Abstract

Extensive research has demonstrated that AAC exhibits similar mechanical strength to OPC and even performs better in many aspects such as early strength development, high resistance to chemical attack and low hydration heat and good resistance to freeze-thaw cycles. However, similar to that of OPC, the AAC still has a brittle nature. Therefore, an in-depth understanding of its fracture properties is a prerequisite for the safe application of AAC in practical structural applications. This research aims to investigate the fracture energy and tension softening characteristics of AAC concrete as compared to its OPC counterpart through three-point bending tests on notched concrete beams. The effects of mix proportion of AAC concrete on its fracture properties are also investigated.
