Normal microsilica gel with technical and economic aspects

partoGEL 209 is an advanced type of concrete admixture based on silica fume and super-water reducers, which in addition to strengthening the rheological properties of fresh concrete, increases the compressive strength and reduces the water absorption of hardened concrete.

application

partoGEL 209, in addition to the relative improvement of compressive, tensile and flexural strength, is used to make strong, sealable, impermeable concretes, as well as in places exposed to destructive agents such as sulfate ions and chlorine ions.

advantages

Significant reduction in concrete permeability Increasing concrete density as well as long-term durability of concrete Improving the properties of concrete and reducing the alkalinity of concrete Reduction of water to cement ratio and 15 to 35% increase in compressive strength of concrete compared to concrete samples without additives Increasing the flow and efficiency of fresh concrete Improved pumpability and concrete polishing Reducing permeability, increase compaction and long-term durability of concrete ۱۰ to 15% reduction in cement consumption

packaging

PL209 is available in 25 kg buckets.

Typical properties

physical state Concentrated slurry color dark grey special weight @ 25°C ۱.۳۹ – ۱.۴۹ pH ۵.۰ – ۷.۰ chloride ion no * The mentioned data are obtained based on the latest controlled laboratory tests.

Standards

Although no specific standard has been defined for this product, this product can be evaluated based on the following standards. ASTM C 494, EN 934, ISIRI 2930

application guidline

The recommended dose of this product is 2 to 9% by weight of cement. It is possible to change the consumption dose from the specified range for projects with special workshop conditions, only with the permission of Partak concrete technology experts.

mixing

The best way to use it is to add PL209 after all the concrete components have been added, that is, when the concrete is completely produced, the mix is complete and the concrete is pasty. It is better to add this product to the mixture at the project site. Avoid adding material directly to cement and dry materials. PL209 is compatible with all types of Portland cement and slag. in the case of using some additives, be sure to contact Partak Concrete Technology.

storage and shelf life

PL209 Store in a closed container, away from direct sunlight and freezing conditions. If the above conditions are met, the useful life of the product is 12 months from the date of production.

health and safety

there is not need for special actions but for observing safty actions, it is better to use protection gloves and eye glasses. In case of direct contact with skin or eyes, rinse immediately with water and see a doctor. Please refer to the Safety Data Sheet (MSDS).
