Alkali Activated Binders Based Concrete Specimens: Length Change and Fracture Tests.
Original language description
The aim of this paper is to quantify mechanical fracture and length change parameters of the two types of concrete with alkali activated binder. They both contained blast furnace slag (BFS), which was substituted by low calcium fly ash (FA) in amount 50% in the first case and by by-pass cement kiln dust (CKD) in amount 25% in the second case.The six beam specimens (75 x 75 x 295 mm) were made from each mixture. After demolding specimens were placed in air storage for 28 days. During this period length change (shrinkage) were recorded in accordance with ASTM C490 (2011). After that the three-point bending test was performed on these specimens with initial stress concentrator at the age of 28 days to obtain the mechanical fracture parameters. Records of fracture tests in form load versus deflection (F–d) diagrams were evaluated using effective crack model and work of fracture method.
