Few chemical parameter known as moduli values responsible for producing clinker on firing.
When the raw materials available make it hard to achieve burnability goals, the use of fluxes and/or mineralizers may be helpful. Fluxes and mineralizers indirectly affect burnability by promoting clinker phase formation to occur earlier; their effect on clinker formation and cement quality is briefly described.
Raw mixes with 4%, 7%, and 10% phosphogypsum were prepared to determine the technological feasibility of utilizing phosphogypsum and its desirable quantity in the raw mixes. The raw mixes were prepared from ordinary raw materials (Table 1).
