**Preface to "Research and Development of Modified Building Materials"**

This book represented an effort to gather research works from scholars all over the world dealing with composites. In construction, composites have a key role in the performance and functionality of buildings, and as technology is continuously opening up new horizons, new, innovative and high-tech materials are being derived, covering different needs.

I want to thank all those contributing to the creation of this e-book. It requires devotion and hard work to manage to deliver something to the scientific community. I hope it will be of use to as many as possible.

For me, it was an exciting journey, and I learnt a lot!
