>CLINKER SUBSTITUTION IN THE CEMENT INDUSTRY
Lowering the clinker-to-cement ratio requires the use of Supplementary Cementitious Materials (SCMs). SCMs have been used by the cement sector for a long time.
>Beneficial reuse of dam fine sediments as clinker raw material
Beneficial reuse of fine sediment as a raw material to produce clinker was also investigated by different authors [18], [19], [20]. Aouad et al. [18] worked on a contaminated sediment from a waterway in Northern France. They obtained a satisfying clinker by introducing this sediment with a mass ratio of 39.1 wt%. The product reactivity was ...
>Portland Cement Clinker
Portland cement clinker is made by burning, at least to sintering, a precisely specified mixture of raw materials (raw meal, paste or slurry) containing CaO, SiO 2, Al 2 O 3 and small quantities of other materials. The raw meal, paste or slurry shall be finely divided, intimately mixed and therefore homogeneous.
>Clinker Production
Raw materials for clinker production are for good reasons primarily based on limestone, clay or its natural mixture, marl. In many cases, alternative raw materials are used mostly as corrective materials. Typical examples are given in Table 1 [33]. With respect to resource efficiency along the value chain, concrete recycling is already in an ...
