    Binding material is the main element of a concrete mix. Cement is the most commonly used binding material. Lime could also be used. When water is mixed with the cement, a paste is created that coats the aggregates within the mix. The paste hardens, binds the aggregates, and form a stone-like substance. Aggregates. Sand is a fine mixture
