Also known as Concrete Mix, or Premix. Contains a mix of 14mm Metal and Washed Sand. Used for making concrete. We use a 50/50 mix with more metal to give more strength in its bonding. Mix at a 5 mix -1 cement powder to give a 15-20 MPA strength. A cubic metre of concrete requires 2 tonne of mix and 16x 20kg bags cement powder
