  • maxit LWA can be used as a lightweight insulating material in any number of Civil Engineering Applications
  • Transcript

    • 1. L I G H T W E I G H T F I L LFOR CIVIL ENGINEERING<br />
    • 2. L I G H T W E I G H T F I L LFOR CIVIL ENGINEERING<br />What is maxit Leca?<br />
    • 3. L I G H T W E I G H T F I L LFOR CIVIL ENGINEERING<br />maxit Leca was developed in Norway in 1958 to provide insulation to roads and railways across Scandinavia.<br />It is a lightweight expanded clay formed by heating & firing natural marine clay in a rotary kiln at temperatures up to 1150 degrees centigrade.<br />
    • 4. L I G H T W E I G H T F I L LFOR CIVIL ENGINEERING<br />What are suitable applications for maxit Leca?<br />
    • 5. L I G H T W E I G H T F I L LFOR CIVIL ENGINEERING<br />Drainage<br />Protecting and insulating service pipework<br />Reducing the loads against retaining walls<br />Stabilising slopes<br />Biofilters<br />Void Filling <br />
    • 6. L I G H T W E I G H T F I L LFOR CIVIL ENGINEERING<br />Lightening the loads on bridge abutments<br />Minimising earth settlement<br />Lightweight insulating material in any number of Civil Engineering Applications<br />
    • 7. L I G H T W E I G H T F I L LFOR CIVIL ENGINEERING<br />Why Specify maxit Leca?<br />Low density and high strength combined with easy handling make expanded clay a highly competitive product.<br />
    • 8. L I G H T W E I G H T F I L LFOR CIVIL ENGINEERING<br />Eliminates costly settlement periods<br />Reduces weight on underground voids<br />Eliminates or reduces expensive load transfer techniques<br />
    • 9. L I G H T W E I G H T F I L LFOR CIVIL ENGINEERING<br />A free draining material<br />Installed using the same machinery as conventional fills<br />Also can be installed pneumatically into areas of reduced or awkward access<br />maxit Leca can be compacted in 1m layers, rather than 225mm as with traditional fill materials<br />
    • 10. L I G H T W E I G H T F I L LFOR CIVIL ENGINEERING<br />Any surplus product is easily reclaimed and re-utilised<br />maxit Leca is not susceptible to oil or diesel spills<br />Has superb insulating properties, protecting against frost<br />It contains no harmful substances or gases & is absolutely neutral & chemically inert. <br />
    • 11. L I G H T W E I G H T F I L LFOR CIVIL ENGINEERING<br />Application Scenarios<br />Quay Walls<br />Tunnels<br />Insulating Pipelines<br />
    • 12. L I G H T W E I G H T F I L LFOR CIVIL ENGINEERING<br />When used against RETAINING WALLS maxit Leca will reduce the weight acting on the rear of the structure by at least 75%, in comparison to traditional fill materials. This weight reduction avoids potential failures & enables savings by increasing spacing between buttress walls & reducing structural dimensions.<br />
    • 13. L I G H T W E I G H T F I L LFOR CIVIL ENGINEERING<br /> maxit Leca's ability to reduce settlement can offer massive benefits, reducing timescales from years to a few months <br /> By installing maxit LWA, subsoil strengthening & lengthy settlement can be<br /> reduced or even avoided <br /> altogether. <br />
    • 14. L I G H T W E I G H T F I L LFOR CIVIL ENGINEERING<br /> Use of maxit Leca on green areas such as SPORTS FIELDS ensures optimum drainage whilst improving thermal protection thus assisting with the creation of a sympathetic <br /> habitat for plant life.<br />
    • 15. L I G H T W E I G H T F I L LFOR CIVIL ENGINEERING<br />Using maxit Leca (loose or mixed with cement) to fill underground CAVITIES reduces structural forces & eliminates subsidence issues. <br />By pumping high quantities of maxit LWA per day, it is possible to obtain a complete filling of the cavity with high drainage capacity, good resistance and a stiffness similar to that of the original ground.<br />
    • 16. L I G H T W E I G H T F I L LFOR CIVIL ENGINEERING<br />SKANSKA UK CIVIL ENGINEERING<br />Unexpected voids were discovered behind the abutments of a Victorian Bridge during a major £8 million project at Harthope Viaduct nr. Moffat, Scotland.<br />By using maxit’s 55m³ blowing vehicle, Skanska were able to deliver maxit Leca from ground level, filling 5 voids up to 10m in depth & up to 1.5m wide in just a single day. <br />
    • 17. L I G H T W E I G H T F I L LFOR CIVIL ENGINEERING<br />How Lightweight is maxit Leca?<br />
    • 18. L I G H T W E I G H T F I L LFOR CIVIL ENGINEERING<br />Typical Comparison<br />Concrete Gravel = 2403kg.cu.m<br />maxit Leca = 280kg.cu.m<br />maxit Leca = 15% of the weight of traditional backfill material<br />
    • 19. L I G H T W E I G H T F I L LFOR CIVIL ENGINEERING<br />So What Next?<br /><ul><li> You will be requiring further technical information?
    • 20. You now have the answer to a design issue?
    • 21. You have an application idea?
    • 22. You require a lunchtime CPD?</li></ul>YES?<br />
