Sep 22, 2020 · Sugar is very effective, even in minute quantities. To such an extent that, an excess of sugar content in the concrete mix by weight of 0.2% will impede the hydration reaction completely. As a result, the concrete will never set, and collapse immediately once the shuttering is removed. This process is known as Killing of Set.
