Lighting strike-level temperatures test concrete block walls

From the National Concrete Masonry Association and Sandia National Laboratories … High-power electrical discharges can trigger explosions reaching upward of 35,000°C, vaporizing steel and spewing hot metal particles. In a power plant, such high-energy arc faults can quickly spread, a condition researchers at Sandia National Laboratories, Albuquerque, N.M., are trying to prevent by finding a new way to peer into flames approximating lightning strike heat. Those flames bear useful information that can help keep power plants operating safely, researchers suggest.

Developer demonstrates speed, labor efficiency in 3D-printed home

An industrial and consumer 3D printing equipment developer reports completion of the world’s largest permitted project of its kind to date: A three-bedroom home whose foundation, exterior walls and interior partitions were printed in 48 hours over an eight-day window with temperatures in the 30s at a cost below $6,000. SQ4D Inc. deployed its Autonomous Robotic Construction System (ARCS) for the 1,900-sq.-ft., Calvern, N.Y. project.

Data science streamlines concrete mix design, curing, QC evolution

Solidia Technologies has teamed with start-up Uncountable to build a data analysis platform expediting research & development and commercial application surrounding the former company’s low carbon cement and concrete. Using data science, machine learning and artificial intelligence, Uncountable’s web platform equips Solidia and its customers to improve production and finished elements or structures by trialing myriad concrete formulations without years of experimentation. It serves as a bridge between the company’s Piscataway, N.J. headquarters lab and optimization at customer facilities during pilot and commercial phases.
