PLASTIC CONCRETE

THE LIMITATIONS OF THE TRADITIONAL CONCEPT OF PLASTIC CONCRETE ARE BRIEFLY OUTLINED AND CONTEMPORARY MODIFICATIONS ARE REVIEWED. CONSISTENCE IS A MORE APPROPRIATE TERM THAN WORKABILITY WHEN REFERENCE IS INTENDED TO THE PHYSICAL PROPERTIES OF PLASTIC CONCRETE IN RELATION TO CONCRETE PLACING. THREE INDEX PROPERTIES, NAMELY COMPACTABILITY, SPREADABILITY AND STABILITY, ARE CONSIDERED TO BE SUFFICIENT TO SPECIFY CONSISTENCE, AND IN DESIGNING CONCRETE MIXES THESE PROPERTIES SHOULD BE CONSIDERED, SINCE THEY DESCRIBE QUITE DIFFERENT ASPECTS OF CONSISTENCE. PLASTIC CONCRETE MAY WITH ADVANTAGE BE ANALYZED AS A TWO-PHASE MATERIAL CONSISTING OF AN AGGREGATE PHASE WHICH IS DISPERSED IN THE MORTAR PHASE, AND STUDIES OF SOME ENGINEERING PROPERTIES INDICATE THAT THE MORTAR PHASE PLAYS A MAJOR ROLE IN ITS BEHAVIOR. /AUTHOR/
