Concrete Thermal Conductivity Concrete thermal conductivity is a measure of the ability of concrete to transfer heat energy. It is usually expressed in watts per meter Kelvin (W m-1 K-1). The thermal conductivity of normal concrete is around 2.25 W m-1 K-1, however, it decreases linearly with increasing fractions of glass bubbles, reaching as low […]
What Is Cracking in Concrete? Cracking in concrete is caused by a variety of factors such as shrinkage, settlement, thermal movement and corrosion. Shrinkage occurs when the concrete loses moisture over time and begins to deteriorate in size. Settlement is when the underlying ground moves causing the slab of concrete to move with it which […]
What Is Board & Batten Siding? Board and batten siding is a type of siding made up of alternating thin strips of wood molding (battens) and wider boards or planks. This creates a decorative, textured, and layered effect with vertical lines that can be both chic and rustic. While it has aesthetic appeal, it can […]
What Is Outgassing In A Vacuum? Outgassing is when a non-metallic material, such as a polymer, adhesive, rubber, or potting compound/epoxy, releases gases when exposed to vacuum and/or heat. This gas can then condense on other materials attached to the outgassed part, making them unavailable for use due to contamination. Common outgassing products include printing […]
What Is Sawbuck In Woodwork? Sawbuck in woodworking is a type of sawing table used to support and steady wide or long boards so that they can be cut easily. It usually consists of two crossed legs at each end with a narrow crosspiece between them, allowing it to fold for storage. Sawbuck tables usually […]
What Is A Relief Sculpture? Relief sculpture is a type of art where figures project from a background surface, such as a wall, and are carved into it. These sculptures are traditionally classified based on how high the figures stand out from the background. Known as relievo, relief sculptures combine two-dimensional and three-dimensional elements, dependent […]
What Is A Pipe Clamp Thermocouple? A pipe clamp thermocouple is a type of temperature sensor that uses the principle of the thermocouple to measure temperatures in pipes or other cylindrical surfaces. The sensor consists of a thermocouple probe, which is a device that measures temperature by sensing the voltage generated when two different metals […]
What Is A Barrel Vault Ceiling? Barrel vault ceilings, also known as tunnel vaults or wagon vaults, are a type of vaulted ceiling that have a continuous curve from wall to wall or floor to floor. They are commonly found in historical architecture in churches and cathedrals, as well as in barns and industrial buildings. […]
What Are Field Stones? How Are Field Stones Formed? Fieldstone is a type of stone that naturally occurs near the surface of the Earth and can be found in fields. It can be a hindrance for farmers looking to expand their land, but it has also been used as a building material. It can be […]
What Is Dry Stone Walling? Dry stone walling is a traditional form of construction using interlocking stones without any mortar or cement. It involves building large walls and small boundary markers from rocks gathered from the local area. Dry stone walls are some of the oldest types of masonry structure in existence, having been used […]
