Its the BEST Day of the week. ITS CONCRETE FACTS FRIDAY!!! Check out this fun fact. Have you ever wondered how Rome’s Pantheon has managed to stay intact and remain durable for nearly 2,000 years? The Pantheon building is one of the greatest #concrete achievements of all time and was built between 113 and 125 A.D. The magic ingredient? Pozzolanic material. Researchers have found out that the ancient Romans mixed volcanic ash, a natural #pozzolan, in with the mortar to create an extremely durable concrete. This helped prevent the spread of microscopic cracks throughout. The Pantheon is one of the most celebrated wonders of the world. At the time, it had the world’s largest concrete dome at its top, measuring 142 feet in diameter. To this day, it is the oldest unreinforced dome on a structure, made entirely out of concrete with no support of structural steel. It has endured earthquakes, invasions, and natural onslaught of weather. Now That is a fun concrete fact 😎 Have a great Friday my concrete friends. #concreteFactsFriday #kingOfConcrete #Concretefacts #woc2025 #informamarkets #worldofconcrete #concretenation #concreteindustry #concreteTechnology

🇬🇧 How did Elbląg restore its Old Town? The idea of retroversion on orthophotos. Elblag is a city with a rich history, which was unfortunately destroyed at the end of World War II. Only 2 percent of the buildings in the old center survived the artillery shelling, and the remnants of the tenements were used to rebuild other cities. For many years Elblag did not have its own representative district, until 1983, when a project to rebuild the Old Town was created. This project was based on the idea of retroversion, i.e. rebuilding the city with respect for the historic street grid and the character of the facades, but with the possibility of creative interpretation by the architects. The idea was not to copy old buildings, but to create new ones that refer to previous ones. Before construction could begin, however, the site had to be thoroughly examined archaeologically. Elblag thus became one of the largest excavations in the world, where thousands of monuments and medieval foundations of townhouses were discovered. It was these that made it possible to reconstruct an urban layout reflecting the Hanseatic character of the city. Today Elblag boasts a beautiful and unique Old Town, which is the result of a reconstruction process that lasted more than 40 years. What has this change looked like over the years? You can see it on orthophotos that show the buildings, pavement, vegetation and infrastructure of this unique area from 1998 to 2022.

The Leaning Tower of Pisa: A 600-Year Earthquake Survivor 🏛️ The Leaning Tower of Pisa, a global icon, has defied gravity and stood tall for over 600 years. Its captivating tilt, a result of its construction mishap in 1173, has become a symbol of both architectural wonder and resilience against earthquakes. 🔧 Ingenious Design Craftsmen of old ingeniously tackled the tower's tilt by incorporating longer columns, asymmetrical decorations, and adjusting its height. The tower's completion in 1372 marked a triumph of craftsmanship over adversity. 🔧 Modern Reinforcements In the late 20th century, restoration work strengthened the tower's foundations and introduced 800 tonnes of lead counterweights. This intervention almost straightened the tower by a degree, ensuring its stability. 🌍 Beneath the Surface Recent research reveals that the tower's inclination has been its saving grace. Layers of sand and clay in the ground allow the tower to move with the earth's shifting during earthquakes, diffusing their impact. ⚙️ Unconventional Response Unlike regular buildings that sway along a vertical axis during earthquakes, the tower rotates around its inclined axis. This unique response dissipates the energy that could harm its structure. 🔮 A Promising Future Thanks to meticulous restoration, the tower is expected to defy earthquakes for another 300 years. Its tale showcases the synergy of history, engineering, and nature, and holds lessons of innovation and resilience. #LeaningTowerOfPisa #Architecture #Engineering #Resilience #Earthquakes #Innovation #geology

💥Impactful Integrity Calton Hill 💥 Situated within a World Heritage Site, the Calton Hill project encompassed the redevelopment of existing listed buildings: The City Dome, The City Observatory and Transit House, and a new Contemporary Art Gallery and Restaurant within the 1818 Playfair-designed City Observatory. HarrisonStevens worked with the joint clients Collective Gallery and the City of Edinburgh Council to develop a design including a site-wide response to visitors' journey to the new facilities. The existing route through the Observatory was redefined and graded to become fully accessible. The use of steps was minimised, while striking Whinstone retaining walls became a significant part of the proposals, defining the sequence of spaces across the steeply sloping site. The planting palette – predominantly grasses and meadows – adds to the site’s key concept and observation experience and illustrates the seasons' passing. There is a predominance of perennials and grasses, a proportion of which are native, including some you might readily find on the adjacent Arthur’s Seat or within a similar Scottish landscape. It was imperative to acknowledge and respond to the anticipated life costing and maintenance of the design. To celebrate the site’s volcanic origins and retain its exposed, excavated geology, we reclaimed basalt for paving and aggregate. This approach was not only contextually rich, but demonstrative of a resource-conscious and low carbon footprint associated with the re-use of site-won materials. Native topsoil, harvested, stored, and processed on site, was an ecological and pedological valuable resource, holding a rich seedbank of grasses within it. The external environment of this site transcends both the new and old, the near and far, the natural and the cultivated. In the context of union between the traditional and contemporary, the re-opening of this wonderful site to the public after 60 years offers both reflection and prospect. #Integrity #CaltonHill #Edinburgh #LandscapeArchitecture #Heritage

Coinciding with the fateful #earthquake in #Morocco in which rammed earth and masonry constructions have been responsible for the deaths of thousands of people, this week at #SAHC2023 (Structural Analysis of Historical Constructions) in #Japan we are presenting our studies on the reinforcement of this type of structure, which we are carrying out thanks to funding from the State Research Agency from the Spanish Ministerio de Ciencia e Innovación.  https://lnkd.in/dcQymkDQ F.

The celestial entrance known as 'Heaven's Gate' is located within the breathtaking Tianmen Mountain in China. Situated approximately 5,000 feet above sea level, Tianmen Cave in China is the world's highest naturally formed arch. Accessing this remarkable landmark involves ascending 999 steps, referred to as the "stairway to heaven," where the number nine holds significant meaning in Chinese numerology, symbolizing good fortune and eternity. Alternatively, visitors can opt for a bus ride along a narrow roadway. With dimensions reaching about 430 feet in height and 190 feet in width, the cave was once an ordinary cavern. However, in 263 A.D., a section of the mountain's cliff collapsed, giving rise to the captivating appearance of a "portal to heaven" that mesmerizes observers to this day. #design #constructionconsultancy #construction #cmc #pmc #constructionExperts #innovation #interiordesign #truekeey

Stone, whether igneous, sedimentary, or metamorphic, has been a vital building material throughout human history, and its significance left an indelible mark on architecture and culture. What makes stone so fascinating is its remarkable strength as well as its ability for intricate and delicate carvings. From ancient monuments to modern architecture, stone remains an enduring symbol of durability, functionality and tangible evidence of cultural history. Stone conservation can be challenging depending on the characteristics of the material, inherent discrepancies, cause of weathering, and level of deterioration. It requires thorough investigation, scientific analysis, and balancing conservation interventions safeguarding the stone’s long-term stability. #granite #sandstone #marble #limestone #travertine #schist #slate #brownstone #stoneconservation #stonedeterioration #rocksrock #rocknroll #igneous #sedimentary #metamorphic #stonecarvings #geology #getrocked #rockofages #stone #stoned #stonework #therock #rockhard
