1.5.1 Properties of hardened concrete

• Factor affecting deformation is when load applied to it.

• Two type of deformation:

– Elastic deformation

As the load increases the deflection increases. When the

load removed the concrete structures such as beams

returns to its original position.

– Creep deformation

If a load is applied to a concrete beam it will initially

undergo elastic deformation. As time progress, it will

continue to deflect even though the load does nnot

change.
