hello , good idea to start out thinking of the volumes and amount required ,my own on- going projects required building a 55 foot by 30 foot shed with a
concrete floor to store bales of material ,bags of lime by the pallet load , and store /shelter the mixer and telehandler plus myself out of the elements so i could mix and pour at my own pace----a perhaps bit over the top but i cant see how i could have managed or progressed through out the year . The bales i have hold 25 kilograms of compressed material which make up 200 liters by volume of final mix , so that times 5 gives me one cubic meter of mix , so the next step is to do measurements of wall s floors ,roofs by length ,height and thickness or depth of insulation you want ,break this it down into a wall or floor section at a time then add them all up to give a rough total volume.This volume wont change much by adding in the proportions of lime and binder plus water to it---but its total weight will --which will decrease again as it dries out .The costs of material and delivery are cheaper in bulk of course and thats were having your own loader pays off , and for my situation provided the power source for the mixer , another bespoke requirement for large batch making ---i found there was too much time and effort wasted mixing up small volumes ---less than 200 liters for me . It can be done by hand , i have done so when forced to ---telehandler blew a hydraulic hose ---and it was a few weeks down ---so it was back to manual labour ---i used an old bath tub and pitchfork --and it was an effort but not as bad as it sounds---extra help on carrying the buckets of mix was greatly appreciated though , and lots of determination required, cheers
