Oct 19, 2017· A group of researchers from ETH Zurich have designed and built a 25-foot-tall prototype for an ultra-thin, lightweight, and double-curved, concrete roof, that is set to be used in a residential construction project next year. With an average thickness of nearly 2", the structure varies between 1.2"-thick on the edges to 4.7"-thick at the roof's support areas.

Comparison Chart of Overlay Systems Concrete Refinishing. There are a wide variety of overlay systems available for refinishing concrete flatwork, ranging from ultra-thin systems (also called "microtoppings" or "skim coats") that can be applied in layers as thin as a credit card to floor underlayments that go on at thicknesses of up to an inch

Price Ultra-thin overlays are an affordable way to reap the many advantages of concrete pavement, and it is competitively priced with asphalt overlays. Ease of placement Surface preparation is minimal, and paving can be accomplished with the same equipment used in conventional concrete installation.

It might also be wise to add 3 pounds of synthetic fibers per cubic yard of patching mix, similar to the procedure used for ultra-thin whitetopping, so, if the patch fails, small chunks of concrete won't be dislodged. The other possibility is use of proprietary patching mixes or admixtures made specifically for repair applications.

Capping Compound is used for even load distribution in concrete strength testing. The compounds melt quickly and comply with ASTM and AASHTO standards. Available in ingot or ultra-thin flake compounds. Vertical Cylinder Cappers are available for 3in, 4in, and 6in (76, 102 and 152mm) diameters and meet AASHTO T 231 and ASTM C617 standards.

An Ultra-Thin Continuously Reinforced Concrete Pavement (UTCRCP) is a composite structure that makes use of a high strength fibre-reinforced concrete. Originating from Europe, the South African National Roads Agency Ltd (SANRAL) embraced the principles of UTCRCP and developed the technology further to suit local requirements and environment. The

In recent years, ultra-thin whitetopping (UTW) has evolved as a viable rehabilitation technique for deteriorated asphalt cement concrete (ACC) pavement. Numerous UTW projects have been constructed and tested, enabling researchers to identify key elements contributing to their successful performance. These elements include foundation support, the interface bonding condition, portland cement

Whitetopping of airport runways and aprons has been performed in the past, but only at thicknesses of 5 inches or greater. Ultra-thin overlays are generally less than 4 inches thick. A design feature of the ultra-thin overlay was the 4-foot, 2-inch joint spacing.

“A second, exterior layer of the concrete sandwich structure encloses the roof, onto which thin-film photovoltaic cells are installed. Eventually, thanks to the technology and an adaptive solar facade, the residential unit is expected to generate more energy than it consumes.”

Researchers from Swiss university ETH Zurich have built a prototype of an ultra-thin, curved concrete roof using innovative digital design and fabrication methods. The self-supporting, doubly curved shell roof has multiple layers, with the heating and cooling coils and insulation installed over the inner concrete

Typically, the paving cost for concrete is a little higher than the paving cost for asphalt. But in many scenarios, funding a concrete road project can be difficult because concrete is not always considered a short-term solution. Repairing a concrete road often leads to replacing a

As growth ensued, Willis moved his operation to Congerville, Illinois in 1968. He continued to increase his services to his customers to include masonry and concrete practices. In 1990, Willis retired and Steve Knapp took ownership. As the customer’s needs increased, Knapp Concrete expanded their services and equipment.

Aug 30, 2018· Created for the ETH NEST HiLo project—a research facility focused on lightweight and adaptive construction—the structure offers thermal regulation, insulation, waterproofing, and power generation supplied via an ultra-thin concrete shell with a thickness ranging between 1 and 2 inches along the edges that is topped with strips of thin film

Ultra-Thin Whitetopping. The aged asphalt taxiway/apron at the New Smyrna Beach Airport in Florida exhibited severe alligator cracking. The airport officials and DOT chose to overlay the area with a concrete ultra-thin whitetopping. Nearly 200,000 sy of pavement was overlaid with 2" to 3.5" of concrete.

Thin lift asphalt overlays can be used to address functional issues, safety issues as well as maintain roadways under all traffic conditions as a pavement preservation technique. Project selection is a key issue for thin asphalt overlays. Thin overlays of structurally sound pavements can last 10 years or more.

The research on this cell will be done as part of a Multi-state Pooled Fund project TPF-5(165) that will use the MnROAD and other test section data to develop a rational design method for thin concrete overlays. Thin Unbonded Concrete Research Page . PCC Surface Characteristics Construction

For years, pavement engineers have used ultra-thin whitetopping (UTW) to rehabilitate old asphalt pavements. In this process, a thin layer of concrete (3 to 4 inches) is bonded to the existing asphalt pavement. The new concrete provides an economical, smooth riding surface that is much stronger and more durable than the old asphalt pavement.
