More cement in a mix means better adhesion — but this does not make the mix stronger. Sand – 700 kg. Sand helps to prevent air pockets from forming in a mix by filling out the empty spaces between aggregates. Air pockets will greatly undermine the strength of concrete, but by binding to the cement and water, sand will ensure consistency.
