The title of the publication is “Compressive strength of reduced concrete specimens considering dimensional distortion of coarse aggregates” and consists in an investigation on the mechanical behavior of small cylindrical specimens in relation to the minimum standard size. Statistical and dimensional analyses were performed for three different compressive strength classes and four grades of coarse aggregates. The following evaluations were performed: a) influence of the dimensional distortion of aggregates on the compressive strength of small concrete specimens; b) analyses through hypothesis testing between strength means; c) the use of prediction coefficients with statistical reliability for correcting the dimensional distortion of aggregates; and d) influence of the wall effect for different specimen sizes and concrete mixes.
