FRACTURE BEHAVIOUR OF ALKALI ACTIVATED CONCRETE MEASUREDFROM THREE-POINT BENDING TEST WITH CHEVRON NOTCH
Original language description
Specimens for the bending tests with the chevron notch are suitablefor the evaluation of the fracture energy/toughness of civil engineering materialslike concrete. The main advantage of this test set-up is that no sharp pre-crack has to be introduced, because a sharp crack is formed during loading at the beginning of the test. Furthermore, no crack length measurement is required, and a stable crack growth can be reached due to chevron geometry of the notch. In this contribution a difference of the ligament area of the specimens with the straight through notch and the chevron notch was investigated.The experimental campaign was performed on the alkali activated concrete three-point bending specimens testedwith straight through notch andwith the chevron notch. The specimens had the same ligament area in order to quantify the influence of the chevron notch boundary conditions on the value of the work of fractureand the fracture energy.
