Lift slab construction (also called the Youtz-Slick Method) is a method of constructing concrete buildings by casting the floor or roof slab on top of the previous slab and then raising (jacking) the slab up with hydraulic jacks. This method of construction allows for a large portion of the work to be completed at ground level, negating the ...
A finished tilt-up building. Tilt-up, tilt-slab or tilt-wall is a type of building and a construction technique using concrete.Though it is a cost-effective technique with a shorter completion time, [1] poor performance in earthquakes has mandated significant seismic retrofit requirements in older buildings.
Chalk art by kids in the Czech Republic. On September 16–17, 2006, a global event was held to promote peace through sidewalk chalk drawings. [5] Chalk4Peace was a project planned by an artist from Arlington, Virginia named John Aaron, who asked children and teens from the age of eight to age eighteen to participate in groups across the world to draw chalk drawings that would illustrate peace ...
A sidewalk (North American English) [1] [2] [3] or pavement (British English) is a path along the side of a road. Usually constructed of concrete, pavers, brick, stone, or asphalt, it is designed for pedestrians. A sidewalk is normally higher than the roadway, and separated from it by a curb.
The first residential building of slipform construction; erected in 1950 in Västertorp, Sweden, by AB Bygging Later picture of the residential building in Västertorp. Slip forming, continuous poured, continuously formed, or slipform construction is a construction method in which concrete is placed into a form that may be in continuous motion horizontally, or incrementally raised vertically.
In all cases the top surface remains flat, and the underside is modulated: A corrugated slab is designed when the concrete is poured into a corrugated steel tray, more commonly called decking. This steel tray improves strength of the slab, and prevents the slab from bending under its own weight. The corrugations run in one direction only.
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.
Permeable interlocking concrete pavements are concrete units with open, permeable spaces between the units. [ 28 ] : 2 More recently manufacturers have introduced styles with smaller joint allowing for better ADA compliance and still capturing a significant amount of stormwater.
