What is a geogrid? A geogrid is a two-dimensional geosynthetic material designed to provide tensile reinforcement for soil and aggregate layers in civil engineering projects. Geogrids are manufactured from high-tensile polymers, such as polyester, polyethylene, or polypropylene, and are characterized by a fixed aspect ratio with intersecting ribs and apertures, which refer to the voids… Continue reading Geogrid
What is a geocomposite: definition, types, uses and materials Geocomposites is defined as a combination of two or more geosynthetic products, used for specific applications in civil engineering. Geocomposites can be made by pairing products such as geonets, geomembranes, geogrids, or geotextiles. They are designed to solve specific geotechnical challenges with soil terrains, or topographical situations. For… Continue reading Geocomposite
What is a geocell, its working principle and why is it necessary in geotechnical engineering? A geocell is a three dimensional hollow cellular confinement system, which is used to confine soil in honeycomb structure. It is comprised of a matrix of several honeycomb-like structures which are interconnected [either by bonding or extrusion] with each other… Continue reading Geocell
What is a gabion wall? The gabion wall has been widely used as a structural framework in civil engineering and landscaping work because of its strength and flexibility. It originates from the Italian word “gabbione,” which literally means “big cage.” The wire mesh cages are filled with materials like rock, concrete, or, in some cases,… Continue reading Gabion wall
Geotextiles, geomembranes, geocells, geonets, geotubes, uniaxial geogrids, biaxial geogrids, geocomposites, and many more are all types of geosynthetic materials that play a pivotal role in modern engineering and environmental management. These innovative materials are manufactured from synthetic polymers and are designed to enhance the performance and durability of civil engineering projects. Geosynthetics are versatile and… Continue reading Functions of geosynthetics
Freeze-thaw weathering: Its effect on road pavements Frost penetration and thawing cycles can be a daunting task for the streets and buildings when the winter sets in. This process happens naturally but it can be very harsh on the road pavements over time as it causes cracks, erosion and even very serious damage. What is… Continue reading Freeze thaw weathering
What does flexural rigidity mean? Flexural rigidity is the ability of a material to resist bending under an external force. In civil engineering, it is one of the critical parameters that influence the way structural elements such as beams, slabs, and planks respond to applied loads. The formula for flexural rigidity is obtained by multiplying… Continue reading Flexural rigidity
What is a fencing net? A fencing net is a sort of barrier netting made up of a mesh of either flexible or rigid material, designed to enclose areas, ensure safety, or restrict access. Application areas of such nets are quite diverse and serve certain basic functions around residential and commercial premises, agricultural lands, and… Continue reading Fencing net
Overview of fatigue Fatigue can be defined as progressive loss of a material resistance due to repeated stress or strain. With time, even the most resilient materials develop cracks or breaks due to constant load cycles. Therefore, understanding these processes is of extreme importance for predicting the durability and reliability of materials used in various… Continue reading Fatigue life
What is fatigue cracking? Weariness splitting is a typical type of crumbling in structural materials, especially in asphalt and common buildings. This happens when a material like black-top or cement is exposed to rehashed rounds of stress or strain that bit by bit corrupt its basic uprightness over the long run. Dissimilar to prompt breaks… Continue reading Fatigue cracking
