Done by: TBZ_Rocks7 Group School Name: Tariq Bin Ziyad Independent Secondary School for Boys Concrete: This module enables the students to study concrete properties in general through experiments done by the students. Aim of the research is to provide an idea of the possible help in the construction of buildings is different from the traditional system. Our idea of the project is to add a type of polymer to the concrete, and this type is liquid rubber.

- 1. I am Discovering Materials Concrete ( ROCKS ) Ibrahim ali almansouri Ahmed EL Shebany
- 2. Outlines: Introduction Activities Project Design Conclusion
- 3. Introduction
- 6. Activities
- 7. Activity 1: Hunting for objects made of concrete
- 9. Sydney Opera House : Concrete and steel
- 10. Khalifa Tower :
- 11. Conclusion We discovered that there are old buildings built by cement and concrete, despite it being different from the concrete used these days .
- 12. Activity 2: Comparing different kinds of cement
- 13. Sample Portland Cement Water Additives Salt ( CaCl2 ) Table sugar A 200 g 100 ml 0 0 B 200 g 100 ml 0 2 g C 200 g 100 ml 12 g 0 Cement A Cement B + Sugar Cement C + Salt Compare between 3 kinds of cement :
- 14. Steps :
- 15. Time min Temp A Temp B +sugar Temp C +salt Mass A Mass B +sugar Mass C +salt 3 21.4 22.5 28.5 281g 1:25 Pm 243g 285 g 1:25 pm 261g 216g 1:25 Pm 212g 6 21.4 22.6 30.2 9 21.4 22.6 31.5 12 21.4 22.7 32.6 15 21.5 22.7 32.6 18 21.5 22.8 32.7 21 21.6 22.5 32.4 24 22.3 22.3 32.1 27 22.7 22.3 31.4 30 23.1 21.7 30.8 NEXT DAY Measurements of the temperature of each of the samples :
- 16. Conclusion We discovered that the salt speeds up the hardening of concrete unlike sugar which slows the hardening down .
- 17. Activity 3: Comparing Different Concrete Formulations Part A Part B
- 18. Part A DENSITY= MASS/VOLUME 1 2 3
- 19. MASS VOLUME DENSITY NOTES SAND 100 g 60 ml 1.6 g/ml Low volume HIGH density GRAVEL 100 g 72 ml 1.38 g/ml MIX 100 g 56 ml 1.78 g/ml Part A

- 21. Steps : Part B
- 22. Conclusion We discovered in this activity that if volume is decreased the density will be increased and this what we need to make a good concretes .
- 23. Activity 4: Testing Properties of Concrete

- 25. Conclusion We discovered in this activity that reinforced concrete be more solid .
- 27. Introduction and Rationale : The reason for our interest in this project is the idea that excite our admiration and impress a lot of young people, particularly in help them build their future, this project is a process of building up to its name .
- 28. project idea Our idea of the project is to add a type of polymer to the concrete , and this type is liquid rubber .
- 29. Comparison Increase the strength of the link between the elements of concrete . Increase the frictional resistance . Increased resistance to bending and tensile strength of concrete . High absorption of sound .
- 31. Our project :
- 32. Results Rubber and cement Prevents cracks Thermal insulator Sound insulator 30%
- 33. Conclusion Recommendations We conclude our project by adding some information about the rubber material, that whenever you increase this article will increase the rate of breakage to the strongest rate of 40% . We recommend that this project is used in places that are exposed to the sun and also can be used in the halls of higher noise such as weddings halls or laboratories .
- 34. Many thanks to my teachers, school and Eng. Doaa from Albairaq team from Center for Advanced Materials (CAM), Qatar University for supporting us during our journey with a Albairaq. Also, I would like to thank the sponsors UNESCO, Ras Gas, Shell and Qatar Petroleum.
