Cement Additives are a Popular Choice Because They...
- Positively affect the production process and the quality of cement.
- Improve defined cement properties, e.g. powder flowability, strength development, mortar workability and durability.
- Adjust the cement quality to meet the demands set by relevant standards and cement customers.
- Contribute to the profitability of cement plants.
- Ensure less environmental impact by reducing utilization of energy and resources combined with minimized carbon footprint.
Sika’s Cement Additives Technologies
Each individual cement plant has different characteristics of local raw materials, availability of possible clinker replacements (such as supplementary cementing 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 many types of cement additives known to improve cement quality, increase production efficiency and meet your local demands:
Clinker is often replaced with supplementary cementitious materials (SCM) such as granulated blast furnace slag, natural pozzolanes and fly ash in order to reduce CO2 emissions and material cost. However, SCM may counteract strength development, powder flowability, mortar workability and durability, which are critical for cement quality.
- Enhance early and/or final strength, which allows for higher clinker replacements and hence less CO2 emission.
SikaGrind® 200 Series
Grinding Aids are used in the cement mill (Ball Mill, Vertical Roller Mill, HoroMill) to increase the productivity, save electrical energy and/or to increase the fineness and improve defined cement properties, e.g. powder flowability.
- Achieve a constant cement production at a higher output (Tons/hour)
- Reduce the Specific Energy Consumption (kWh/Ton cement)
SikaGrind® 700 Series
- Adjusting cement powder flowability
- Suppress carbon bleeding
- Improve concrete workability
- Air entrainment for masonry cement
SikaGrind® 800 Series

Sika’s Technical Services for Cement Specialists
Understand local situations and define targets
Whether being confronted with a special problem or in the daily challenge to improve profitability, Sika will assist you in reaching your targets. Local conditions and demands vary strongly, making it necessary to handle every plant individually. Sika can offer tailor-made solutions, designed to meet individual challenges, thereby working together as partners with one joint target.
Evaluation of cement quality in laboratory analysis
In case of inconclusive results or the need for further optimization work, another plant trial cycle with potential product modification and laboratory pre-trials may be necessary. Sika's analytical laboratory is well-equipped with modern instruments and well-trained technicians.
Laboratory pre-trials to evaluate trends
To begin the product and process optimization, well-defined and technically feasible targets related to the present production and quality parameters are agreed upon. Based on our experience in cement production process and product know-how, one or two SikaGrind® products are recommended for plant trials. If necessary, laboratory pre-trials can be arranged in one of Sika's regional cement laboratories.
CO2 Emissions
In case of inconclusive results or the need for further optimization work, another plant trial cycle with potential product modification and laboratory pre-trials may be necessary. Sika's analytical laboratory is well-equipped with modern instruments and well-trained technicians.
Execution of plant trials by Sika experts
Preparation and execution of plant trials are handled by Sika staff in cooperation with plant staff. The production data and cement analysis results determined in specialized laboratories are then discussed between you and Sika’s cement specialists, to agree upon the target fulfillment and define next steps.
