MasterCem LS 3735 - Cement additive engineered for enhancement of cement late strength and reduction of unit grinding energy / increase of cement mill throughput
What is MasterCem LS 3735?
MasterCem LS 3735 is a liquid, ready-to-use
cement additive designed to enhance cement
performance. In addition to acting as a Grinding
Aid in the milling process and a flow aid in
cement conveyance, MasterCem LS 3735
improves specific cement properties by the
activity of its chemical components. These act in
the modification of clinker characteristics and in
the enhancement of its hydraulic properties.
Products of the MasterCem LS 3000 series are
specifically designed to increase late strength of
cement. These benefits can be used either for
achieving superior product performance or for
cement optimization while maintaining the
original performance level. Typical late strength
improvement is +5-15% at 28 days vs. plain
control. However, product performance is
dependent on grinding equipment
characteristics, process conditions, raw material
properties and cement type. To best benefit from
cement additives, mill and separator process
parameters may need to be adapted.
MasterCem LS 3735 improves the flow
characteristics of cement with positive impact on
cement conveyance and reduction of pack-set in
What is MasterCem LS 3735 used for?
MasterCem LS 3735 is developed for
application in the cement grinding process in:
• Ball mills (closed and open circuits)
• Vertical mills
• Other grinding systems, such as: GGBS
What are the benefits of MasterCem LS 3735?
MasterCem LS 3735 offers the following benefits
to cement producers:
• Cost reduction due to lower unit
grinding energy (kWh/t) and
optimization of cement fineness and
com-position while maintaining cement
• Capacity extension due to higher mill
throughput and optimized cement
• Sustainability due to reduced clinker factor
and spe-cific CO2 emissions. Gain of carbon
• Product differentiation due to enhanced
cement performance and improved properties
for the final application.
• Improved cement handling due to faster
cement conveyance through the plant and in
the distribution logistics. Reduction of plant
stops and optimized storage in silos.
