What is Prestressed concrete ?
Prestressed concrete is also a special type of concrete. As we are aware of the fact that concrete is good in compression and weak in tension. We stress the concrete
Concrete Technology
Concrete is the backbone of modern world. It is of utmost importance for any civil engineer to have a good understanding of the properties of concrete and its design methods.
Effect of admixtures|IS-10262| Concrete mix design calculator
Admixtures are chemical compounds that alter the properties of concrete. We can add admixtures before or during the concrete mix as an ingredient of concrete, other than cement, aggregate, and
M20 Nominal mix|IS-10262| Concrete mix design calculator
Nominal mix and design mix are two different ways which is used for proportionating ingredients of concrete. Selection of type of concrete mix depends on the type of structure, nature
Effect of Exposure condition|IS-10262| Concrete mix design calculator
While designing the concrete mix, you might have noticed the parameter called Exposure condition. This parameter plays a significant role in the design. Hence, it is very important to have
M50 concrete mix|IS-10262:2009 |IS-456:2000 | Concrete mix design calculator
M50 grade of concrete is mostly used for high rise buildings or structures under dynamic loading. It is very important that a civil engineer should know how to design the
Concrete mix design calculator application | M25 grade
M-25 is the most common design mix in routine construction work. Learning this is an essential step for becoming an excellent civil engineer, whether at site or for your degree
What are the different special concrete used for construction?
“Special concrete for special construction projects.” This statement is valid due to its unique property and benefits over usual mix. Special concrete refers to mix that has unique properties that
What is curing of concrete and why it is practiced ?
Curing can be defined as a process of keeping the concrete moist and warm enough so that the hydration of cement can continue. More elaborately, it can be described as
Quality of water to be used in concrete mix for construction
It is very important to check the water quality of the concrete mix. As a slight change in the chemical composition of water may result in a drastic change in
Aggregates crushing value test – Compression testing machine
The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing apply a gradually increasing compressive load. The strength of aggregate is calculated by the
