What Is Cement Clinker? Cement clinker is a solid material made during the production of Portland cement. It is formed by heating a mixture of raw materials, including limestone and clay, to high temperatures in a kiln. The resulting clinker consists mainly of four minerals: alite, belite, tricalcium aluminate and calcium aluminoferrite. These minerals are […]
What Is Longitudinal Cracking in Pavement? Longitudinal cracking is a type of pavement distress that occurs when cracks form along the direction of traffic flow. This type of cracking often happens as a result of temperature fluctuations, overloads or vibrations due to high-speed traffic and occurs when asphalt layers fail to bond correctly. Longitudinal cracks […]
What Is Alligator Cracking In Asphalt Roads? Alligator cracking, also known as crocodile cracking, is a type of surface failure characterized by interconnected cracks forming in asphalt pavement. It is caused by fatigue or stabilization from the weakened subgrade beneath it and water seeping into the pavement. Alligator cracking can be minimized through preventative maintenance […]
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 Asphalt Stripping? Asphalt stripping is essentially the opposite of asphalt raveling. Rather than the top layer disintegrating and exposing the lower layers, it is the lower layers that fall apart first, weakening and damaging the upper ones. More specifically, aggregate materials and asphalt binder at the bottom of the asphalt layer start to […]
What Is Block Cracking In Flexible & Rigid Pavement? Block cracking in pavement is a type of distress that occurs due to environmental factors such as temperature extremes, moisture, and ultraviolet radiation. In pavements, the stress or strain is usually caused by thermal stresses or curling of the concrete slab causing joint/crack misalignment or shrinkage […]
What Is A Corrugation In Pavement? A corrugation in pavement is an irregular wavy pattern that forms on the surface of asphalt or concrete roads. It is caused by several factors such as poor drainage, heavy traffic, and improper construction methods. Corrugations can range from small bumps to deep ruts that make driving difficult and […]
What Is A Transverse Cracking in Concrete Pavement? Transverse Cracking is a type of cracking caused by tension forces perpendicular to the direction of applied loads. It often occurs when normal traffic causes the pavement surface to flex in response to the loads and can be seen as parallel cracks running along the road surface […]
What Is The Purpose Of A Cavity In A Wall? The purpose of a cavity in a wall is to provide additional insulation against temperature and noise variations, prevent structural movements due to external forces and decrease air infiltration. Cavity walls also serve an important aesthetic purpose by helping create visual depth and dimension. They […]
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. […]
