Preface

As the world moves further into urbanization, there is a greater need for construction

As natural resources become scarce, the use of recycled materials for construction purposes has become increasingly common. Over the past decade, there has been a significant increase in the utilization of recycled materials in the construction industry. Natural resource depletion, the increasing cost of quarrying, and materials transportation have caused an increase in the cost of natural materials. Therefore, if the use of recycled materials in the construction industry can be justified, it will result in substantial advantages in structure and infrastructure construction coupled with a reduction in the construction cost as well as an improvement in sustainability.

The use of recycled materials in civil projects is not a recent development. In fact, the utilization of recycled materials in construction has a long history. However, finding innovative uses for recycled materials is one of the current priorities in the

The aim of compiling this book has been to familiarise the reader with some innovative and alternative construction materials used in civil engineering. The book includes information on using hybrid aggregates, recycled sand, and bio-
