Both standards regulate the properties of Portland cement: Density: medium ( 1000-1300 kg / m3) and true ( 1400-1700). The fineness of the grind depends on the way the clinker is treated and the size of the sieve screens. The lower this indicator, the more high-quality cement is considered. Heat dissipation is a property characteristic of all ...

P.-C. Aïtcin, in Science and Technology of Concrete Admixtures, 2016 3.10 Conclusion. Portland cement is a complex product obtained from unprocessed common natural materials: limestone and clay. Consequently, the characteristics of Portland cement clinker may vary from one cement plant to another. To limit the variations of the technological properties of Portland cement, acceptance standards ...

Portland Cement (PC) is the name given to a cement obtained by intimately mixing together calcareous argillaceous, or other silica, alumina and oxides of iron-bearing materials, burning them a clinkering temperature up to about 1450°C, and grinding the resulting clinker to required fineness. Components of Portland Cement (PC) are as follows ...
