Shrinkage of Concrete Presently we shall discuss the volume change on account of inherent properties of concrete “shrinkage”. One of

The hydration of cement is not a momentary action but a process continuing for a long time. Of course, the

In this post, I am going to discuss some effects of superplasticizers on the workability of fresh concrete. Superplasticizer is

Fire Resistance of Concrete-Durability of Concrete In this post, we are going to describe the fire resistance of concrete. Fire-resistance

Segregation means separation of designed fresh concrete ingredients from each other resulting in the non-uniform mix. More specifically, this implies

The main reason why concrete cracks is because it shrinks. It shrinks as it loses water. Most of that happens

Types of Durability There are many types but the major ones are: Physical durability of concrete Chemical durability of concrete

The ability of concrete to withstand the conditions for which it is designed without deterioration for a long period of

Compressive strength of concrete in INDIAN STANDARDS is denoted by fck(characteristic compressive strength).The METHODS OF TESTS FOR STRENGTH OF CONCRETE is given in IS:516–1959. The compressive strength of

Advantages and disadvantages of prestressed concrete can be listed as follows Advantages of Prestressed Concrete: Prestressed concrete members are free

You already know that compaction is an important process after placing of concrete. Here I am going to write about

Lean Concrete The main difference between lean and PCC Concrete is, In lean concrete, the cement content is less compared

Transportation of concrete is an important activity in the production of concrete. The time taken in transit should be a

What is water cement ratio? The ratio between the weight of water to the weight of cement in the concrete

  Concrete is strong in compression because the granite aggregates are very strong in compression . If the concrete is
