How can we interpret the results of durability tests on concrete like sulphate attack or acid attack on concrete say loss of strength or weight?

Generally durability of concrete is determined by curing concrete in 5% or so solutions of H2SO4 or HCl and the loss of strength and weight is determined. I guess they only give the relative...
