Pegna's research would later become the basis for binder jetting, or powder based 3D concrete printing. In 1998, Behrokh Khoshnevis at the University of Southern California developed Contour Crafting, which was the first layered extrusion device for concrete.
Calcium carbonate powder accounts for 97% of the composition will bring white/opaque products more whiteness. So manufacturers can reduce the usage of white masterbatch. With a smaller percentage, calcium carbonate powder can be used for color products. In addition, it brings final plastic products a more bright and more glossy surface. [8]
Cement powder in a bag, ready to be mixed with aggregates and water. [1] Cement block construction examples from the Multiplex Manufacturing Company of Toledo, Ohio, in 1905 A cement is a binder , a chemical substance used for construction that sets , hardens, and adheres to other materials to bind them together.
Concrete or beton is a composite material composed of aggregate bonded together with a fluid cement that cures to a solid over time. Concrete is the second-most-used substance in the world after water, [1] and is the most widely used building material. [2] Its usage worldwide, ton for ton, is twice that of steel, wood, plastics, and aluminium ...
Unlike regular concrete, ECC has a tensile strain capacity in the range of 3–7%, [1] compared to 0.01% for ordinary portland cement (OPC) paste, mortar or concrete. ECC therefore acts more like a ductile metal material rather than a brittle glass material (as does OPC concrete), leading to a wide variety of applications.
The most common use for portland cement is in the production of concrete. [20] 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.

Stamped concrete is an architectural concrete that has a superior surface finish. After a concrete floor has been laid, floor hardeners (can be pigmented) are impregnated on the surface and a mold that may be textured to replicate a stone / brick or even wood is stamped on to give an attractive textured surface finish.
