The American Concrete Institute (ACI) and the Post-Tensioning Institute (PTI) are partnering to increase design efficiency of structural post-tensioned concrete structures. While the two organizations and their members have worked collaboratively for decades, this partnership formalizes efforts through the new joint ACI-PTI Committee 320, Post-Tensioned Structural Concrete Code, ACI said.
Due to local, state, and federal regulations, and to protect the health and safety of attendees, the American Concrete Institute (ACI) is transitioning the ACI Concrete Convention from an in-person event in Raleigh, North Carolina, to a fully virtual event. The ACI Virtual Concrete Convention will be held from October 25 to 29.
Kamp C, a Belgium-based provincial center for sustainability and innovation in construction, has printed a house using the largest 3D concrete printer in Europe. The 90-m2 (969-sf) dwelling was printed in one piece with a fixed printer. This is a world first, according to Kamp C.
Over the past few decades, construction has taken an increased role in public safety and security. “Use at your own risk” is still true, but good site design is expected to mitigate those risks. Bollards have taken a larger role in offering protection or guidance.
