THIS POST IS FOR YOUNG ENGINEERS....FOR BRAINSTORMING 1 Cum box if you fill entirely with cement, it will weigh around 1440 kgs 1 Cum box if you fill entirely with 20 mm or 10 mm aggregates, it will weight 1700 to 1900 kgs, depending on source 1 Cum box if you fill entirely with sand, it will weight around 1600 kgs 1 Cum box if you fill entirely with water, it weighs around 1000 kgs But..... If you mix them all intelligently... and fill up this material called CONCRETE in a 1 cum box... IT WEIGHS AROUND 2400 KGS !!! MUCH HIGHER THAN ALL INDIVIDUAL MATERIALS ! THIS IS CALLED PARTICLE PACKING. Can you tell how this is possible ? What is the science behind it? Cement is supposed to be heaviest of these all (highest specific gravity 3.15), but why it's bulk density is just more than water, and much lesser than aggregates? Have you thought about this? I expect youngsters to answer this 🙏

🔧 The Critical Importance of Achieving Proper Levelling in Sheet Piling 🔧 In sheet piling, precision is a necessity. Ensuring that sheet piles are driven to the correct level is paramount for several reasons, each contributing to the overall success and longevity of a project. 📏 Structural Integrity: Proper levelling of sheet piles is crucial for maintaining the structural integrity of any construction project. When sheet piles are driven to the correct level, loads are distributed evenly across the structure. This even distribution prevents uneven settlement and reduces the risk of structural failure, thereby ensuring the safety and durability of the project. 🌊 Water Tightness: In marine and flood defence projects, achieving the correct level for sheet piles is essential for creating an effective watertight barrier. This barrier is critical in preventing water ingress, which can compromise the stability and effectiveness of the structure. Proper levelling ensures that the integrity of these barriers is maintained, protecting both the structure and its surroundings. 🔨 Efficiency and Cost-Effectiveness: Starting with correctly levelled sheet piles reduces the need for subsequent adjustments and rework, which can be both time-consuming and costly. By getting it right the first time, project timelines are adhered to, and budgets are respected. This efficiency not only saves resources but also ensures that the project progresses smoothly. 🏗️ Aesthetic Appeal: In projects where sheet piles are visible, such as quay walls and bulkheads, proper levelling contributes to a professional and aesthetically pleasing appearance. A uniform and level installation reflects quality workmanship and enhances the visual impact of the project. At Steel Piling Solutions, we pride ourselves on our precision and expertise in sheet pile installation.

Interesting read about a comprehensive retrofitting strategy involving mass and stiffness redistribution to achieve seismic protection for a #corroded #concrete structure. Decades of exposure led to significant #corrosion and degradation that was corrected by #constructing new steel-concrete composite floors to increase structural mass and stiffness while reducing torsional effects of the seismic load. Article lists specifics of what was done to help the older Italian structure. On a related subject, Double Black Construction is involved with research to combat corrosion in steel structures: https://lnkd.in/enJn8jZn Canadian Construction Association - Association canadienne de la construction Canadian Steel Producers Association (CSPA) Canadian Institute of Steel Construction (CISC) Canadian Sheet Steel Building Institute Metal Building Manufacturers Association (MBMA) Metal Building Contractors and Erectors Association (MBCEA) Concrete Canada Concrete Ontario Cement Association of Canada Portland Cement Association Concrete BC Concrete Alberta British Columbia Construction Association (BCCA) VRCA - Vancouver Regional Construction Association Vancouver Island Construction Association (VICA) Council of Ontario Construction Associations Alberta Construction Association Edmonton Construction Association Calgary Construction Association Saskatchewan Construction Association Engineers and Geoscientists BC Engineers Canada Regina Construction Association Toronto Construction Association Ottawa Construction Association (O.C.A) #buildings #building #cement #concrete #metal #steel #construction

I get asked a bit why the need for screw piles? Some of the reasons why you need screw piles happen to be closely linked to how you go about determining the depth of the screw pile and/or bored pier..... Distressed structures which need to be underpinned (think leaning Tower of Pisa) usually have shallow foundations and soils that cannot support the structure for some reason. Bored piers and screw piles need to be at the right depth to be effective. #screwpiles #foundations #steel

