  • Fineness test, soundness test, consistency test and setting time test
• Concrete


  A composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time
• Fresh Concrete


  • Slump test, VeBe Test, K-slump test
• Hardened Concrete


  • Compression test, Flexural Strength test, and destructive and non-destructive test
• Bitumen


  A black viscous mixture of hydrocarbons obtained naturally or as a residue from petroleum distillation. It is used for road surfacing and roofing.
• Bitumen


  • Determining bitumen content, flash and fire point of bitumen, penetration of bitumen, softening point of bitumen, and specific gravity of bitumen
