The aggregates used in different construction works such as roads, buildings, pavement etc. So many different kinds of tests are applied on coarse aggregates such as the impact values test, crushing value test, specific gravity test, and sieve analysis test to know its strength.  What is an abrasion test? The…

The primary purpose of using coarse aggregates is to enhance the strength of the concrete. Moreover, the coarse aggregates will easily blend with other concrete ingredients and make it as a homogeneous element. The impact value test has been conducted on aggregate to determine its bearing capacity against sudden impact. …

Choosing the right size and grade of aggregates impact the overall strength of concrete. The aggregates are taken out from the natural resources and classified into different grades. Grading of aggregates helps to identify the right aggregates for any construction works. Advantages of Aggregates Available in many locations Low cost…

Many innovations are evolving in the construction industry to enhance the strength and durability of the structure.  Concrete, A major construction material that is strong in compression and weak in tensile load. So the steel reinforcement has been embedded to stabilize the concrete against the tensile force.  Though the reinforced…

The concrete that made by mixing different aggregate materials at specific ratios has different chemical particles. Various properties of concrete make it very strong and durable.  The quality of material, improper workmanship indirectly affects these properties and reduces the lifespan of the concrete. The concrete also loses its strength and…

The bitumen and tar are used as a binding agent. It is mixed with the aggregates in construction of roads. They are easily blendable when the aggregates are in dry condition. In case of water presence in bitumen mixture, it will affect the bitumen bonding with the aggregates and shall…

The bitumen is a by-product material of petroleum. It is mainly used in construction activities.  It is used primarily in highway construction. Throughout the lifetime of the road, it exposes to hot climatic conditions and heavy traffic load. To ensure quality and strength, bitumen is subjected to various tests. The…

The quality and strength of bitumen have been determined by the penetration test, flash and fire point test, and softening point test. Now the bitumen extraction test is conducted to find the quantity of bitumen used in bituminous concrete in percentage. What is a Bitumen Extraction Test? The test used…

Bitumen is a by-product of crude oil which has strong adhesive and waterproofing properties. It is involved in many tests to determine its grade and durability.  The penetration test is performed to determine the penetrate value of the bitumen and a softening point test is conducted to determine the viscosity…

The crushed sand is artificial sand which is manufactured by crushing granite stone. It is manufactured artificially, so it is also called M sand or manufactured sand. Difference between crushed sand and river sand Parameters Crushed Sand River Sand Cost The crushed sand is manufactured from available rock stone, and…
