I hope this is the right place to ask this, but I am thinking of building with rammed chalk when I build a place in sussex Uk. The nature of the site means that most of these walls will be below grade. Some will be built into a bank to the rear and I am thinking of adding a basement too.
I can find very little information of rammed chalk online and only brief mentions of it in books. I know that they added 10% clay to a wall that was built out of chalk near me, But this was an interior wall above ground. I am wondering if I could stabilise the chalk with geopolymer by swapping the clay for a pozzolan - like brick dust - and adding sodium silicate and sodium hydroxide. I have made a couple of samples which look promising but I am just guessing proportions.
Does anyone know of anywhere I can find information with building with chalk, rammed, stabilised, or making chalk based geopolymers?
