Influence of cement contents on the fracture parameters of Roller compacted concrete pavement (RCCP)
This experimental research explored how the cement content (or the cement-to-aggregate ratio) impacted the fracture parameters and ductility of Roller compacted concrete pavement (RCCP). For that end, three-point bending tests were carried out on notched beams with several cement-to-aggregate ratios (from 12 to 17%). For all the mixtures, three approaches, including the work of fracture method (WFM), size effect method (SEM), and boundary effect method (BEM), were employed to assess the parameters of fracture. On this regard, as cement-to-aggregate ratio increased from 12 to 17%; (i) initial fracture energy and total fracture energy increased slightly in all three methods; (ii) the fracture toughness increased slightly in both SEM and BEM; and (iii) with respect to the size effect curve, the performance of RCCP specimens approached linear elastic fracture mechanics criteria.
