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.
mineral admixtures shall also be considered in water-cement ratio calculations in accordance with Table 5 of IS 456. 4.1.1 The free water-cementratio selected according to 4.1 should be checked against the limiting water cement ratio for the requirements of durability and the lower of the two values adopted. 4.2 Selection ofWaterContent

physical properties of the cement, the curing conditions and the water/cement ratio. Soundness: • Soundness is a physical property of cement paste, which determines the ability of the cement paste to retain its volume after setting is completed. • The unsoundness is due to the presence of free CaO (lime) and free MgO (magnesia) in cement.
