DEFORMATION OF CONCRETE AND ITS CONSTITUENT MATERIALS IN UNIAXIAL TENSION

STRESS--STRAIN CURVES FOR CONCRETE LOADED IN UNIAXIAL TENSION ARE SHOWN FOR A WIDE VARIETY OF MIXES. THE DATA ILLUSTRATE THE INFLUENCE OF WATER--CEMENT RATIO AND MAXIMUM SIZE, GRADING, AND TYPE OF AGGREGATE ON THE FORM OF THE STRESS--STRAIN CURVE. IN ADDITION, ALL MIXES ARE FOUND TO CONFORM TO A DIMENSIONLESS STRESS--STRAIN CURVE PLOTTED IN TERMS OF TENSILE STRENGTH AND FAILURE STRAIN. STRESS--STRAIN CURVES FOR CEMENT PASTE AND ROCK ARE ALSO SHOWN, AND VALUES FOR THE BOND STRENGTH OF VARIOUS PASTE--ROCK COMBINATIONS ARE INCLUDED. EXPERIMENTAL VALUES OF THE INITIAL TANGENT MODULUS OF DIFFERENT CONCRETES ARE COMPARED WITH ANALYTICAL VALUES OBTAINED BY USING EQUATIONS PROPOSED IN THE LITERATURE, AND FAIRLY GOOD AGREEMENT IS OBSERVED. /AUTHOR/
