2. Sand reinforced polyester composite - Wikipedia

   en.wikipedia.org/wiki/Sand_reinforced_polyester...

   Sand reinforced polyester composites (SPCs), are building materials with sand acting as reinforcement in the composite.Pioneers in using sand reinforced composites include German business men Gerhard Dust and Gunther Plötner, who made sand reinforced composite bricks with polyester resin and hardener to provide emergency relief housing for those affected by the 2010 earthquake in Haiti.

3. Polymer soil stabilization - Wikipedia

   en.wikipedia.org/wiki/Polymer_soil_stabilization

   Synthetic polymers began replacing other chemical binders for soil stabilization in agriculture in the late 20th century. [1] Compared to traditional chemical binders, polymer soil additives can achieve the same amount of strengthening at much lower concentrations – for example, mixtures of 0.5-1% of various biopolymers have strength levels that match or exceed those of 10% cement mixtures ...

   Some renewable technologies are enzymes, surfactants, biopolymers, synthetic polymers, co-polymer-based products, cross-linking styrene acrylic polymers, tree resins, ionic stabilizers, fiber reinforcement, calcium chloride, calcite, sodium chloride, magnesium chloride, and more. Some of these new stabilizing techniques create hydrophobic ...

   Stiff polymer geogrids, with very open apertures, in addition to three-dimensional geocells made from various polymers are also increasingly specified in unpaved and paved roadways, load platforms and railway ballast, where the improved loadbearing characteristics significantly reduce the requirements for high quality, imported aggregate fills ...
