The American Concrete Institute (ACI) is currently seeking submissions for sessions taking place during the ACI Fall 2011 Convention and ACI Spring 2012 Convention. More information about current Calls for Papers can be found by visiting www.CallforPapers.concrete.org.

Architectural Concrete in Hot Weather
ACI Committee 305, Hot Weather Concreting, seeks submissions for the technical session "Architectural Concrete in Hot Weather," taking place at the ACI Spring 2012 Convention, March 18-22, in Dallas, Texas.

Participants are invited to submit presentations focused on the production/placement of architectural concrete in hot weather.

Abstracts of no more than 500 words, along with presentation title, author name(s), and contact information should be sent to Terry Harris at terry.harris@grace.com or Jonathan Poole at jpoole@CTLGroup.com no later than June 1, 2011.

Notable Concrete in Cincinnati and Vicinity
ACI Committee 124, Concrete Aesthetics, and the Cincinnati Chapter of the American Institute of Architects seek submissions on "Notable Concrete in Cincinnati and Vicinity" for the ACI Fall 2011 Convention, Oct. 16-20, in Cincinnati, Ohio.

Participants are invited to send submissions of notable concrete in the Cincinnati area. Significance may be historical, aesthetic, functional, structural, construction-related, unusual use or application, or simply personal affection.

Descriptions of up to 100 words, along with location, image, and contact information should be sent to Michael Paul at mpaul@duffnet.com no later than July 1, 2011.

Concrete Piles in Marine Structures in Seismic Regions
ACI Committee 543, Concrete Piles, Committee 357, Offshore and Marine Concrete Structures, and Committee 423, Prestressed Concrete seek submissions for the technical session "Recent Advances in the Design of Prestressed Concrete Piles in Marine Structures in Seismic Regions," taking place at the ACI Spring 2012 Convention, March 18-22, in Dallas, Texas.

Participants are invited to submit presentations related to the latest procedures and experimental evidence related to the study of slenderness effects on pile capacity; design and detailing of pile-deck connections; development of fragility functions for pile-deck connections; ductility evaluation; multi-axial loading effects; shear and torsional response; interaction with soil; serviceability design; and strengthening/rehabilitation of prestressed concrete piles in piers, wharves, and marine infrastructure subjected to lateral loads stemming from either seismic activity or the berthing/mooring of vessels.

Abstracts of more than 500 words, along with presentation title, author name(s), and contact information should be sent to Carlos Ospina at carlos.ospina@abam.com no later than July 18, 2011.
