| Video Discription | CONCRETE GRADE USED IN BURJ KHALIFA https://www.youtube.com/watch?v=K1nmNjYCqkM This video simply explain the relationship between cylinder strength and cube strength. And also explain some misunderstanding about the notation of concrete grade. Subscribe here https://bit.ly/3m5eRuK #concretegrade #concrete #cylinderstrength #cubestrength What does C32 /40 mean? C32/40 concrete means a concrete having 28 days crushing strength of 32 MPa when cast as a cylinder of 150 mm diameter and 300 mm height, and 28 days crushing strength of 40 MPa when cast as a cube of 150 mm sides. The formula to convert cube strength to cylinder strength is: Cylinder strength = Cube strength X 0.8 Why cube strength is more than cylinder? Compared with the cube test the , the advantages of the cylinder are less end restraint and a more uniform distribution of stress over the cross section , for these reasons the cylinder strength is probably closer to the true uniaxial compressive strength of concrete than the cube strength. What is FCK and FCU? in the plastic theory, the equivalent 'yield stress' of concrete in compression is assumed in Eurocodes 2 and 4 to be 0.85 fck, where fck is the characteristic cylinder strength of the concrete. ... In the UK, the compressive strength of concrete is specified as a cube strength, fcu. What do you mean by compressive strength? : the maximum compressive stress that under gradually applied load a given solid material will sustain without fracture What is the loading rate used in compressive strength test? 140 kg/cm2 per minute The compression testing machine is used for testing the compressive strength of concrete. What is the rate of loading on compression testing machine? Load should be applied gradually at the rate of 140 kg/cm2 per minute till the Specimens fails. Where is compressive strength used? Some materials fracture at their compressive strength limit; others deform irreversibly. Compressive strength is a key value for designing structures. The compressive strength of concrete is the most common performance measurement used by engineers when designing buildings and other structures. How do you calculate compressive strength? The compressive strength was calculated by using the equation F= P/A, where F is compressive strength of specimen in Mega Pascal, P is the maximum applied load by newton and A is the cross-sectional area estimated in mm 2 . _sX9IS3Tftk |
