FAST FLUID® 300

Flow Improver Additive
and Drying Accelerator
for Cementitious Screeds
Chlorides Free

Description

FAST FLUID 300 is a liquid additive for cementitious screeds with a fluidifying, water reducing and drying accelerating action.

FAST FLUID 300 is specifically designed to reduce the amount of the mixing water and to anticipate the partial development of the heat of cement hydration. The result of this synergy is a significant reduction of the screed drying time,  that allows an earlier use of the area for the laying of subsequent coatings.

FAST FLUID 300 is chlorides free.

FAST FLUID 300 is not suitable for the activation of cement mortars and concretes.

The bar-graph below (figure 1) shows a comparison between the trends over time (*) of the moisture content percentage, measured with the standard calcium carbide method, of a normal sand / cement without admixture screed and a similar system, prepared with FAST FLUID 300 (**):

*: Average Curing Conditions: T = +5°C, UR % = 50;

** Percentage of FAST FLUID 300 in the Screed = 1.5% by weight compared to cement.

 

The line graph diagram in Fig. 2 compares the hydration curves (obtained under adiabatic conditions) of cement pastes (ratio water / cement = 0.4) and highlights the above mentioned anticipating effect.

Usage field

FAST FLUID 300 is used in the preparation of:

  • conventional cementitious screeds both anchored and floating;
  • composite and light-weight floating and anchored screeds;
  • screeds for underfloor heating systems: FAST FLUID 300 fluidifying action increases the workability of the mixture, making possible the realization of a very compact screed with reduced air content and of improved thermal conductivity properties. The optimal FAST FLUID 300 dosage, to realize sand / cement screeds on underfloor heating systems is 1.5 kg each 100 kg of cement.

 

Advantages

The benefits of using FAST FLUID 300 are:

  • reduction in screeds drying time;
  • mixing water reduction (even up to 20%);
  • fluidifying action;
  • hygrometric shrinkage reduction;
  • workability increase;
  • increase in all mechanical strengths.


Combination with FAST FLUID AG

FAST FLUID 300, in combination with FAST FLUID AG, allows the realization of screeds at temperatures down to 0 ° C.

The bar- graph in Fig. 3 compares the development of compressive strength of sand / concrete screeds after 3 curing days*:

Application

FAST FLUID 300 is ready to use and is poured into the kneading (or in the mixer) as last component after adding the mixing water.

Dosage

FAST FLUID 300 is generally used with doses ranging from 1 to 2% by weight compared to cement (1.1 - 2.2 liters each 100 kg of cement).

When fabricating screeds at temperatures down to 0 ° C using the combination FAST FLUID 300 + FAST FLUID AG, the best performance is achieved at the following dosages:

  • FAST FLUID 300 = 1.5% by weight compared to cement (equal to 1.65 litres each 100 kg of cement);
  • FAST FLUID AG = 1.5% by weight compared to cement (equal to 1.00 litres each 100 kg of cement).
