The American Concrete Institute (ACI) announced record-breaking registration for its 24 Hours of Concrete Knowledge event, with nearly 2,500 registrants and more than 1,000 live attendees. For the sixth straight year, this event gathered students and experts from around the world for 24 continuous hours of collaborative and innovative learning.

Learning objectives: 1. Identify the three main types of polymeric concrete, including polymer concrete (PC), polymer-modified concrete (PMC), and polymer-impregnated concrete (PIC), and explain how they differ based on the type and extent of polymer binder use. 2.

When the American Concrete Institute (ACI) Student Chapter at King Khalid University (KKU) launched in 2025, it made an immediate impact. In a single semester, the Chapter delivered 15 events, engaged 1,800 total participants, mobilized 45 active team members, and published 100 social media posts, all while completing five applied engineering projects. For a Chapter in its inaugural term, that’s an impressive beginning.
