White cement | Cementir Holding N.V
White cement production process STAGE 1 – RAW MATERIALS PRODUCTION & PREPARATION Mining or sourcing strictly selected raw materials ( to guarantee desired clinker/cement whiteness ) to produce a suitable dry powder called raw meal composed of defined proportions of Calcium (C), Silica (S), Alumina (A) to feed the kiln.
Mineral Additive in the Production of New Cement Types
quarry dust acts as ﬁller, reacting with the products of cement hydration to form calcium bicarbonate. Basalt quarry dust is not only ﬁller, but also a pozzolanic additive. When hydrated in a mixed cement composition, it leads to the formation of an additional amount of calcium hydrosilicates C–S–H, which

Cementitious. Supplementary cementitious materials (SCM’s) are minerals used in varying proportions during the last phase of the cement production process. SCM’s make it possible to obtain a range of cements with different properties. They can be:
gypsum as an additive to cement
Brick powders as pozzolanic additives Cement . A large number of studies are available on the use of brick powder as an additive in cement production. In many cases these were designed in such a way that only a selected brick powder was added to the cement in different proportions.
What is the difference between grey and white cement? - Quora
White cement is stronger (harder), more cohesive, sticky, durable. Not easy to be scratched by mechanical drags. White cement produces thinner tile, forms projected (protruded) object, fills smaller holes/gaps, covers pored surface. When using the same tools, the finished wide surface is smoother (almost like glass), thus easier to clean.

EP0121059A2 - Process for manufacturing white cement - Google
The invention relates to a method for producing white cement, in which the reducing atmosphere is maintained over the entire length of the rotary kiln and the raw material is pre-calcined in the preheater with the addition of additional fuel and combustion of the CO contained in the kiln exhaust gases.
What is Cement Clinker? Composition, Types & Uses - Civil
Energy efficiency improves and the electricity costs for the manufacturing process are about 15% lower as well. Use of Clinker: Conversion to Cement. Clinker, combined with additives and ground into a fine powder, is used as a binder in cement products. Different substances are added to achieve specific properties in the produced cement.
