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.
