Advantages

High resistance to environmental impacts
Low hydration heat
Low carbon emission
High workability on ready-mix concrete

Recommended Applications

Ready – Mix Concrete

Suitable for ready-mixed concrete productions where early strength is not critical and strength at 28 days or more is important.

Environmental Impacts

Suitable for waste water treatment plant projects, industrial ground concrete which is exposed to sulfate attack, concrete to be made for construction of dam and water channels.

Mass Concrete

Suitable for use in mass concretes requiring low hydration heat. It prevents formation of thermal cracks.

Ground Injection Projects

Suitable for ground improvement projects with its high blaine and high resistance to sulfate.

Availability and Delivery

Bulk

Precautions in Application

Follow the standard minimum cement content and maximum water/cement ratio.
Provide adequate protection and cure according to correspondent standards.
Keep framework and scaffolding in place until adequate mechanical strength is obtained.
Ready-mix concrete: avoid long time transportation.
Measures should be taken to prevent crack formation in concrete casting in hot and windy weather.

Not Recommended for

Delay in setting time and lower early strength may be obtained when used with a high amount of mineral additives (ground granulated blast furnace slag, fly ash, etc.)
Not suitable for concrete production to be poured without any measures under cold weather conditions.

Environment, Safety and Storage

Wear suitable protective clothing, gloves, eye and face protection equipment.
For detailed safety information, request the“Safety Data Sheet” of the product.
Stock the bulk cements in suitable silos so that they are not exposed to moisture and wind, and the bag cements are stacked in a maximum of 10 rows in the warehouses protected from moisture, wind and cold.
