Concrete Mix Design Instruction

  1. 1. CONCRETE MIX DESIGN <ul><li>10 Essential Things to Remember </li></ul><ul><ul><li>http://CivilEngineerBlog.com/ </li></ul></ul>
  2. 2. 10 Things to remember during Concrete Mix Design <ul><li>Good quality concrete starts with the quality of materials, cost effective designs is actually a by-product of selecting the best quality material and good construction practices. </li></ul>
  3. 3. 10 Things to remember during Concrete Mix Design <ul><li>Following are 10 Things to remember during Concrete Mix Design and Concrete Trials. </li></ul>
  4. 4. 1. Standards for Mix design <ul><li>ACI and other standards only serves as a guide, initial designs must be confirmed by laboratory trial and plant trial, adjustments on the design shall be done during trial mixes. </li></ul><ul><li>Initial design “on paper” is never the final design. </li></ul>
  5. 5. 2. Trial Mixes <ul><li>Always carry out trial mixes using the materials for actual use. </li></ul>
  6. 6. 3. Design Variation Tests <ul><li>Carry out 2 or 3 design variations for every design target. </li></ul>
  7. 7. 4. Safety Factors <ul><li>Consider always the factor of safety, (1.125, 1.2, 1.25, 1.3 X target strength) </li></ul>
  8. 8. 5. Material Sources <ul><li>Before proceeding to plant trials, always confirm the source of materials to be the same as the one used in the laboratory trials. </li></ul>
  9. 9. 6. Batching Plant Calibration <ul><li>Check calibration of batching plant before trials </li></ul>
  10. 10. 7. Tests at Batching Plant <ul><li>Carry out full tests of fresh concrete at the batching plant, specially the air content and yield which is very important in commercial batching plants </li></ul>
  11. 11. 8. Quality Control <ul><li>Correct quality control procedures at the plant will prevent future concrete problems </li></ul>
  12. 12. 9. Admixture <ul><li>Follow admixture recommendations from your supplier </li></ul>
  13. 13. 10. Strength Development Check <ul><li>Check and verify strength development, most critical stage is the 3 and 7 days strength </li></ul>
  14. 14. Important note: <ul><li>Technical knowledge is an advantage for batching plant staff, even if you have good concrete design but uncommon or wrong procedures are practiced it will eventually result to failures </li></ul>
  15. 15. Further Resources for Concrete Industry <ul><li>Check out these websites: </li></ul><ul><li>http://CivilEngineerLink.com/ </li></ul><ul><li>http://CivilEngineerSite.com/ </li></ul><ul><li>http:// CivilEngineerBlog.com / </li></ul><ul><li>THE END </li></ul>
