cement amounts can be reduced because concrete strength is directly related to the water/cement ratio. Definition of Mineral Admixtures Mineral admixtures include fly ash, hydrated lime, silica fume and ground blast furnace slag. Many of these materials have cement-like properties, augmenting the strength and density of the finished concrete.
