X-CEM BASE

Chloride-free powder admixture
for cement mixes

Description

X-CEM BASE is a special chloride-free powder admixture consisting of inorganic compounds to be added to cement mixes (slurries, grouts and concrete) to increase performance both in the green and the set state.

The action of X-CEM BASE allows superfluid and non-segregating mixes to be obtained as well as a considerable reduction in the mixing water.

The low water/cement ratio of the cement mixes obtained using X-CEM BASE results in high strength after short as well as long curing, very limited or no shrinkage at all and a very low microporosity.

Usage field

X-CEM BASE is used as an additive or admixture in the preparation of:

  • cement slurries for injection into masonry needing repair;
  • cement slurries injected to anchor steel rods, cables, tie rods, …;
  • grouts with little or no shrinkage for the repair of r.c. structures;
  • superfluid, non-segregating concrete with low water/cement ratio and little or no shrinkage for structural elements in general;
  • concrete for industrial floors without or with a limited number of contraction joints;
  • high-strength concrete also with short curing (24-48 hours);
  • waterproof concrete.

 

Performance of the mixes with added X-CEM BASE depends on the design mix (in particular on the type and proportion of cement, the type of aggregate and the grading curve), casting methods and site conditions as well as on correct engineering/design of the type of work to be carried out.

 

Packaging

Application

Put the X-CEM BASE powder admixture directly into the concrete mixer together with the dry aggregates, using normal personal protective equipment such as gloves, goggles and mask.

 

Total mixing water

  • Cement slurries:

use a total of 30-35 litres of mixing water for every 100 kg of cement + X-CEM BASE

  • Cement grouts and concrete mixes:

X-CEM-BASE reduces the total mixing water by approx. 15–20%, workability being equal.

Average Consumption

6-8 kg X-CEM-BASE per 100 kg cement.

A preliminary test is recommended to decide the best proportioning in relation to the required characteristics and the available materials.
