6 Prehydration of reactive component i.e. clinker/cement. In case of prehydration of clinker/cement, not only the strength is negatively affected; but the setting time is also delayed. An increase of 0.1% LOI due to prehydration results in a cement strength decrease of 1.0 MPa (1 day) and 1.7 MPa (28 days) [1].

Difference Between Clinker and Cement

Whereas the U.S. standard for portland cement allows for up to 5% of clinker to be replaced by limestone, the standard for blended cement allows for 5% to 15% limestone replacement in PLC (Type IL). The same clinker is used to make portland cement and portland-limestone cement, but there is less of it in PLC.

clinker factor

 · Re: clinker factor. The majority of Portland cement clinker manufactured around the world has a lime saturation of between 90 and . This means that c.1.55 tonnes of raw mix are required and c.0.55 tonnes of CO2 are lost due to calcination of the CaCO3 in the raw material. The clinker factor is therefore 0.65 x the amount of raw mix.

 · A low water to cement ratio is the number one issue effecting concrete quality. The ratio is calculated by dividing the water in one cubic yard of the mix ( in pounds) by the cement in the in the mix (in pounds). So if one cubic yard of the mix has 235 pounds of water and 470 pounds of cement- the mix is a .50 water to cement ratio.

Limestone and clinker — Geometrica

Cement plants need large, column free buildings for limestone blending, fuel and additives storage, clinker storage and palletizing areas. Geometrica provides cost effective buildings for all these needs with quick construction and low labor requirements. Limestone blending beds typically go from under 70m to over 120m.

Understanding Limestone in Cement

 · The change is that the specification adds up to 5% limestone. The biggest difference in production is that the limestone is added to the clinker blend before grinding. Because the limestone is softer than the clinker it will grind preferentially, resulting in a cement with a better particle size distribution with less energy. The limestone also ...

Clinker: compositional parameters

Lime Saturation Factor (LSF) The Lime Saturation Factor is a ratio of CaO to the other three main oxides. Applied to clinker, it is calculated as: LSF=CaO/ (2.8SiO 2 + 1.2Al 2 O 3 + 0.65Fe 2 O 3) Often, this is referred to as a percentage and therefore multiplied by 100. The LSF controls the ratio of alite to belite in the clinker.
