Procedure Aggregate Impact Value (AIV) = B/A x 100 Where B = weight of aggregate passing through 2.36 mm sieve A = weight of the oven – dried sample Note AIV should not be more than 45% for use in concrete other than wearing surfaces, and 30% for concrete used for wearing surfaces such as…
Procedure Aggregate crushing value (ACV) = B/A x 100 Where B = weight of aggregate passing through 2.36 mm sieve A = weight of the surface dry sample taken in mould Note ACV should not be more than 45% for use in concrete other than wearing surfaces, and 30% for concrete used for wearing surfaces…
Aggregates are most commonly used engineering material in construction and have many applications as they have several desirable characteristics. Aggregates are the granular materials that are mixed with cement and water to form concrete. They occupy generally 60 to 75% of the concrete volume and 70 to 85% by mass. Aggregates can be natural such…
Aggregates are one of the main components of concrete, along with cement and water. They are granular materials that occupy most of the volume of concrete and provide strength and stability to the mixture. Aggregates can be natural, such as sand, gravel, and crushed stone, or artificial, such as slag, fly ash, and recycled concrete….
If you are in the field of construction or in the engineering industry you must have frequently heard the term aggregates. Aggregates play an important role in building materials as they are responsible for ensuring the strength and durability of the structures. In this blog, we will discuss the definition of aggregates, classification of aggregates…
Cement is an important building material which has broad applications in several fields. Cement has many uses and applications depending upon its type and composition. Most common uses of cement are listed below which are used in a variety of ways in construction and other industries. Cement Uses in Construction and Civil Engineering Cement mortar…
