Project Ideas

• Concrete Patio Furniture using Silicone Molds for Flat Castings
  • Similar to PlayaTech plywood flatpack furniture
  • Maybe not great because two-sided molds for concrete sound challenging
  • Maybe make a tabletop, bench seat, or bench back, where one side is unseen
• Cylinder Fountain
  • Concrete Form Tube
  • Fiber Mesh x 2
  • Jute Rope: https://www.amazon.com/dp/B08BR57D13

Formulations

Ratios

• Dryer mix is stronger, too wet leaves voids when the water evaporates.
  • Plasticizers act like water, but don't evaporate.
• Aggregate:Portland
  • 1:1 super strong, super expensive
  • 10:1 super weak, super cheap (super light, if using vermiculite or perlite)
  • 2:1 / 3:1: normal

Ingredients

• Portland Cement
  • S-Type 1/2: Uses lime, weighs 78 pounds per bag, more sticky, less compressive strength.
  • Standard: 96 pounds per bag, less sticky, more compressive strength.
  • Or use standard and add lime (3 portland : 1 lime by volume)
• Pumice, Vermiculite, Perlite
  • Light Weight Aggregate

Ferrocement is a type of thin reinforced concrete made with a closely spaced, multiple layers of wire mesh or fine rods, which is then impregnated with a cement-sand mortar. In addition to cement and sand, several additives can be used in ferrocement to enhance its properties. Here are some common additives, their purposes, and typical quantities:

1. Water:
   • Purpose: Essential for the hydration of cement and to create the paste that binds the aggregates.
   • Quantity: Water-cement ratio typically ranges from 0.4 to 0.6 by weight.
2. Admixtures:
   • Types and Purposes:
     • Plasticizers (Water-reducing agents): Improve workability without adding more water. Typical dosage is 0.1% to 0.4% of cement weight.
     • Superplasticizers (High-range water reducers): Allow for significant reductions in water content, improving strength and durability. Dosage can range from 0.5% to 3% of cement weight.
     • Retarders: Slow down the setting time of the cement, useful in hot climates or for complex shapes. Dosage usually around 0.2% to 0.6% of cement weight.
     • Accelerators: Speed up the setting and hardening process, useful in cold climates. Dosage varies, often around 1% to 2% of cement weight.
     • Air-entraining agents: Introduce tiny air bubbles to improve freeze-thaw resistance. Typically used at 0.05% to 0.2% of cement weight.
3. Fibers:
   • Purpose: Improve tensile strength, crack resistance, and overall durability.
   • Types and Quantities:
     • Steel fibers: 0.5% to 2% by volume.
     • Glass fibers: 0.1% to 0.5% by volume.
     • Polypropylene fibers: 0.1% to 0.3% by volume.
4. Pozzolans:
   • Purpose: Improve durability, reduce permeability, and enhance long-term strength.
   • Types and Quantities:
     • Fly ash: Can replace 15% to 30% of cement weight.
     • Silica fume: Used at 5% to 10% of cement weight.
     • Metakaolin: Typically used at 5% to 10% of cement weight.
5. Silica Sand:
   • Purpose: Used as fine aggregate to improve the workability and finish of the mortar.
   • Quantity: Replaces a portion of the regular sand, often 10% to 30% by volume of the sand component.
6. Lime:
   • Purpose: Improves workability and plasticity of the mortar.
   • Quantity: Typically used at 5% to 10% of the cement weight.
7. Waterproofing Agents:
   • Purpose: Improve water resistance and reduce permeability.
   • Types and Quantities: Dosages vary widely depending on the specific product, usually around 1% to 2% of cement weight.

The exact quantities and combinations of these additives will depend on the specific requirements of the ferrocement application, including desired strength, workability, setting time, and durability.
