The limestone acts as a seed crystal for the cement, better distributing the reaction products and increasing the reactivity of the cement. As there is always unhydrated cement in the concrete, this change will have no real measurable effect on the use of fly ash. The cement might have a reduced water demand, and the coarser …

The aggregate must be washed before used in concrete in the case of excess on the permissible dust content. The fine-grained material obtained in this way is a dusty waste. It can be pointed out that the classification of dust as a deleterious additive in concrete solely on the basis of its grain size is incorrect [13,29]. As indicated earlier ...

Using decomposed granite with the addition of stabilizers or resins can extend the life of the paving. This however requires the use of proper mixing equipment or can be bought premixed from certain suppliers. The costs of these additives do reduce economy, but the increased life extending up to ten years can more than make up for this.
