Why Concrete is Superior to Other Construction Materials? (Part-2)

Dear reader in last part we have learnt about water resistance of concrete; here we will learn about flowability and availability of concrete.


Concrete member can easily be formed into any expected shape and as well as advantage of providing formability makes it universal material, as no other material have shown such characteristics.


This advantage is achieved from plastic consistency at early age. The early age means before it becomes stiffening. The terms stiffing, solidification and hardening will be discussed in upcoming posts. 

Trapezoidal formwork section and finished concrete
For this post, just keep in mind that stiffening means losing consistency of fresh concrete. After this stage the concrete can also be reshaped with revibration; retempering are required which is the act of professionals.


This property allows concrete to flow into formwork that are fabricated according to designed shape. The formwork, after concrete gaining sufficient strength, is removed and reused in another project or further extension of structure.
Exceptional formability of concrete
Regarding availability and cost involvement in concrete construction, it can be included that concrete is readily available and cheapest material for the job. The main components that makes concrete are aggregate, Portland cement and water. All these components are relatively inexpensive.


The components that comprise concrete are generally available all over the world. The consideration which makes concrete superior than steels as an construction materials are :

a. Maintenance

b. Fire resistance

c. Resistance against cyclic loading.
