Farmington Hills, Mich. — At the 2014 ACI Technical Activities Committee Summer Meeting, in Waimea, Hawaii, two new ACI technical committees were formed — Committee 240, Natural Pozzolans, and Committee 241, Nanotechnology of Concrete.

Natural pozzolan production in North America is expected to continue to increase, and although ACI does have a Committee 232, Fly Ash, Natural and Processed Pozzolans in Concrete, it was decided that because the use of natural pozzolan materials may differ significantly from the classical applications of fly ash, that the former needed to be addressed separately, and a separate committee should be established.

This new committee will allow for better focus and alignment of committee topics/projects that specifically apply to natural pozzolans. In addition, actions related to reporting on the use of natural pozzolans will be expedited by the formation of a new committee dedicated to Natural Pozzolans. Committee 240, Natural Pozzolans is chaired by Robert Neal.

Committee 241’s goals are to gather and disseminate information on the nanotechnology of concrete including: update the terms, and report, related to nanotechnology of concrete; develop guidelines and Tech-Notes on measurements and/or prediction of the performance of concrete with nano-additives; report on investigation, modification and modeling of the structure of cement-based materials at nano-level; report on application of nano-materials to improve the performance and sustainability of cement and concrete; report on development of smart materials and sensors based on nanotechnology for application in concrete; foster discussion on the selection of a reference material for comparing the effects of nano-materials; report on health, safety and environmental issues related to nanotechnology of concrete. Committee 241, Nanotechnology of Concrete, is chaired by Konstantin Sobolev.

The American Concrete Institute relies on the work of over 3,000 committee volunteers to develop the latest codes and reports related to concrete. Learn more about joining an ACI committee.

ACI Committee Members consist of professionals from all experience levels and all sectors of the concrete industry. While some of the members serving on committees have been active many years, students, young professionals, and industry veterans from across the globe are equally encouraged to join. It is through diversity that ACI strives to develop and disseminate the most advanced concrete knowledge, and ACI encourages you to participate by joining a committee.

Both new committees are scheduled to meet at the ACI Fall Convention in Washington D.C., October 26-30, 2014.
