Fresh concrete has different properties which are required for construction of concrete structures at site. The most important properties of fresh concrete are discussed. Properties of Fresh Concrete for Construction Works Workability of Concrete Concrete workability is the relative ease ...
CONCRETE CREEP
CONCRETE CREEP Creep is defined as the long term deformation under a sustained load. Water within the hardened cement paste is forced to more as a result of the applied load. This movement of moisture is the primary cause of ...
Stress-Strain Curve for Concrete
Stress strain curve of concrete is a graphical representation of concrete behavior under load. It is produced by plotting concrete compress strain at various interval of concrete compressive loading (stress). Concrete is mostly used in compression that is why its ...
