Gypsum concrete is a building material used as a floor underlayment used in wood-frame and concrete construction for fire ratings, sound reduction, radiant heating, and floor leveling. [1] It is a mixture of gypsum plaster, Portland cement , and sand .
Concrete floor polished with 1800 grit. Polished concrete is a multi-step process where a concrete floor is mechanically ground, honed and polished with bonded abrasives in order to achieve a desired level of sheen or gloss. The Concrete Polishing Process. Concrete polishing begins with floor preparation. During this process, the floor is ...
Finlock concrete gutter units are made up of two troughs – one is the visible gutter and the other sits across the cavity wall. The blocks which can range from 8 to 12 inches (200 to 300 mm) can be joined using reinforcing rods and concrete , to form lintels for doors and windows.

The Filigree Wideslab method is a process for construction of concrete floor decks from two interconnected concrete placements, one precast in a factory, and the other done in the field. The method was developed during the late 1960s by Harry H. Wise as a more efficient and economic construction process than conventional cast-in-place technologies.
The advantages of this approach in comparison to beam formwork or modular formwork is a further reduction of labor time and cost. Smaller tables are generally easier to customize around geometrically complicated buildings, (round or non rectangular) or to form around columns in comparison to their large counterparts.
The precast concrete slab has tubular voids extending the full length of the slab, typically with a diameter equal to the 2/3–3/4 the thickness of the slab. This makes the slab much lighter than a massive solid concrete floor slab of equal thickness or strength. The reduced weight also lowers material and transportation costs.
Shotcrete, gunite (/ ˈ ɡ ʌ n aɪ t /), or sprayed concrete is concrete or mortar conveyed through a hose and pneumatically projected at high velocity onto a surface. This construction technique was invented by Carl Akeley and first used in 1907. [1]: 7 The concrete is typically reinforced by conventional steel rods, steel mesh, or fibers.