How do we help assess a fill site's load-carrying property?   With Intelligent Compaction Measurement (ICM) technology, we’re able to identify the peak deceleration intervals of the compactor drums and see how these intervals directly relate to how compacted the surface is below.   ICM then records the location of these points through GPS technology, providing a visual map and surface records of the compacted areas, identifying the relative strength and stiffness of the material being treated. This revolutionary technology assists in determining soil parameters across the entire fill site, as opposed to limited test locations when spatial variation and heterogeneity might be present.   ICM will greatly improve the safety and performance across fill sites as it:   ✅ Identifies weak sub-surface areas or deleterious material ✅ Records and maps out compaction areas ✅ Characterizes spatial sub-grade variation over 100% of the area    For more information on Intelligent Compaction Measurement technology make sure you’re following our page to stay in the know. #DynamicCompactionSolutions #Compaction #ImpactCompaction #HEIC #GroundImprovement #ICM

#TeklaPowerFab I've noticed there are many steel fabricators are switching to Tekla PowerFab XML recently from the old KISS file. But getting the right stuff exported isn't easy. It's been tough trying to meet everyone's needs. Some clients don't want certain things, like sequence numbers or detail drawings. And others need special stuff like custom mapping for materials. It's taking up a lot of time for doing R&D. How about you detailers? Are you finding Tekla PowerFab XML tricky too, or is it going smoothly? I appreciate the tutorial videos and support provided by SDS2 and Trimble Tekla. They've been a lifesaver for us, but it can be tricky sometimes. Construction Brothers Podcast, It would be great if you guys could do some videos with folks from the Tekla PowerFab team, because it's been a trending topic within steel fabricators and detailers and many others are talking about it. With a bit of fun from you guys, there's a lot to learn. #teklapowerfab #sds2 #tekla Nexont, LLC

IS 456 2025 Is allowing a 100 mm cube for strength testing, in its new quality assurance chapter. This is because it is allowing high grade concrete M100, whose strength might sometimes cross 120 or 130 Mpa, tough to be tested in a 3000 KN CTM, which is not recommended to be loaded beyond 90% of its rated capacity due to hydraulic issues. Now, We always observe that 100 mm cubes achieve higher strengths than 150 mm cubes cast for the same concrete, sometimes more than 10 Mpa too. Also recently, AIMIL and a couple of others have come out with a 5000 KN CTM, which they tell, that it will be calibrated till 3000 KN only, and beyond that it should be linearly assumed. Now the tricky question : 1. Is a 100 mm cube representing the actual strength of concrete or 150 mm ? 2. What is the proof for the guessed answer to sl no 1 ? 3. Finally, is using a 100 mm cube better option to test high strength concrete or a 5000 KN CTM? Can you comment on this ?? The draft might come for wide circulation next month, but I would like to address this 'SERIOUS' Issue in the coming CED 2 meeting itself before wide circulation. I personally feel, officially allowing 100 mm cube along with 150 mm in IS 456 would become a 'THREAT' to quality assurance, rather than helping it. Hence, I need more discussion and debate on it please 🙏

When using prestressing concrete, this stress can be applied to the steel tendons before the concrete is placed (pre-tensioned), or after the concrete has reached design strength (post-tensioned). Pre-Tensioned (prestressed) Concrete Pre-tensioned concrete elements are precast off-site and then transported to the construction site. This, however, has historically limited the size of pre-tensioned elements due to restrictions in lifting and transportation abilities.  Common examples of pre-tensioned concrete elements include bridge beams, slabs, lintels, and water tanks. Post-Tensioned Concrete Post-tensioned structural elements are cast in situ, making them suitable for larger scale projects, such as long-span bridges or in-situ slabs.  The adaptability to onsite conditions of post-tensioned concrete and the ability to create longer spans and complex structures are key factors to the use of post-tensioned concrete, although there are additional considerations required when demolishing such structures.
