FOR CONCRETE • A typical stress-strain curve for concrete, when tested in a compression-testing machine, is shown in Fig. 3.1. • The stress and strain are approximately proportional to each other up to about half of the ultimate strength. • At higher stresses, the behavior is considerably inelastic.
Air-entrained concrete is typically specified in areas of the country where frost-related damage can occur. The measurement of air content in fresh concrete of normal density is typically performed using the pressure method ().Another useful test is ASTM C 173.However, the pressure method is frequently preferred because it is relatively fast.
Fresh concrete sampling and testing. Different types of concrete testing can be conducted depending on whether the concrete is freshly mixed or hardened. When sampled correctly, fresh concrete provides the most accurate representation of the cube's strength, consistency, density, air content and temperature.
