  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. 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.

  4. Curing (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Curing_(chemistry)

    Curing is a chemical process employed in polymer chemistry and process engineering that produces the toughening or hardening of a polymer material by cross-linking of polymer chains. [1] Even if it is strongly associated with the production of thermosetting polymers , the term "curing" can be used for all the processes where a solid product is ...

  5. Binder (material) - Wikipedia

    en.wikipedia.org/wiki/Binder_(material)

    Sand is added to improve compressive strength, hardness and reduce shrinkage. The binding property of clay is also used widely to prepare shaped articles (e.g. pots and vases) or to bind solid pieces (e.g. bricks). In composite materials, epoxy, polyester or phenolic resins are common.

  6. 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.

  7. 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.

  8. Linear low-density polyethylene - Wikipedia

    en.wikipedia.org/wiki/Linear_low-density...

    The lower shear sensitivity of LLDPE allows for a faster stress relaxation of the polymer chains during extrusion, and, therefore, the physical properties are susceptible to changes in blow-up ratios. In melt extension, LLDPE has lower viscosity at all strain rates. This means it will not strain harden the way LDPE does when elongated.

  9. Dilatant - Wikipedia

    en.wikipedia.org/wiki/Dilatant

    Sand that is completely soaked with water also behaves as a dilatant material — this is the reason why when walking on wet sand, a dry area appears directly underfoot. Rheopecty is a similar property in which viscosity increases with cumulative stress or agitation over time. The opposite of a dilatant material is a pseudoplastic.
