Grade of concrete is denoted by prefixing M to the desired strength in MPa. For example, for a grade of concrete with 20 MPa strength, it will be denoted by M20, where M stands for Mix. These grade of concrete is converted into various mix proportions. For example, for M20 concrete, mix proportion will be 1::3 for cement:sand:coarse aggregates.
Mar 26, 2020 · The present work reviews the various mineral admixtures used in concrete which modifies the concrete properties. In this study, cement is partially or completely replaced by different mineral admixtures such as fly ash, silica fume, rice husk ash, Ground Granulated Blast Furnace Slag, palm oil fuel ash and metakaolin. The strength obtained is different for different mineral admixtures .
