FORCE 10,000® D

Performance

Force 10,000 D improves concrete through two mechanisms. The extremely fine microsilica particles are able to fill the microscopic voids between the cement particles, creating a less permeable structure. In addition, the microsilica reacts with the free calcium hydroxide within the concrete to form additional calcium silicate hydrate (glue), producing a tighter paste-to-aggregate bond. Force 10,000 D does not affect concrete set times.

Force 10,000 D will improve the mechanical properties of concrete. In order to meet specified concrete performance levels, however, many variables are involved. These include, but are not limited to; concrete materials, weather conditions, testing techniques and mixing, transporting, placing and finishing practices. ACI and ASTM guidelines must be strictly adhered to.

Addition Rates

Force 10,000 D dosage rates will vary based on the requirements of the application. Dosage rates should be calculated on percent microsilica by weight of cement, or on lb/yd³ (kg/m³) of concrete, as appropriate. Dosage rates will be as specified. If not specified, consult your GCP Applied Technologies representative for your particular job needs.

Compatibility with Other Admixtures and Batch Sequencing

Force 10,000 D is compatible with all conventional water reducers, superplasticizers, set retarders and DCI® corrosion inhibitor. Any air-entraining agent which works effectively with superplasticizers and microsilica, particularly vinsol resins such as DARAVAIR® by GCP Applied Technologies, are recommended. Only non-chloride set accelerators, such as POLARSET® , may be used with Force 10,000 D concrete. All admixtures must be added separately to assure their prescribed performance. Trial mixes and pretesting of concrete are recommended to optimize dosage rates, and ensure ultimate performance.

Force 10,000 D can be used in either central or transit mix concrete production. Force 10,000 D may be used in conjunction with waterreducing admixtures (both normal and high-range as approved by ASTM) to assure workability of the mix.

Packaging & Handling

Force 10,000 D is available in bulk, and 25 lbs (11.4 kg) CONCRETE READY BAGS™.

Dispensing Equipment

Bulk Force 10,000 D may be stored in already existing cement silos. The silos must be completely clean with no foreign residue remaining which may cause contamination. Up-pipes to the silo for unloading bulk tankers should also be clean and clear of obstructions. Small diameter 4 in. (100 mm) rigid metal pipes with several angles (especially right angles) will cause longer unloading times. Large diameter 6 in. (150 mm) flat lined, flexible rubber pipes will allow for the least unloading time. Dispensing bulk Force 10,000 D will take place in the same manner as that used for cement. Augering or dropping from the silo to the weigh hopper is the usual practice.

Storage

Bagged Force 10,000 D should be stored in a dry, protected area. Manual dispensing by tearing the bags is the normal method. A dust mask should be used when dispensing the bagged product, consult the product MSDS for more complete instructions.
