Calculating the unit weight of steel bars with various diameters is crucial when creating a schedule for bar bending. The total weight of steel bars/TMT bars weight required for the project’s construction can be calculated once we know the unit weight of steel.
Shrinkage of concrete refers to the reduction in its volume over time, primarily due to moisture loss and chemical reactions during hydration. This phenomenon can lead to shrinkage cracking of concrete, compromising structural integrity and durability. Understanding what shrinkage of concrete is involves recognizing its various forms, such as drying shrinkage, autogenous shrinkage, and thermal shrinkage.
Concrete road construction involves building durable pavements using cement concrete road techniques, which prioritize strength and longevity. This method uses layered systems called concrete road layers, including subgrade, sub-base, base, and surface layers, to ensure stability and load distribution. Unlike asphalt, road construction concrete offers higher resistance to weather, heavy traffic, and wear, reducing long-term maintenance costs.
Slipform shuttering is a continuous construction method where concrete is poured into a continuously moving formwork, allowing for the seamless creation of vertical structures. This technique, known as slipforming, enables the efficient construction of tall edifices such as silos, chimneys, and core walls in high-rise buildings. By employing slipform formwork, builders can achieve monolithic structures without horizontal joints, enhancing the overall strength and durability of the construction.
Eutrophication in US freshwaters costs approximately $2.2 billion per year. Astonishing, right? Want to know more about this process that can wreak havoc if left unchecked? In this blog, let’s visit a eutrophied lake and understand the entire events that lead to eutrophication and its effects.
Furnace bottom ash (FBA) is a waste material, it generally has no pozzolanic property, and hence it cannot be utilised as a cement substitution material like fly ash. Pond ash is a waste product from coal-based power plants. the workability of the pond ash concrete (PAC) reduces with the increase in percentage of fine aggregate replacement
A Welding Procedure Specification (WPS) is essential for achieving precise and high-quality welds. It outlines the steps, parameters, and guidelines that ensure consistent and flawless welding results. But what is a WPS in welding? Simply put, it’s a detailed document that defines the weld specification, including joint configurations, welding process, and filler material.
Weld inspection is crucial for ensuring the quality and safety of welded joints. This applies across various industries, including construction, automotive, and manufacturing. This critical process verifies that welds meet rigorous industry standards, identifying any defects that compromise performance or safety. Weld inspection combines visual inspection with advanced non-destructive testing (NDT) methods, such as radiography and ultrasonic testing, to detect surface and subsurface flaws. Certified Welding Inspectors (CWIs) are accredited by organizations like the American Welding Society (AWS) or CSWIP. They play a key role in overseeing these inspections. They also uphold quality standards.
All cement price list today is the most important update every construction engineer and civil engineering construction firm should be familiar with. Cement is the most significant and widely used construction material which forms an integral part of any structure.
Development length is an essential concept in civil engineering that refers to the length of reinforcement required to transfer the force from the steel reinforcement to the surrounding concrete. It is crucial in ensuring that the reinforcement is effectively bonded to the concrete to resist the applied forces. “The development length depends on several factors, including the diameter of the bar and the strength of the concrete.
