Variable density is often as little as three hundred kg/m3,[seventeen] While at this density it might have no structural integrity in the least and would function to be a filler or insulation use only. The variable density cuts down strength[seventeen] to enhance thermal[17] and acoustical insulation by changing the dense large concrete with air or a lightweight substance which include clay, cork granules and vermiculite.
