SikaGrind®-3251 Activator PK

Strength Enhancer And Grindıng Aid

SikaGrind®-3251 Activator PK is a new generation strength enhancer and grinding aid for cement production completely chloride free. The use of this admixture allows to increase the strength of cement at all the seasoning. This new type of admixture was studied to face the increasing demanding needs due to the new European regulations on cement and to the new quality standards emerging from a more and more competitive market. SikaGrind®-3251 Activator PK is a product with a low dosage that allows to reduce considerably the costs of transport. This product is particularly suitable for cement type I or II to the limestone but is effective also on slag and fly ash cements. The constant increase of compressive strengths at early and long seasoning allows to reduce the clinker ratio in the cement, with a significant reduction of the production cost.

SikaGrind®-3251 Activator PKimproves the efficiency of grinding plants, working as a dispersing agent of electrostatic charges on cement grains that cause agglomeration and plugging. It improves furthermore the mechanical strength, working as a catalyst of cement hydration processes. It is possible to obtain:
  • Higher mechanical strengths particularly at early and late seasoning.
  • Lower cement production cost, thanks to clinker savings.
  • The increase of the whole range of mechanical strength allows to achieve a lower Blaine Specific Surface (SSB), keeping constant the cement properties.
  • Higher efficiency of the grinding system and cost saving as kWh/ton.
  • Higher flowability in mortar and concrete
