Cement additives are materials added to cement for the optimization of the cement properties and the cement grinding process. Cement additives are classified into different product groups such as grinding aids, strength enhancers and performance enhancers.   

Why Use Cement Additives?

Grinding of the finished cement in a ball mill

Cement additives are widley used because they: 

  • Improve the efficiency of the cement grinding process
  • Enhance cement properties such as strength development, flowability, and durability
  • Enable consistent cement quality aligned with industry standards and customer requirements
  • Increase cement plant productivity and profitability
  • Reduce energy consumption and support lower CO₂ emissions

 

Sika’s Cement Additives Technologies

Each individual cement plant has different characteristics of local raw materials, availability of possible clinker replacements (such as supplementary cementitious materials - SCM) and varying conditions during the cement grinding process.

In addition, local standards and customers’ needs regarding cement performance vary due to unique climate and construction methods. Therefore, the solution for highest possible production rates or maximized use of supplementary cementitious materials needs to be adjusted individually.

Sika offers a complrehensive range of cement additives designed to:

  • Improve cement performance
  • Increase mill output
  • Support the use of SCM's
  • Meet local market and regulatory requirements

 

Grinding Aids

Grinding Aids are used in the cement mills, including ball mills, verrtical roller mills and HoroMills. 

They are designed to: 

  • Increase mill productivity
  • Reducde electrial energy consumption
  • Improve cement fineness and flowability
  • Prevent praticle agglomeration

Sika’s advanced grinding aid technologies, including polymer-based solutions, enhance the performance of traditional grinding aids and deliver improved efficiency and cement quality.

 

Strength Enhancer

Strength enhancers improve the mechanical performance of cement through chemical activation, without altering particle size distribution.

These additives:

  • Increase compressive strength at early and/or later stages
  • Enhance overall cement performance
  • Improve grinding efficiency when combined with grinding aids
Performance Enhancer

Performance enhancers support the use of supplementary cementitious materials (SCMs) such as slag, fly ash, and pozzolans.

They help to:

  • Maintain or improve strength development
  • Enhance workability and durability
  • Offset potential performance reductions caused by clinker replacement
  • Enable more sustainable, lower-CO₂ cement production
