Original Abstract

Mechanical fracture parameters obtained from three-point bending tests on concrete specimens with a central edge notch are presented in this paper within the project of the Grant Agency of the Czech Republic "Assessment and Prediction of the Concrete Cover Layers Durability". A total of four sets of specimens were tested. The concrete used in each set differed in cement dosage, which ranged from 250 to 455 kg per m3 of fresh concrete. Three specimens in each set were tested at the age of 28 days. Increasing the dosage of cement influences the mechanical fracture properties of concretes in both positive and negative ways.
