What Is Meant By Roller Compacted Concrete? Roller Compacted Concrete (RCC) is a type of concrete that is prepared with basic ingredients such as gravel or crushed stone, sand, cement and water, which are mixed together to form a stiff asphalt like material. This material is then mixed with a mechanical compaction device known as […]
What Is A Pavement Condition Index (PCI) The Pavement Condition Index, also known as PCI, is a numerical value between 0 and 100 used to grade the condition of pavement section surfaces. The PCI, or Pavement Condition Index, is a tool used by various industries, including transportation civil engineering, and asset management, to assess the […]
What Is Meant By Polymer Concrete? Polymer concrete is a composite material that uses a binder made of polymer resin and filler materials such as sand, crushed stone, or gravel. It is similar to traditional concrete but is much more durable and flexible due to the addition of the binding agent. Polymer concrete has increased […]
What Is A Oriented Strand Board (OSB)? Oriented strand board (OSB) is a type of wood panel made by compressing and bonding together strands of wood with adhesives. It was first invented in California in 1963. OSB is often used in construction for load-bearing applications, such as sheathing in walls and floors, and roof decking. […]
What Is Alkali-Silica Reaction in Concrete? Alkali-silica reaction (ASR), also known as “concrete cancer,” is a chemical reaction that can occur between the alkaline hydroxides in cement and certain types of aggregate. This reaction can cause damage to the concrete in a building and may require extensive repairs or even demolition. ASR is the most […]
What Does Sulfur Do To Concrete? Sulfur is an important additive to concrete, as it helps to increase the strength and durability of the finished product. When sulfur is added to concrete blends, it reacts with the cement paste to create a new type of calcium silicate hydrate (CSH) that has a higher level of […]
What is Self-Consolidating Concrete? Self-Consolidating Concrete (SCC) is a high-performance concrete which has the ability to spread freely, fill formwork and encapsulate reinforcement without the use of mechanical consolidation. It utilizes a special blend of aggregates, admixtures, and cementitious materials designed to achieve an optimal combination of flowability, passing ability, segregation resistance, and stability. SCC […]
What Is Tamping In Construction? Tamping is a construction technique used to compact the soil or fill material by repeatedly striking it with a hand tamper, plate tampers, or a power tamping machine. The purpose of tamping is to provide a better and stronger foundation for the construction project and to avoid settling issues in […]
What Is A Efflorescence in Concrete? Efflorescence is a white powdery substance that can appear on the surface of the concrete. It is caused by water vapor carrying dissolved salts to the surface of the concrete where they are left behind as the water evaporates. Efflorescence can occur in natural and man-made environments and may […]
What Is Roman Slate Concrete Stamp? Roman Slate Concrete Stamp is a process that adds texture and depth to concrete surfaces. It creates the look of stone slabs, natural slate, and other rustic textures when stamped on wet concrete. The technique uses rubber mats with raised designs that are pressed into fresh concrete while it’s […]
