Default vermicrete

not sure that last posting posted -- I am attempting to calculate how much Portland cement and vermiculite I need to purchase. I have a 6 ft by 7 ft with a 4 inch depth. Need a 5 10 1 ratio -- any help?

That sounds like 14 cf to me of vermiculite. Get some extra, maybe one or two cf if you can. A 5 : 1 ratio should need 3 bags of 90# portland. I dry mixed the vermiculite and portland by pouring the portland over the vermiculite and then mixing that. then add water to get oatmeal consistency.

For every 10 parts vermiculite add about 3 parts water. I mix the cement and vermiculite dry first then add the water. You will lose around 20% in volume when you mix the water in so this needs to be accounted for.
