Laboratory cylinder testing wasa part of a recent researchprogram on high strengthconcrete. This three-year, indus-try sponsored programconfirmed the applicability ofmost of the standards governingconventional strength concrete.(See "Research study resultsannounced," ConcreteInternational, January 1993, p.68-70.)

Institute HonorsOne ssociat·on

Twenty-five individuals and theConcrete Reinforcing Steel in-stitute were honored with pres-tigious awards of the American

Concrete Institute during the March 28-April 2 convention in Vancouver,British Columbia, Canada.

The awards included three of Hon-orary Membership, ACl's highest awardwhich recognizes "persons of eminencein its field, or those who perform extra-ordinary meritorious service" to the In-stitute. Since this honor was establishedin 1926, 135, including the three cited inthe Vancouver, have been elected toHonorary Membership.

One of the three, Peter D. Courtois,who died in April 1992, was recognizedposthumously at the Awards Breakfastin Vancouver. Prior to his death, COllr-tois was nominated for this award byACI's Honorary Membership Com-mittee and the Board of Direction lastfall agreed that the presentation shouldstill be made.

ACl's other new Honorary Membersare:

Emery Farkas, Cambridge, Mass., apast president of the Institute.

Yves Saillard, Paris, France.In one of his final acts before con-

cluding a one-year term as president ofthe Institute, James G. MacGregorhanded out the honors at the annualAwards Breakfast during the springmeeting.

In addition to the Honorary Member-ships and other individual awards, Mac-Gregor also recognized the 22 ACImembers newly elected to the rank of

Fellow. (See article on "New ACI Fel-lows" in the March 1993 issue of Con-crete International.)

Fifty year membership honors andthe annual awards to Institute chapterswere also presented by MacGregor inthe Canadian city.

The Concrete Reinforci1w Steel In-stitute, Schaumburg, m., received AcrsCharles S. Whitney Award. Given inmemory of an ACI past president, theWhitney honor recognizes "noteworthyengineering development work in con-crete design or construction" and is gen-

erally presented to a firm, university, orgovernmental agency rather than an in-dividual.

In addition to the ACI honors, theArthur J. Boase Award of the Rein-forced Concrete Research Council washanded out by President MacGregorduring the Awards Breakfast. Thisjs. anaward of RCRC, an agency of theAmerican Society for Civil Engineers,and is customarily presented at the In-stitute's Awards Breakfast; the recipientin Vancouver was James O. Jirsa,former ACI Board of Direction member.

In 1990, the Concrete ReinforcingSteel Institute Fund, Inc., (CEFI) wasestablished as a separate corporation toraise funds for financial assistance tostudents; during a 10 year period, 1981through 1991, 59 graduate students re-ceived fmancia1 aid from CRSI.

CRSI and AC1 have had a long andmutually beneficial working relation-ship dating back to the late 1920s whenthe two associations collaborated in thedrafting of a standard building code.This joint venture led to ACI's sole re-sponsibility for the drafting and publi-cation of the existing Building Code Re-quirements for Reinforced Concrete.

A similar occurrence took place in1947 when CRSI published its Manualof Standard Practice for Detailing Re-inforced Concrete Structures. This doc-ument became the basis for the ACI 315detailing standard and evolved into thecurrent Detailing Manual (SP-66.)

A variety of technical books, manuals, and reports are published by CRSI, as il-lustrated in this photo. In recent years, the Institute's publications program hasbeen expanded to include computer software for the design of concrete struc-tures and pavements.

CRSI now has a staff of 17, directedby President Victor A. Walther, 11'.David P. Gustafson, CRSI's technicaldirector who serves on ACI's TechnicalActivities Committee and several tech-nical committees, was slated to receivethe award on behalf of CRSI at the Van-couver convention.
