Presentation on construction process and Classification of slab

This presentation was given by the students of Ahsanullah University of Science And Technology. This presentation was prepared for Details Of Construction Course and it includes classification of slab,construction process of different types of slab

4. What is Slab? A slab is a broad, flat plate, horizontal with top and bottom surfaces parallel or nearly so. It may be directly supported on beams or columns or indirectly on column by using deep panel and column capital.

5. Types of Slab Slab On Beam Flat Slab Flat Plate Slab Waffle Slab

6. Construction Process of Slab On Beam

7. Shuttering/Formwork To form a desired shape of beam and slab Need to carry the weight of RCC of slab and beam until hardening of concrete

8. To resist falling of water from concrete until hardening 2. Providing Steel Sheets

9. 3. Maintaining Clear Cover C.C blocks is used to maintain clear cover Clear Cover is needed to protect the reinforcement from corrosion

10. 4. Reinforcement Placing The reinforcement are knotted with one another using GI(Galvanized Iron) wire The reinforcement are placed in two direction

11. 5. Concrete Casting Casting was done monolithically where the casting of beam and slab are done together To reduce segregation, concrete was dropped from low height

12. 6. Compaction The compaction is done by a vibrator to remove air voids and to make sure concrete has spread uniformly in all direction.

13. 7. Levelling To Provide a smooth surface Levelling was done by using a thick wooden plate

14. 8. Curing The slab was ponded by water for 28 days To complete hydration reaction in order to gain strength of concrete

15. Construction Process of Flat Plate Slab

16. 1. Shuttering/Formwork To form a desired shape of slab Need to carry the weight of RCC of slab until hardening of concrete

17. 2. Maintaining Clear Cover C.C blocks is used to maintain clear cover Clear Cover is needed to protect the reinforcement from corrosion

18. 3. Reinforcement Placing The reinforcement are knotted with one another using GI(Galvanized Iron) wire The reinforcement are placed in two direction
