FARCOMENT 1000 is a ready to use, synthetically set-retarding liquid admixture with low plasticizing effect.
FARCOMENT 1000 facilitates placing and finishing by providing controlled retardation of the concrete and mortars setting time, preventing premature stiffening.
Mechanism of Action
FARCOMENT 1000 is used to slow down the reaction between cement and water by affecting the growth of the hydration products and reducing the rate of water penetration to the cement particles.
In addition to the amount of retarder, the setting time depends on type of cement, W/C ratio and
temperature. Cements with low C3A and alkali content are easier to retard compared to cement with large amounts of these constituents. One explanation is that at lower C3A contents, smaller amounts of retarder are adsorbed, leaving larger amounts of the admixture to affect and retard the hydration of the C3S component.
FARCOMENT 1000 complies with:
ASTM C 494 Type B
EN 934-2 – Table 8
ISIRI 2930 – Table 9
Test performed in accordance with the standard method EN 196-1, EN 196-3.

Hot wither concreting
Long travel distance
FARCOMENT 1000 as a set retarding admixture is used primarily to offset the accelerating effect of cement at high ambient temperature and to keep concrete workable during the entire placing period thereby eliminating form – deflection cracks.
FARCOMENT 1000 also is used to keep concrete workable long enough so that succeeding lifts can be placed without development of cold joints or discontinuities in the structural unit.

Method of Use
FARCOMENT 1000 is supplied ready for use and is completely miscible in water.
It can be added in to the mixer at the same time
as the mixing water.
It should not be added directly to the cement or
FARCOMENT 1000 may be added at the end of mixing process by dispensing equipment or it may also be added to the concrete in a drum of ready mix truck, it should be mixed at least 1 minute per m³ of concrete at high speed.
FARCOMENT 1000 is normally dosed at a rate of 0.2 – 0.6% by weight of CM.
Higher dosages maybe utilized for special conditions and applications.
Dosage recommendations depend on the characteristics of the mix design.
Field testing is recommended to determine optimum dosage and effects on both plastic and hardened concrete properties, such as: workability and workability retention, setting time, early and ultimate strength.
Other product info
FARCOMENT 1000 is suitable for use with cement replacement materials e.g. Fly ash, silica fume and blast furnace slag cement concrete.
With other Admixtures
FARCOMENT 1000 should not be premixed or used with other admixtures unless receive the approval from manufacturer.
We would recommend that SHIMISAKHTEMAN be consulted in such circumstance.
FARCOMENT 1000 is supplied in 20kg gallons and 250kg drums.
Storage is recommended to keep within the range of 5°c to 40°c. If product has frozen, thaw and agitate until completely reconstituted.
Keep out of direct sunlight.
12 month when FARCOMENT 1000 is kept under the recommended conditions and stored in unopened and undamaged original sealed containers.
Safety and Handling Precautions
FARCOMENT 1000 is a low- hazard substance it does not irritate skin and retina under normal conditions. But in the line with general hand ling precautions to avoid contact with skin or eyes, protective gloves and goggles should be worn.
