Delaminations in concrete floor slabs can be difficult to repair in a cost-effective and timely manner. A newly developed product that uses a two-part hybrid polyurethane with a viscosity similar to water can significantly reduce the difficulty of performing delamination repairs by easily flowing up to 10 ft (3 m) from an injection point and penetrating deep into concrete surfaces. The product also speeds up repair by setting in only 10 minutes, allowing the repair to be checked by sounding only 30 minutes after product placement.

ACI 318 is arguably one of the most influential concrete codes in the world and a primary reason for ACI’s reputation as a leading source of technical information on the use of concrete. The basic framework of the Code was established in 1963 to introduce strength design and has remained basically unchanged ever since. To ensure that the Code continues to serve as a primary resource for the construction industry, ACI Committee 318 has elected to step back and examine the document’s organization. This article presents the case for reorganizing the Code and discusses why it may be prudent to do so at this time.

Before the ACI Spring 2008 Convention, the Technical Activities Committee (TAC) selected 73 Chairs for ACI technical committees and TAC subcommittees.
