part gypsum, 0.5 part iron oxide, X part water(Control this ratio by yourself).
    After adding foaming agent, the mixture should be stired continuously until there are a lot of bubbles.
    This mixtuer hardens after 5-7 days and reach maximum strength after 20 days.
    Compared to ytong, this is more dense and have a slower water dispersion rate(water tower will last longer).
    Final result slightly alkalic.

Mixture 2

  • 425 gray cement
  • Expanding cement
  • Dental gypsum
  • Silicon dioxide powder
  • Iron oxide powder
  • Water
    Mixture: 10 part cement, 1 part expanding agent, 4 part gypsum, 0.5 part silicon dioxide, 0.5 part iron oxide, X part water(Control this ratio by yourself).
    Compared to Mixture 1, this solidifies faster and end up with a higher strength. Have a slower water dispersion rate than the previous mixture. Can add silicon carbide to decrease than chance of nest getting soaked.

Mixture 3

  • 425 gray cement
  • Foaming agent
  • Expanding cement
  • Fine sand
  • Lava rock particles
  • Silicon dioxide powder
  • Iron oxide powder
  • Water
    Mixture: 12 part cement, 0.5 part expanding agent, 1 part expanding agent, 5 part sand, 0.5 part lava rock particles, 0.5 part silicon dioxide, 0.5 part iron oxide, X part water(Control this ratio by yourself).

Mixture 4

  • 425 gray cement
  • Foaming agent
  • Fine sand
  • Silicon dioxide powder
  • Iron chloride waterproofing agent
  • Iron oxide powder
  • Water
    Mixture: 12 part cement, 0.5 part expanding agent, 4 part sand, 1 part silicon dioxide, X part iron chloride waterproofing agent, 0.5 part iron oxide, X part water(Control this ratio by yourself).

Mixture 5

  • Gypsum
  • Polyvinyl acetate binding glue
  • 10% ammonium chloride solution
  • Sand
    Mixture: 9 part gypsum, 7 part polyvinyl acetate, 0.3 part ammonium chloride solution, 2 part sand.
    Solidifies 15-30 minutes. Can be used 4 days later.

Edge Sealing

  1. Lay the nest flat with chamber opening on top.
  2. Mix epoxy resin.
  3. Use a dropper and drop the areas that need to be sealed.
  4. Use polypropylene, polythene, or polyamide sheet and press it on top. Add heavy object on top to make sure it stays flat.
  5. After 24 hours, take off the sheet with a little fore and its complete.
  • This method can ensure there are no cracks between the glass and the nest, so ants won’t be able to stick trash between the glass and the edge.
