MINERALISED CLINKER AND CEMENT Modern

2019-5-21  This technology has been successfully applied at Aalborg Portland since 1994, with considerable savings in fuel consumption and improvement in cement quality [3]. Mineralised Clinker Although at times used loosely, the term mineralisation in clinker production is defined in the same way as it is in geology, i.e. it is the process of promoting mineral formation.

Portland Cement Clinker - Composition and Hydration

The effects of minor elements on the clinkering process, and on the qualitative and quantitative phase compositions of Portland cement clinker are discussed. The distribution of some minor elements (F, Na, Mg, S, K, Ti, Mn, and Sr) has been investigated, as well as the effects of sulfate and fluoride mineralisation on clinkers from two different production units (Plant 1 and Plant 2).

CO2 mineralisation of Portland cement - Research -

A promising approach is to substitute the traditional hydration of cement by carbonation of cement clinker for the hardening of the material in concrete production. This work is a tailor-made experimental approach to explore the mechanisms of Portland clinker carbonation under wet conditions.

2015-10-15  Calcium fluoride can be used as mineralizer in the manufacturing of Portland cement clinker in order to decrease the temperature of clinkerization and/or increase the alite content of clinker. Also, by-products with fluorides could be valorized as mineralizers, for example by-products of the primary aluminum industry. But it is necessary to evaluate

Clinker - Cembureau

Clinker substitution and novel clinkers. The effort in reducing the amount of clinker in cement is progressing well and the clinker to cement ratio has been reduced to 76,4%. The uncertain sustainable availability of clinker substitutes is the main constraint. CEMBUREAU has projected the clinker to cement ratio at 70% by 2050.

A cement based on the Plant 1-mineralised clinker reacts more slowly during the early hydration than corresponding ordinary clinker, but then accelerates to reach higher reaction rate after 12 h. The cements based on the Plant 2-mineralised clinkers react more slowly than the corresponding ordinary cement [1] .
