DISCLAIMERS
  1. The volume requirement for sand and stone takes into account a reasonable wastage factor of 15%.
  2. No wastage factor was used for the determination of cement requirement.
  3. The mix ratios were determined from laboratory trials on standard water / cement ratios.
  4. Trial mixes were conducted on aggregates that conform to the SANS 1083 specification.
  5. Desired concrete properties are only achieved with good concrete practices (batching, placing, curing).
