SikaGrind®-721 is a chloride-free liquid additive with strength-enhancing properties. SikaGrind®-721 has been specifically developed to obtain cements with strongly increased early and final strength.
SikaGrind®-721 provides the following advantages in the cement production:
- Less accumulation of material on grinding equipment (grinding balls and mill);
- Higher efficienty of the plants (tons per hour) due to reduced grinding time per ton;
- Higher separator efficiency due to improved dispersion;
- Easier achievement of the desired cement fineness;
- Cost savings due to lower power consumption per ton.
SikaGrind®-721 gives the following advantages to the finished cement:
- Increased early and final strength;
- Improved powder flow characteristics and easier discharge of silos.
