Eco-Efficient Rendering Mortars: Use of Recycled Materials focuses on the use of waste materials into cement-based renders, discussing the origins, treatment processes and properties of relevant wastes. The book dispels mistrust through demonstrating the technical feasibility and environmental benefits of eco-efficient rendering mortars. It considers the characteristics of different waste products, such as aggregates, fillers, binders and additions. The functional requirements of renders are also discussed alongside their impact. Finally, the title considers the lifecycle and durability of modified mortars.  This book offers robust support  and clear guidance on the use of wastes as a substitute for natural aggregates and binders.

Key Features

  • Presents evidence supporting the use of wastes as a substitute for natural aggregates and binders
  • Characterizes wastes and considers how to best incorporate different kinds of waste into renders
  • Gives details on the technical efficiency and environmental impact of different waste materials on mortars
  • Analyzes the impact of wastes on render performance in terms of fresh state, mechanical, water and durability
  • Considers the lifecycle assessment and durability of modified mortars


Construction industry specialists; researchers in sustainable materials and products; researchers, graduate and post-graduate students in civil engineering, architecture, materials science, industrial management and allied fields
