Kennedy’s Silt Theory According to what I know, Kennedy’s Silt Theory states that the vertical eddies rising from the bed of an alluvial channel are responsible for keeping silt particles in suspension. The theory defines a critical velocity that will prevent silting or scouring. Kennedy’s equation relates the critical velocity to the...
Relation Between Duty, Delta, and Base Period To understand the relation between duty, delta, and base period in the context of irrigation engineering, we can break it down step by step: The relationship between duty (D), delta (Δ), and base period (B) can be expressed as follows: If field area...
Types of Shear Failures in Soils Shear Failures in Soils are categorized into three primary classes: general shear failure, local shear failure, and punching shear failure. Thanks for Visiting 🙂
Field Test on Sand When conducting a field test on sand, there are several aspects to consider, including its composition, behavior under different conditions, and potential applications. Field tests on sand are crucial in various industries such as construction, geotechnical engineering, environmental science, and agriculture. These tests help in understanding...
Strip Footing A strip footing, also known as a continuous footing, is a type of shallow foundation used to support a load-bearing wall or a line of columns. It is a long strip of concrete that extends the entire length of the wall and spreads the load over a larger...
Introduction Non-destructive testing (NDT) is a crucial process in the construction and maintenance of concrete structures. It helps to evaluate the integrity and performance of the concrete without causing any damage to the structure. This essay discusses the importance of NDT tests on concrete and how these tests contribute to...
Water-Cement Ratio The water-cement ratio is a crucial parameter in the concrete industry, as it directly affects the properties of the final product. A lower water-cement ratio results in a denser, stronger, and more durable concrete, while a higher ratio leads to a more porous, weaker, and less durable concrete....
Cement Testing: An OverviewCement is a vital construction material used worldwide in various applications, such as concrete production, mortar, and grout. The quality and performance of cement are crucial for the success of construction projects. To ensure the cement meets the desired standards and specifications, several tests are conducted. In...
Types of Cement Cement is a crucial building material used in construction for binding materials together. There are various types of cement, each with its own unique properties and applications. The most common types of cement include: 1. Ordinary Portland Cement (OPC): This is the most widely used type of...
Strap Footing A strap footing, also known as a combined footing, is a type of foundation that is used to support two or more columns in close proximity to each other. It is designed to distribute the load from the supported columns over a wider area of soil to prevent...
A raft foundation, also known as a mat foundation, is a type of foundation that is used to distribute the load of a structure over a large area. It is commonly used when the soil has low bearing capacity or when the loads from the structure are expected to be...
Young’s Modulus Young’s modulus, also known as the elastic modulus, is a measure of the stiffness of a material. It quantifies the relationship between stress (force per unit area) and strain (proportional deformation) in a material undergoing tension or compression. The modulus is named after Thomas Young, a 19th-century British...
Rigid pavements, also known as concrete pavements, are commonly used in road construction due to their durability and long service life. However, like any other infrastructure, rigid pavements can experience failures over time. These failures can be attributed to various factors such as design flaws, construction issues, environmental conditions, and...
Rolled Steel Beams in India In India, rolled steel beams are classified into five series based on their dimensions and strength, as per the Indian Standards. These series include ISMB, ISJB, ISLB, ISHB, and ISWB. Each series has its own specifications and applications, and understanding these categories is essential for...
The constant head permeability test is a laboratory test used to determine the permeability of a soil sample. Permeability refers to the ability of a soil to allow water to flow through it. This test is commonly conducted in geotechnical engineering and hydrogeology to assess the suitability of soils for...
