Polymer concrete. Polymer concrete is a type of concrete that uses a polymer to replace lime -type cements as a binder. One specific type is epoxy granite, where the polymer used is exclusively epoxy. In some cases the polymer is used in addition to portland cement to form Polymer Cement Concrete (PCC) or Polymer Modified Concrete (PMC). [1]
Epoxy. A syringe of "5-minute" epoxy glue, containing separate compartments for the epoxy resin and the hardener. Structure of the epoxide group, a reactive functional group present in all epoxy resins. Epoxy is the family of basic components or cured end products of epoxy resins.
Finally, coatings may also be applied on the surface to consolidate small surface features or to improve the surface quality of the part. Typical materials used for coatings are polyester or epoxy resin. [12] 3D concrete printing with binder jetting technologies has been demonstrated at large scale by Enrico Dini with D-Shape. [13]
Geopolymer. A geopolymer is a vague pseudo-chemical term used to describe inorganic, typically bulk ceramic -like material that forms covalently bonded, non-crystalline (amorphous) networks, often intermingled with other phases. Many geopolymers may also be classified as alkali-activated cements or acid-activated binders.
A binder or binding agent is any material or substance that holds or draws other materials together to form a cohesive whole mechanically, chemically, by adhesion or cohesion. More narrowly, binders are liquid or dough-like substances that harden by a chemical or physical process and bind fibres, filler powder and other particles added into it.
Concrete is a mixture of coarse (stone or brick chips) and fine (generally sand and/or crushed stone) aggregates with a paste of binder material (usually Portland cement) and water. When cement is mixed with a small amount of water, it hydrates to form microscopic opaque crystal lattices encapsulating and locking the aggregate into a rigid shape.
