How to do post-tensioning? Is this method is applicable for all RCC elements. Please, anyone, explain me.

Post-tensioning is a form of prestressing. Prestressing simply means that the steel is stressed (pulled or tensioned) before the concrete has to support the service loads. Most precast, prestressed concrete is actually pre-tensioned-the steel is pulled before the concrete is poured. Post-tensioned concrete means that the concrete is poured and then the tension is applied but it is still stressed before the loads are applied so it is still prestressed.
