Influence of Coarse Aggregate Maximum Size and Core Diameter on the Compressive Strength of Concrete Cores: A Factorial Experimental and Statistical Study
Description
This dataset supports the study "Influence of Coarse Aggregate Maximum Size and Core Diameter on the Compressive Strength of Concrete Cores: A Factorial Experimental and Statistical Study." It contains the summary experimental and statistical data from a three-factor factorial campaign (mixture/coarse aggregate maximum size × core diameter × curing age) evaluating the compressive strength of concrete cores drilled from three mixtures of equal design strength (f'c = 42 MPa) but different nominal maximum aggregate size (1/2, 3/4 and 1 in), with cores of five diameters (1, 1.5, 2, 2.5 and 3.7 in) tested at 28, 42 and 56 days alongside standard reference cylinders. The workbook contains eight sheets: (1) physical and mechanical properties of the fine and coarse aggregates and cement; (2) mix proportions for the three concrete designs; (3) extracted core diameters and their compliance with the 2×Dmax minimum-diameter requirement; (4)–(5) full and reduced multifactorial ANOVA tables for core compressive strength expressed as a percentage of the design strength; (6)–(7) Fisher LSD (95%) homogeneous-group tables by core diameter and by curing age; and (8) the core and cylinder strength matrix by diameter, age and mixture underlying the study's summary results figure. A README sheet describes each table and its units.
