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
Durability and strength are two most important criteria for the design of reinforced concrete structures. These are the two requirements for the long term performance of concrete structures. Any de
A long service life is considered synonymous with durability. Since durability under one set of conditions does not necessarily mean durability under another, it is customary to include a general r
