INFLUENCE OF THE SHAPE OF THE SAMPLE ON THE COMPRESSIVE STRENGTH IN CONCRETE /IN GERMAN/

FOR MECHANICAL AND GEOMETRIC REASONS, COMPRESSIVE STRENGTH DEPENDS ON THE HEIGHT OF THE SAMPLE AND THE SHAPE OF ITS CROSS-SECTION. THE COMPRESSIVE STRENGTH OF A CONCRETE SPECIMEN IN THE SHAPE OF A RELATIVELY LARGE PANEL IS EQUAL TO ONLY A QUARTER OF THE COMPRESSIVE STRENTH OF A CUBE. ACCORDING TO CURRENT SPECIFICATIONS THE TRUE ULTIMATE STRENGTH OF CONCRETE SAMPLES DEPENDS, FOR THE GREATEST PART, ON THE SHAPE OF THEIR CROSS-SECTIONS. USING MOLECULAR FORCES IT IS POSSIBLE, AT THE PRESENT TIME, TO ESTABLISH A QUALITATIVE RELATION ONLY BETWEEN SHEARING AND COMPRESSIVE STRENGTH ON THE ONE HAND, AND THE ABSOLUTE DIMENSIONS OF THE SAMPLE ON THE OTHER. /A/LCPC/RRL/
