4. Main Prop. OF Fresh Concrete

8. 3 Ways to determine Consistency of Fresh Concrete

19. Slump Test >Table : Workability, Slump and Compacting Factor of concrete with 19 or 38 mm (3/4 or 1 1 / 2 in) maximum size of aggregate. Degree of workability Slump (mm) Compacting Factor Use for which concrete is suitable Very low 0 - 25 0.78 Very dry mixes; used in road making. Roads vibrated by power operated machines Low 25 - 50 0.85 Low workability mixes; used for foundations with light reinforcement. Roads vibrated by hand operated Machines Medium 50 - 100 0.92 Medium workability mixes; manually compacted flat slabs using crushed aggregates. Normal reinforced concrete manually compacted and heavily reinforced sections with vibrations High 100 - 175 0.95 High workability concrete; for sections with congested reinforcement. Not normally suitable for vibration

20. Slump Test >Table : Relation between Consistency and Slump values Slump (mm) 0 - 20 20 - 40 40 - 120 120 - 200 200 - 220 Consistency Dry Stiff Plastic Wet Sloppy

26. Flow Test

27. Flow Test Percent of Flow 0 – 20 % 20 – 60 % 60 – 100 % 100 – 120 % 120 – 150 % Consistency Dry Stiff Plastic Wet Sloppy

29. Ball Penetration Test (Kelly Ball)

32. What Difference Between … ?

44. Compacting Factor Test Workability Slump (mm) C.F Uses Very Low 0 - 25 0.78 Roads - Pavements Low 25 - 50 0.85 Foundations Concrete Medium 25 - 100 0.92 Reinforced Concrete High 100 - 175 0.95 Reinforced Concrete (High Reinforcement)
