Influences of the volume fraction and the type of aggregate on shrinkage in mortars and concretes made with an expansive cement were examined by using 10 cm x 10 cm x 30 cm prismatic specimens. It was found that the measured shrinkage strains of river sand mortars and crushed stone concretes were no
The material under investigation was ordinary concrete of B 20 class, different in the sizes of coarse aggregate and water-cement ratio of the same value w/c = 0.55. It was found during the tests that there were two kinds of sample cracking mechanisms. Some samples cracked at the moment of the initi
Analytical modeling and experimental testing are used to evaluate the fracture toughness of plain concrete. The analytical modeling of the fracture toughness considers both the opening of the crack due to the applied external loads and the closing of the crack due to the interlock pressure of the ag
