How To Mix Vermiculite Concrete:
Materials needed:
1 No. 100 litre bag of DINEEN Vermiculite (approx. 6 parts by volume). 18kg of Portland cement or Cement Fondu (approx. 1 part by volume) 23 litres (5 gallons) of water.
This mix (6:1) will make about 0.1m³ of lightweight concrete. For 8:1 use 14kgs of Cement.
Pour vermiculite from the bag into mixer, add the correct proportion of Portland cement, mix together and add the water – do not make or use a sloppy mix.
The vermiculite concrete can then be placed and lightly tamped into position. Do not compact heavily.
