7、ability of Concrete and 222 on Corrosion of Metals in Concrete, was held at the AC1 Fall Meeting in San Diego, California in November, 1989. At the opening session I had the pleasure and personal honor of dedicating the symposium to Mr. Paul Klieger. Although Mr. Kliegers many accomplishments are ve

8、ry familiar to his numerous friends and acquaintances in ACI, a brief biographical sketch precedes the preface. Mr. Klieger has been very active in the work of Committee 201, and his knowledge of both experimental findings and practical applications has been invaluabletothe committees activities. A

9、total of 24 papers was presented at the four sessions of the symposium. The speakers addressed topics ranging from fundamental laboratory studies of concrete durability to case histories of concrete rehabilitation. This volume has been arranged in three parts. Part I covers the more funda- mental as

10、pects and laboratory investigations. Part II covers field studies where concrete is exposedto naturalconditions. Part III covers case histories of the performance and rehabi- litation of concrete structures in severeserviceenvironments. The symposium was noted for its international flavor and for th

11、e variety of topics addressed. These included, among others, freeze-thaw resistance, deicer scaling, permeability, corrosionofreinforcementandprestressing, sulfateresistance, microbiologically-induced deterioration, and performance in marine environments. The authors are to be congratulated on the c

12、larity of their presentations and their prompt response to the many requests from the symposium chair. I would like to thank Mr. Steven Gebler for serving as co- chairman of this symposium, and Messers David Stark and Bernie Erlin for serving as session chairmen. I would also like to thank the many

18、eived a Bachelors Degree in Civil Engineering in 1938. Subsequent to graduation, Mr. Klieger served as a research assistant intheMechanics Department, as amaterials inspector for the state of Wisconsin, and as an assistant engineer with the U.S. Department of Agriculture. In 1941 he joined the Portl

19、and Cement Association, Chicago, Illinois and, with the exception of military service from 1942 to 1945, was employed by PCA until retiring in 1986. While at the PCA, Mr. Xlieger served in the capacities of associate research engineer, senior research engineer, manager of field research, manager of

20、applied research, and director of concrete materials research. He was responsible for much of the work of PCA on durability of concrete, with special emphasis on frost resistance, resistance to deicing chemicals, and sulfate resistance. Mr. Klieger has received many awards, including the AC1 Disting

21、uished Service Award in 1970, the ASTM Award of Merit in 1970, the ASTM Frank E. Richart Award in 1977, and the AC1 Arthur R. Anderson Award in 1980. Mr. Klieger is a Fellow and Honorary Member of AC1 and also a Fellow and Honorary Member of ASTM. He has served on AC1 and ASTM committees too numerou

Mather SvnoDsis: Concrete will be imune to the effects of freezing and thawing if (1) it is not in an environment where freezing and thawing take place so as to cause freezable water in

34、 the concrete to freeze, (2) when freezing takes place there are no pores in the concrete large enough to hold freezable water (i.e., no capillary cavities), (3) during freezing of freezable water, the pores containing freezable water are never more than 91 percent filled, i.e., not critically satur

35、ated, (4) during freezing of freezable water the pores containing freezable water are more than 91 percent full, the paste has an air-void system with an air-bubble located not more than 0.2 mm (0.008 in.) from anywhere (L I 0.2 mm), sound aggregate, and moderate maturity. Sound aggregate is aggrega

36、te that does not contain significant amounts of accessible capillary pore space that is likely to be critically saturated when freezing occurs. The way to establish that such is the case, is to subject properly air-entrained, properly mature concrete, made with the aggregate in question, to an appro

37、priate laboratory freezing-and-thawing test such as ASTM C 666 Procedure A. Moderate maturity means that the originally mixing water-filled space has been reduced by cement hydration so that the remaining capillary porosity that can hold freezable water is a small enough fractional volume of the pas

38、te so that the expansion of the water on freezing can be accommodated by the air-void system. Such maturity was shown by Klieger in 1956 to have been attained when the compressive strength reaches about 4,000 psi.

INTRODUCTION Most of the concrete that has ever been made in the world was made and used in environmental circumstances in

41、 which the issue of whether or not it would be adversely affected by freezing and thawing was irrelevant since the environmental exposure either did not involve freezing and thawing or it could be assumed with confidence that, when the concrete froze, it would not be critically saturated. It is not

42、necessary to know how to make concrete that will be immune to the effects of freezing and thawing if the concrete that one is interested in making will never be exposed to freezing and thawing when in a critically saturated condition. Concrete that is used in environmental situations in which it is

43、exposed to freezing and thawing while critically saturated and which is unaffected by such exposure has been made for probably as long as concrete has been made. Such inadvertently or unintentionally frost-resistant concrete has been made using aggregates that were frost resistant, with cement paste

44、 that was air entrained, or was concrete that, in spite of becoming critically saturated, had capillary porosity sufficiently low that the 9 percent expansion of the freezable water could be accommodated by the elastic and creep strain capacity of the concrete without rupture. So far as I can tell f

45、rom such literature as I have examined, up qntil about 50 or 60 years ago most people concerned with resistance of concrete to freezing and thawing simply used the rule of trying to figure out what materials and proportions and construction practices had been used previously with success in a compar

46、able exposure and attempted to duplicate or at least simulate those same materials and proportions and practices in the new concrete; without understanding, in any particular detail, why those aggregates, a cement of that composition, and a concrete produced in the way a particular concrete was prod

47、uced, yielded It durable concrete . This symposium honors Paul Klieger. With that in mind, I looked at the index of the first 227 Bulletins of the Research Department of Portland Cement Association Research and Development Laboratories, published in July 1969, and I observed that 18 Bulletins are li

48、sted in the author index following the entry “Klieger, Paul.“ I then looked at the titles and abstracts of I - . each of these, beginning with Bulletin 24 in 1949, which deals with the effect of entrained air on a number of properties of concrete including freezing-and-thawing resistance, all the wa

49、y down to Bulletin 218 in 1967 which deals with laboratory studies of blended cements for their effects on properties of concrete including freezing and thawing. So far as I could tell, 15 of the 18 Bulletins listed were concerned wholly or in part with freezing and thawing. As I shall emphasize later, it was Kliegers 1956 Highway Research Bulletin No. 150 paper that became PCA Research Bulletin 82 (Klieger, 1956) that was called “Curing Requirements for Scale Resistance of Concrete“ that contributed for the first time, at least that I ev
