LONG-TIME STUDY OF CEMENT PERFORMANCE IN CONCRETE (CHAPTERS 1 - 4)

THE HISTORY AND SCOPE OF THE STUDY ARE DISCUSSED AND SEL- ECTION OF THE CEMENTS. THE ADVISORY COMMITTEE CONSISTED OF 14 ENGINEERS OF OUTSTANDING ACCOMPLISHMENT; 7 REPRESENTING CONSUMERS OF CEMENT, AND 7 FROM THE CEMENT INDUSTRY. THE BASIS OF SELECTION OF THE 27 CEMENTS REPRESENTING ALL 5 TYPES OF CEMENT IS GIVEN. THE CONSTRUCTION PROJECTS INCLUDED EXPOSURES TO A WIDE VARIETY OF WEATHERING CONDITIONS: 3 PAVEMENTS IN WIDELY DIFFERENT AREAS; CONCRETE PILING IN FRESH WATER AND SEA WATER; PRISMS IN SULFATE SOILS; THIN SECTION EXPOSURE IN SEVERE FREEZING AND THAWING CLIMATES; AND 2 EXPERIMENTAL 'FARMS'INVOLVING BOX, SLAB AND COLUMN SPECIMENS. THE VARIOUS DETAILS ARE DESCRIBED OF THE MANUFACTURE OF THE CEMENTS. THE RESULTS ARE PRESENTED OF A WIDE VARIETY OF LABORATORY TESTS OF THE 27 CEMENTS USED IN THE INVESTIGATION AND OF THE CLINKERS FROM WHICH THEY ARE MANUFACTURED. THE PETROGRAPHIC STUDIES ARE PRESENTED WHICH WERE MADE ON THE 21 LOTS OF CLINKER MANUFACTURED FOR THE 27 LONG-TIME STUDY CEMENTS, INCLUDING QUANTITATIVE MINERAL ANALYSES. THE MINERAL COMPOSITION OF THE CEMENTS ARE PRESENTED IN TABULAR FORM. THE PAPER ALSO IS CONCERNED WITH THE HISTORY AND TECHNIQUES OF CLINKER MINERAL IDENTIFICATION AND WITH CORRELATIONS BETWEEN THE MINERAL COMPOSITIONS AND VARIOUS OTHER FEATURES OR PROPERTIES OF THE CLINKERS AND THE CEMENTS. /PCA/
