Every concrete design follows a specific amount of water quantity. But there are some important sources of water other than the designed that can contribute to an increase in water content of the c

The main difference between lean and PCC concrete is that lean concrete contains less cement compared to the water content present in it. This means, when compared to plain cement concrete (PCC), t

Flexible or bendable concrete gains ductility property while normal concrete shows the brittle property. This difference of flexible concrete from normal concrete makes it available for large appli

Soundness of cement can be defined as its ability to retain its volume after it gets hardened. This means that a properly sound cement will undergo minimum volume change after it converts into the

Modulus of elasticity of concrete is defined as the ratio of stress applied on the concrete to the respective strain caused. The accurate value of modulus of elasticity of concrete can be determine

Ready mix concrete is generally produced in large quantity and is transported to distant places for placement in structural elements. Sometimes the distance can be in many kilometers or miles. So,

Fly ash is used in concrete as an admixture as well as in cement. The effect of these fly ash on durability of concrete is discussed in this article.

Air entrainment affects compressive strength of concrete and its workability. It increases the workability of concrete without much increase in water-cement ratio. Compressive strength of concrete

Purpose of high performance lightweight concrete utilization is to reduce cost or enhance functionality of the structure or the combination thereof. The economy of high performance lightweight conc

Any concrete structure would eventually see cracks and demand proper repair. Nonetheless, one needs to understand the nature of the crack to repair them properly. Generally, cracks are either stati
