<p>A process for producing a dry Lime and sand mix comprising aggregates and a lime-based binder is disclosed which is characterised by the successive steps of:a) admixing a pre-determined quantity of calcium oxide (CaO) containing compound with wet aggregates, said aggregates having a predetermined free water content;b) providing a period of storage; andC) admixing at least one hydraulic component or binder wherein the amount of calcium oxide used is in the range of 109 to 280 wt% of said free water content or, alternatively, of 35 to 90 mol% of said free water content. The lime may be in the form of quicklime. The hydraulic binder may be Portland cement, ground granulated blast furnace slag, fly ash, silica fume, metakaolin or natural hydraulic lime.</p> |
