What Is Meant By Bleeding Of Concrete? Bleeding of concrete is the process in which excess water from a freshly mixed concrete mix rises to the surface, causing a thin layer of water on top. This occurs because of the difference in water content between the thicker mortar at the bottom and the drier sand […]
What Is A Concrete Insulation? Concrete Insulation is a type of insulation material used in building structures to reduce energy consumption. It has thermal, acoustical, and moisture-resistant properties, which help keep the interior temperature of buildings stable and reduce noise levels. Special lightweight aggregates meeting ASTM specifications C332 or performed or formed-in-place foam are commonly […]
What Does Carbon Footprint Means In Buildings? Carbon footprint in buildings means the total amount of carbon dioxide emissions that are generated by building activities, such as energy consumption for heating, cooling and lighting as well as emissions from construction materials and processes. Reducing a building’s carbon footprint is important to conserve energy and reduce […]
What Is Energy Efficiency In Concrete? Energy efficiency in concrete describes the ability of concrete to act as a thermal mass. This term refers to the property of concrete materials to store and slowly release heat over time, which can help moderate interior temperatures in buildings. Buildings with this thermal mass typically remain cooler during […]
What Is A Life Cycle Assessment, And Why Is It Important? Life Cycle Assessment (LCA) is a systematic approach to assessing the environmental impacts of products over their entire life cycle, from raw material extraction to production, use and disposal. It considers the impact of resource use and emissions on air, water, and land and […]
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 […]
