What is the stoichiometric water level in a concrete mix?
It is the theoretical exact water content required for hydration process.
The water to cement (w/c) ratio is a basic parameter in concrete technology. The theoretical water to cement ratio strictly necessary for the hydration reaction is called stoichiometric ratio.
The exact amount of water that is needed for the hydration of cement in a mix.
Can two types of cement be used simultaneously in one recipe for concrete composition? (The first is cement as a binder and the second as sealing the graining structure).
