Penetration resistance test is a concrete non-destructive test. This test determines the strength of concrete by penetrating a steel rod.Non-destructive test (NDT) and destructive tests (DT) are the the tests done one hardened concrete. Concrete is the oldest and most important construction material in the world.… Read More Penetration Resistance Test – Significance and Procedure
Specific gravity and water absorption test are significant tests on aggregates. Perhaps aggregates are the fundamental and essential components of concrete and play a significant role in the design mix of concrete. More than 70 to 80 per cent of the volume of concrete is aggregate. Hence the water absorption and specific gravity test are essential and significant tests .… Read More Specific Gravity and Water absorption test on Aggregate
The soundness of the cement is the ability to resist volume changes after hardening. The soundness test on cement is significant because,using unsound cement leads to cracks and hamper the structural quality. A sound cement is one of the key materials used in construction. Therefore it is essential to determine its quality before using it in construction. … Read More Soundness test on Cement – Procedure and Calculation
The heat of hydration is the heat liberated from the reaction between cement and water. Cement is a binding material. It consists of ingredients such as lime, Silica, Alumina etc. Water is added to cement to make it adhesive so that we can use it in construction. This article is about the heat of hydration of cement.… Read More Heat of hydration test of Cement – Process and Procedure
Surveying is a branch of civil engineering that determines the relative position of points on the earth. It is the primary process to be done to before planning a new project. The main objective of surveying is to determine the direction, horizontal distance, elevation, areas etc to draft layouts at a predetermined scale. The surveying process consists of different methods like reconnaissance, measurement, marking and plan preparation. … Read More Classification of Surveying – A complete overview
Types of Dams : Dams are large impounding structure or barriers which are outlined and constructed on a river or stream. Dams provide a wide variety of environmental, economic, and social benefits. The configuration and type of dam built should fulfil one or more purposes. This article is about the criteria for the selection of dam types.… Read More Types of Dams – 3 Classification Criteria Explained
