2. Precast concrete - Wikipedia

   en.wikipedia.org/wiki/Precast_concrete

   Precast concrete molds can be made of timber, steel, plastic, rubber, fiberglass, or other synthetic materials, with each giving a unique finish. [3] In addition, many surface finishes for the four precast wall panel types – sandwich, plastered sandwich, inner layer and cladding panels – are available, including those creating the looks of ...

3. Formwork - Wikipedia

   en.wikipedia.org/wiki/Formwork

   A matching form will be placed on the opposite side to create the space to pour concrete into. Formwork is molds into which concrete or similar materials are either precast or cast-in-place. In the context of concrete construction, the falsework supports the shuttering molds. In specialty applications formwork may be permanently incorporated ...

4. Casting - Wikipedia

   en.wikipedia.org/wiki/Casting

   Plaster and other chemical curing materials such as concrete and plastic resin may be cast using single-use waste molds as noted above, multiple-use 'piece' molds, or molds made of small rigid pieces or of flexible material such as latex rubber (which is in turn supported by an exterior mold). When casting plaster or concrete, the material ...

5. Form liner - Wikipedia

   en.wikipedia.org/wiki/Form_liner

   When the masterwork is finished, a cast is made using synthetic liquid rubber, and from this cast, form liners are produced in the reverse image of the original. A form liner panel is placed on the inside of a concrete forming system before the concrete has been poured and acts as a mold for the concrete to be formed against. Once the concrete ...

6. Plaster mold casting - Wikipedia

   The mold is then baked, between 120 °C (248 °F) and 260 °C (500 °F), to remove any excess water. The dried mold is then assembled, preheated, and the metal poured. Finally, after the metal has solidified, the plaster is broken from the cast part. The mold is usually damaged from the metal so reusing is usually not done.

7. Portland cement - Wikipedia

   en.wikipedia.org/wiki/Portland_cement

   The most common use for portland cement is in the production of concrete. [17] Concrete is a composite material consisting of aggregate (gravel and sand), cement, and water. As a construction material, concrete can be cast in almost any shape desired, and once hardened, can become a structural (load bearing) element.
