Advantages

• High strength at an early stage
• Minimum 83% whiteness value
• Stable color tone
• High workability

Recommended Applications

• Thanks to its high fineness, smooth surfaces are obtained.
• Construction Chemicals due to its workability, it is suitable for the production of joint filler, tile adhesive, and various construction chemicals.
• Tiles, Curbstones, and Keystone with its stable color tone, it is suitable for the production of elements such as paving stones, borders and, urban furniture.

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 or air, and ensure the bags of cement are stacked in a maximum of 10 rows in warehouses to protect them from moisture, wind, and the cold.

Precautions regarding use 

• Follow the standard minimum cement content and maximum water/cement ratio.
• Provide adequate protection and cure according to corresponding standards.
• Keep framework and scaffolding in place until adequate mechanical strength is obtained.
• Ready-mix concrete: avoid long transportation time.
• Take measures to prevent crack formation in concrete casting in the event of hot or windy weather.

Not Recommended for

• Production in which high whiteness is required. The desired whiteness may not be obtained when used with aggregates with unsuitable color tones.
