INTRODUCTION

Concrete:

It consists of cement, sand and water with the addition of some kind of

aggregates, such as sand or gravel. The concrete of the most important

materials for construction and infrastructure

ACTIVITY 1: HUNTING FOR OBJECTS MADE OF CONCRETE

Al-Bairaq has been a new experience for us and we are very grateful for it. We learned science in a new way and were challenged to make something unusual

CONCLUSION

For that reason we would like to dedicated special thank you to the sponsors UNESCO, Qatar National Commission, RasGas and Shell.

Many thanks to Al-Bairaq project, Eng. Ruba Ali and my school for supporting us during our journey with a AL-Bairaq
