Microsilica gel with the aim of reducing plastic cracks and improving tensile and flexural strengths
partoGEL 308 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.
partoGEL 308, in addition to the relative improvement of compressive, tensile and flexural strength, is used to make strong, sealing, impermeable concretes, as well as in places exposed to destructive agents such as sulfate ions and chlorine ions. This product is highly recommended for high-traffic surfaces (subject to wear) and thin concrete sections, bulk concretes and high-density concrete sections, precast concrete parts, as well as concrete structures exposed to dynamic loads, impact and fatigue.
Significant reduction in concrete permeability Increase 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 20 to 40% increase in compressive strength of concrete compared to concrete samples without additives Increase the flow and efficiency of fresh concrete Improved pumpability and concrete polishing Reduce permeability, increase compaction and long-term durability of concrete ۱۰ to 15% reduction in cement cement consumption
partoGEL 308 is available in 25 kg buckets.

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
The recommended dose of this product is 3 to 8% 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.
The best way to use it is to add partoGEL 308 after all the concrete components have been added, ie when the concrete is completely produced, the mix is complete and the concrete is in a pasty state. It is better to add this product to the mixture at the project site. Avoid adding material directly to cement and dry materials. partoGEL 308 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
partoGEL 308 is maintaned in closed packaging and away from direct rays of sun and ice situation. in the case of above situation, 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).
