Specific Gravity is defined as the ratio between the volume of any given material to the volume of the same quantity of water. The value ranges from 0.1-100 for any given material. In simple, It is used to index the floating ability of materials. If the value ranges below <1,…

The cement reacts with water and turns into a paste to form a layer on other ingredients to make the (concrete) bond stronger.  The optimum quantity of water and cement produces a strong, homogeneous mix material that gives consistency to the concrete or mortar.  What is the consistency test of…

Cement acts as a binding agent in concrete, which blends with other materials quickly and makes the concrete as a strong homogeneous element.  The durability of the concrete depends on the properties of cement. The setting time of cement is one of the essential properties of cement.  What is meant…

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…

What is the Charpy impact test used for? The Charpy impact test used to determine the resistance capacity of metal (steel) specimen against sudden impact load of a pendulum which swung from a certain height. The other name of the Charpy impact test is the Charpy V-notch test because of…

Yes!… The steel contains high tensile strength, and that’s why it is prefered in concrete. However, not every steel provides the same yield strength. It differs based on its constituents. Constituent Fe 415 Fe 415D Fe 500 Fe 500D Fe 550 Fe 550D Fe 600 Carbon 0.3 0.25 0.3 0.25…

A structure built by different kinds of construction material consists of various chemical constituents.  As per IS Code, many tests would be conducted to define the quality and strength of the material involved in the construction process.  The construction material must sustain the following conditions to make the structure durable.…

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. …

We know there are two concrete strength testing methods, such as destructive test method and Non-destructive method. We use both methods to check the compressive strength and characteristic strength of concrete. But both test methods can be applied to concrete cubes only after 28 days because the concrete requires proper…

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…
