ANALYSIS OF THE INFLUENCE OF WATER CONTENT ON CONSISTENCY

AN ANALYSIS IS PRESENTED OF THE CHANGE IN CONSISTENCY THAT IS CAUSED SOLELY BY A CHANGE IN THE WATER CONTENT. A NUMERICAL METHOD--THE SO-CALLED K-PROCEDURE--IS DISCUSSED IN DETAIL. IT IS A SIMPLE TOOL FOR THE CALCULATION OF A NEEDED ADJUSTMENT IN THE WATER CONTENT OF CEMENT PASTE, MORTAR, OR CONCRETE. THE K-PROCEDURE IS BASED ON THE ASSUMPTION OF INDEPENDENCE. PREDICTING FORMULAS ARE OFFERED FOR VARIOUS METHODS OF MEASURING CONSISTENCY, AND A MECHANISM IS PRESENTED FOR THE ROLE OF WATER IN FRESH MIXTURES. THIS MECHANISM EXPLAINS WHY AN INCREASE IN THE WATER CONTENT CAUSES A GREATER THAN LINEAR INCREASE IN THE MOBILITY OF A FRESH MIXTURE. NUMERICAL EXAMPLES ILLUSTRATE THE USE OF THE K-PROCEDURE. TO ASSIST WITH PRACTICAL APPLICATION, TABULATED DATA AND NOMOGRAMS ARE PROVIDED FOR THE K-FACTORS OF SEVERAL STANDARD TEST METHODS. /AUTHOR/
