3、adelphia,Pa.19103 by American Society for Testing and Materials 1966 Library of Congress Catalog Card Number:65-23472 Printed in Baltimore,Md.April,1966 FOREWORD This publication is a revision and expansion of the report on Significance of Tests and Properties of Concrete and Concrete Aggregates pub
4、lished in 1956.That publication in turn replaced editions of Report on Significance ofTests of Concrete and Concrete Aggregates published in 1935 and 1943.The present report introduces a still broader scope in that the significance of specifications,as well as of the properties and test methods,is d
5、iscussed.Moreover,this report covers several types of materials not referred to in the earlier reports but whose importance has increased greatly since preparation of the 1956 report.As was true for the previous publications in this series,the separate chap-ters have been prepared by individuals sel
6、ected because of their knowledge of the respective subjects and because of their participation in development of pertinent methods of testing and specifications.While independent ex-pression by the authors has been encouraged,individual chapters have been reviewed and the entire report has been coor
7、dinated by a special committee appointed for that purpose by Committee C-9 on Concrete and Concrete Aggregates.The special committee in charge consists of:R.C.Mielenz,The Master Builders Co.,Division of Martin Marietta,Cleveland,Ohio,chair-man;D.L.Bloem,Nat.Ready Mixed Concrete Assn.and Nat.Sand and
