What Is Contour Strip Mining? Contour strip mining is a method of extracting minerals from hilly areas where the mineral is exposed at the surface at a consistent elevation along the hillside. This method involves the removal of the overburden, which is the soil and rock covering the mineral deposit, starting at the outcrop and […]
What Is Mandrel Bending? Mandrel bending is a method of rotary draw bending used to shape pipes and tubes. The process involves inserting a mandrel, a solid shaft with segmented balls, into the pipe or tube before bending it. The mandrel provides internal support to the pipe or tube during bending, which helps prevent collapse […]
What Is Concrete Coring? Cutting a round hole in a concrete structure through the use of a diamond-tipped drill is known as concrete coring. This method is preferred due to its low noise level, lack of dust, and non-percussive nature. Collecting rock and sediment samples for geological research can be done using a technique called […]
What Is A Concrete Chipping? Concrete chipping is a process that involves breaking away dried concrete from the walls of ready-mix concrete trucks and central mixers. This task is typically carried out by trained professionals or by a robotically-controlled machine that uses an ultra-high pressure water source (20,000 psi) to delaminate the concrete from the […]
What Is Framing Square? A framing square, also known as a steel square or carpenter’s square, is a versatile tool that is commonly used by carpenters, general contractors, masonry contractors, and DIY enthusiasts. The tool is L-shaped and is mainly used to create clean angles and to measure joints, joists, and planes. The tool’s primary […]
What Is A Black Chrome Plating? Black chrome plating is a coating of chromium that has been chemically altered to achieve a black color. This type of plating is applied electrostatically to a metal surface, such as an automobile wheel or a motorcycle exhaust pipe. The finished product is a durable, conductive, corrosion-resistant, ultra-violet light-resistant […]
What Is A Cistern Tank? A cistern is a container that is used to store liquids, typically water, and is designed to prevent leaks. It is commonly used to collect and store rainwater. Unlike wells, cisterns have a lining that prevents water from seeping out. They come in a variety of sizes, from small to […]
What Is A Lally Column? A Lally column is a type of structural support column made of thin-walled steel and filled with concrete. It is designed to provide support to beams or timbers stretching over long spans and is commonly used in construction projects. The steel shell of a Lally column is filled with concrete, […]
What Is An Acrylic Paint? Acrylic paint is a quick-drying medium made of pigments suspended in a polymer emulsion and various other ingredients such as plasticizers, silicone oils, and stabilizers. It is typically water-based, but becomes water-resistant once dry. The finished product can resemble a watercolor, gouache, or oil painting depending on how it’s diluted […]
What Is Concrete Strengthening? Concrete strengthening is a technique used to increase the strength of existing concrete structures. It is commonly achieved through the use of steel reinforcements such as steel bars, carbon fiber reinforcement, even fiber-reinforced polymer which are placed in the concrete before it sets and cures. This process strengthens the structure by […]
