MC-TORKRETHILFE BE / CENTRAMENT RAPID 640 Chloride Free Guniting Aid / Alkali free Shotcrete Accelerator

MC-Torkrethilfe BE is a chloride free guniting aid in a powder form specifically developed and designed to meet the demand for efficient and multifold properties desired at guniting job sites. MC-Torkrethilfe BE is suitable as an admixture for all sprayed concrete and shotcreting operations. MC-Torkrethilfe BE accelerates the rate of hardening and development of strength. By virtue of its formulation, it waterproofs the mix and renders the sprayed mortars substantially impermeable in addition to plasticizing the mix. MC-Torkrethilfe BE is formulated with carefully selected raw materials in view of making it suitable for use in most of mortar and concrete mixes, in which the use of calcium chloride or similar substances is undesirable.

MC-TorkrethilfeBE accelerates the rate of setting by plasticizing property thereby making the concrete and mortar rode hard enough minutes after spraying. It will seal the water seepages from the ground water in tunnels, galleries, drifts and shafts. It provides high early and final strength, allows overhead guniting aid, provides improved bonding properties, can be used at lower temperatures, allows spraying on moist surfaces; allows thicker layer in single operation and reduces material losses caused by rebound. It has been approved officially (PA VII-5/114 BE) as chloride free guniting aid.

Centrament Rapid 640 is a liquid, alkali-free setting accelerator for shotcrete applied by dry- or wet-spraying. The dosage depends on the concrete- and ambient temperatures, as well as on the desired curing-behaviour and the reactivity of the used cement. Overdosing can lead to delayed curing and reduced early and final strengths.

Product Properties & Areas of Application of Centrament Rapid 640
  • Causes fast setting
  • Little reduction of the final strength
  • Accelerates the work-process by allowing a layer-thickness of 15 to 20 cm per work-step
  • Reduces dust-formation
  • Possible acceleration of concrete with a higher consistency
  • Shotcrete applied by dry- or wet-spraying
  • Stabilization in tunnel construction and mining
  • Temporary rockface-stabilizations
  • Hillside stabilizations
