Other than lime, the most prominent chemical additive is ordinary Portland cement (OPC) which has been extensively used for somewhere about 100 years (Estabragh et al., 2014; Ma et al., 2018).Portland cement is a fine heterogeneous compound, consisting of four different oxides, such as tricalcium silicate (C 3 S), Di …
Role of additives in the cut off values of RoM limestone: Besides Limestone, cement raw mix requires 8 to 10 per cent additive material like laterite, bauxite, red ochre, iron ore etc. Day-by-day, quality of additives are deteriorating i.e. increase in silica. The quality also deteriorates as we go down the depth.
