This book explores recycling and reusing construction wastes as alternative coarse aggregates and presents this as a possible solution for the major challenge of making sustainable concrete. It explores the reduction of cement use and the overcoming of some inferiorities in recycled coarse aggregate through the partial substitution of cement with supplementary cementitious materials (SCMs). The book evaluates the effect of low-volume SCMs (mainly fly ash) in 100% recycled coarse aggregate based concrete and comprehensively investigates this sustainable concrete for strength, safety,...

Cementitious materials, rocks and fibre-reinforced composites commonly termed as quasibrittle, need a different fracture mechanics approach to model the crack propagation study because of the presence of significant size of fracture process zone ahead of the crack-tip. Recent studies show that concrete structures manifest three important stages in fracture process: crack initiation, stable crack propagation and unstable fracture or failure. Fracture Mechanics concept can better explain the above various stages including the concepts of ductility, size-effect, strain softening and...
