Published references are listed at the end of thetext. Re
3、ferences to standard specifications and methods of testing are listed separately.The original manuscript was prepared by Joe W. Kelly, Chair of ACI Committee 311, andrevised over a period of years to achieve a first edition in 1941. The second edition, also in 1941,included a number of corrections a
4、nd minor revisions. The third edition, in 1955, incorporatedmany constructive suggestions from users. The fourth edition, in 1957, brought several sectionsup to date and contained editorial corrections.The fifth edition provided new information on settlement of concrete, shoring and forming,strength
5、 requirements, cold-weather concreting, and shotcrete. The sixth edition primarilyprovided updated information in all chapters, and included editorial and substantive changesthroughout.The seventh edition presented a complete revision of the manual by eliminating sections of theprevious edition cove
6、ring concrete methods no longer in use. Chapters 2, 11, 12, 13, 14, 15(partial), 16, 17, and 18 covered material that was included in the manual for the first time. Theeighth and ninth editions were revised to reflect changes in technology and construction practices.This tenth edition presents an ex
7、tensive revision and update to the text along with new photos,charts, and forms.The committee wishes to thank Anne Balogh for her extensive work in redrafting and unifyingthe previous text in preparation for this edition. Additionally, the committee wishes to express itsthanks to Portland Cement Ass
8、ociation (PCA) for generously providing many of the new photoscontained in the manual and to committee member Michelle L. Wilson who organized and coordi-nated the selection of photos and graphics throughout the document.Finally, the committee wishes to thank Chair George R. Wargo for his efforts in

14、intended to guide, assist, and instruct concrete inspectorsand others engaged in concrete construction and testing, including fieldengineers, construction superintendents, supervisors, laboratory and fieldtechnicians, and workers. Designers may also find the manual to be a valuablereference by using
15、 the information to better adapt their designs to the realitiesof field construction. Because of the diverse possible uses of the manualand the varied backgrounds of the readers, it includes the reasoning behindthe technical instructions.The field of concrete construction has expanded dramatically o
16、ver theyears to reflect the many advances that have taken place in the concreteindustry. Although many of the fundamentals presented in previous editionsof this manual remain relevant and technically correct, this tenth editionincorporates new material to address these advances in technology. A list
17、of only a few of the recent developments in materials, equipment, andprocesses includes: Shrinkage-compensating cement;Increased use of supplementary cementitious materials (SCMs);Polymer-modified mixtures;Self-consolidating concretes;New and refined admixtures;Fiber-reinforced concrete;Epoxy resins
18、;High-capacity and automated concrete production equipment;High-performance and high-strength concrete; andEpoxy-coated and stainless steel-clad reinforcement.The need to cover new issues affecting inspection is the reason ACICommittee 311 continues to revise the ACI Manual of Concrete Inspection.In
19、 preparing this edition of the manual, as with previous editions, thecommittees task was to interpret the policies set forth by other authorizedbodies rather than to make policy on construction practices. The mainemphasis of the manual is on the technical aspects of inspection andconstruction. For f
20、urther information about construction practices, readersare encouraged to refer to the ACI Manual of Concrete Practice.Because the content of this manual is general and broad in nature, nopart of the manual should be included by reference in contract documents.Applicable inspection requirements for
21、each project should be determinedand included in the specifications.Chapter 1Inspection and the inspector, p. 61.1Inspection processes1.1.1Why inspection is needed1.1.2Purposes of inspection1.1.3Owner and contractor inspections1.2Inspector1.2.1Duties1.2.2Education and certification1.2.3Authority1.2.
