Concrete Roads: PQC, Methods of Construction and How it is Made

Concrete Roads: PQC, Methods of Construction and How it is Made! Introduction to Concrete Roads: Concrete roads fall under the category of high quality/superior type of roads built with cement concrete. These pavements may or may not be provided with sub-base/base courses, and they may be constructed directly over a well-compacted soil subgrade. They derive their strength to support the [...]

How to Determine Loads while Designing a Steel Structure ? | Construction

Determination of the loads for which a structure has to be proportioned is an important task in a design. The various loads that are likely to act on a structure and the possible combinations of such loads that can act are all points to be considered. Dead load refers to the weight of a structure. It is necessary to estimate [...]
