Concrete to Replace Asphalt in $355m JFK Runway Refurb
2 days Funding of US$355m (£270m) has been allocated for a project that includes replacing asphalt with concrete at a key runway at New York’s John F Kennedy International Airport.
Use of concrete instead of typical asphalt is expected to minimise future maintenance impacts by giving the runway a life of up to 40 years, compared with asphalt’s 10-12 years. The Port Authority of New York & New Jersey (PANYNJ) project also includes the addition of a new high-speed taxiway.

Work of Nuclear Reactor in Belgium Over Poor Concrete Quality – Operator
BRUSSELS (Sputnik) – A degradation in concrete quality was discovered at Tihange 2 nuclear power unit in southern Belgium, which was temporarily stopped in September for repairs and maintenance, Engie’s Belgian subsidiary Electrabel, the operator of all nuclear power plants in the country, said the VRT broadcaster on Wednesday.
The issue was detected in the ceiling of a five-story so-called “bunker building,” which houses the reactor’s emergency systems, he specified.
According to Sageman, due to the ongoing repair work, the reactor will be restarted no earlier than June 2019.

New Micron-sized Calcium Silicate Spheres Could Lead to Stronger and Greener Concrete
To researchers, the spheres represent building blocks that can be made at low cost and promise to mitigate the energy-intensive cement-creation techniques. Cement is the most common binder in concrete.
The researchers formed the spheres in a solution around nanoscale seeds of a common detergent-like surfactant. The spheres can be prompted to self-assemble into solids that are stronger, harder, more elastic, and more durable than ubiquitous Portland cement.

Construction using concrete reinforced with renewable materials
Tomorrow’s building material is here today. Textile-reinforced concrete (TRC) is durable, formable in diverse shapes and suitable for lightweight construction. As the name suggests, conventional TRC is reinforced with carbon or glass-fibre fabrics rather than steel. A research team at the Fraunhofer Institute for Wood Research, Wilhelm-Klauditz-Institut WKI is now replacing these fabrics with eco-friendly natural fibres.
These alternatives rival conventional concrete’s performance, but leave a smaller carbon footprint, and cost less to make. Researchers will present a prototype of a natural fibre-reinforced concrete bridge at the BAU 2019 trade fair in Munich on January 14 to 19, 2019.

Firefighters Rescue Sheep Stranded 14ft Down Concrete Bunker
Three fire crews including the rescue tender were called to Cleehill at about 1pm.
They used a short extension ladder and a carry sheet to rescue the sheep, which was 14ft inside the bunker.
Shropshire Fire and Rescue Service said the sheep was not injured.
