Testing of concrete and quality control: Variability of concrete strength and acceptance criteria and Non – destructive tests
1.1 Various strength of concrete 1. Tensile strength: Tensile strength (Fct) = 0.35 (Fck)1/2 Where, Fck = Characteristics compressive strength 2. Compressive strength: 3. Shear strength: 4. Bond strength: 1.2 Compressive, tensile and bond strength tests Compressive strength tests: 1. Cube test: Compressive strength of concrete = Force at failure / Area 2. Cylinder test: … Read more
