Creep in Concrete, Factors affecting Creep & Effects of ...

A poorer paste structure undergoes higher creep. Therefore, it can be said that creep increases with increase in water/cement ratio. In other words, it can also be said that creep is inversely proportional to the strength of concrete. Broadly speaking, all other factors which are affecting the water/cement ratio are also affecting the creep. 3.

What is the Difference Between Concrete and Cement?

The primary difference between concrete and cement is that concrete is a composite material made of water, aggregate, and cement. Cement is a very fine powder made of limestone and other minerals, which absorbs water and acts as a binder to hold the concrete together.While cement is a construction material in its own right, concrete cannot be made without cement.
