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.
Slabs are one of the greatest consumers of concrete in many buildings, [14] so reducing the slab mass can make a relatively large difference to the environmental impact of a building's construction. Biaxial slabs may be marginally cheaper than solid slabs, partly due to the lower mass.
Wind gusts in Florida reached 73 mph (117 km/h) on Buck Island. The storm also dropped heavy rainfall, reaching 15.0 in (380 mm) in Wellborn. Trees and power lines were damaged, while a few tornadoes result in modest damage. [118] A teenager died in high seas in Daytona Beach. [119]
It is midway between the village of Goshen and Florida, at the junction of NY 17A and Quarry Road (Orange County Route 68), built into the side of a 580-foot (177 m) hill known as Mount Lookout. In the 1960s, archaeologists digging at the site found caves with artifacts left by hunter-gatherers 12,000 years ago, during the last Ice Age.
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.
A concrete slab is a common structural element of modern buildings, consisting of a flat, horizontal surface made of cast concrete. Steel-reinforced slabs, typically between 100 and 500 mm thick, are most often used to construct floors and ceilings, while thinner mud slabs may be used for exterior paving (see below). [1] [2]
Tabby was used by early Spanish settlers in present-day Florida, then by British colonists primarily in coastal South Carolina and Georgia. [1] It is a man-made analogue of coquina , a naturally-occurring sedimentary rock derived from shells and also used for building.
A waffle slab or two-way joist slab is a concrete slab made of reinforced concrete with concrete ribs running in two directions on its underside. [1]
