Cementol Delta EKSTRA W can delay the initial hydration of cement (depending on the dosage) without substantially modifying the hardening process, so that an increase in strength is obtained in proportion to the reduction of mixing water.

The latter varies between 5 to 10 % depending on the dosage of Cementol Delta EKSTRA W. Increased workability and easier placeability is achieved by adding Cementol Delta EKSTRA W without lowering the water-cement ratio.
