  2. 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 ...

  3. Soil stabilization - Wikipedia

    en.wikipedia.org/wiki/Soil_stabilization

    Such non-traditional stabilizers include polymer-based products (e.g. cross-linking water-based styrene acrylic polymers that significantly improve the load-bearing capacity and tensile strength of treated soils), Copolymer Based Products, fiber reinforcement, calcium chloride, and Sodium Chloride.

  4. Pavers (flooring) - Wikipedia

    en.wikipedia.org/wiki/Pavers_(flooring)

    This raised concrete sand helps lock the pavers in place so that they can handle more weight. [9] [10] Concrete sand is a more preferable bedding layer than rock dust. Because rock dust retains rather than drains water, it prevents polymeric sand from drying and curing.

  5. Dilatancy (granular material) - Wikipedia

    en.wikipedia.org/wiki/Dilatancy_(granular_material)

    Dilatancy of a sample of dense sand in simple shear. The phenomenon of dilatancy can be observed in a drained simple shear test on a sample of dense sand. In the initial stage of deformation, the volumetric strain decreases as the shear strain increases. But as the stress approaches its peak value, the volumetric strain starts to increase.

  6. Geosynthetics - Wikipedia

    en.wikipedia.org/wiki/Geosynthetics

    Geofoam is a polymeric product created by processing polystyrene into a foam consisting of many closed cells filled with air and/or gases. The skeletal nature of the cell walls resembles bone-structures made of the unexpanded polymeric material.

  7. 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.

  9. Geogrid - Wikipedia

    en.wikipedia.org/wiki/Geogrid

    The development of methods of preparing relatively rigid polymeric materials by tensile drawing, [2] in a sense "cold working," raised the possibility that such materials could be used in the reinforcement of soils for walls, steep slopes, roadway bases and foundation soils. The principal function of geogrids is for reinforcement.
