® 2 0 8 Gel Acti - High Performance Rheology Modif ier and Mix Stabilizer Blocks and Pavers Minerals INTERNATIONAL, LLC® Active Integrity. Innovation. Teamwork. Execution. Product Description Acti-Gel® 208 is a low dose rheology modifier that stabilizes mixtures, provides superior compaction, and dramatically improves the performance and paste quality of concrete blocks and pavers. When fully dispersed, Acti-Gel® 208 particles form a unique lattice ‘microstructure’ that supports slightly higher yield stress and thixotropy resulting in a greater ability to stabilize both cement particles and aggregate with reduced deformation. In the block/paver manufacturing process, designs can be optimized to improve the economics of each unit produced. In these mix designs Acti-Gel® 208 will allow an increase in moisture while maintaining shape stability, achieving target strength, and maintaining swipe. Acti-Gel® 208 is made from a highly purified Mg-aluminosilicate using a patented process. It is non-swelling and shear stable in both low and high salt environ- ments and between pH 2-13. Acti-Gel® 208 does not affect set times or air content. Acti-Gel® 208 complies with ASTM C 494, Type S. Packaging Acti-Gel® 208 is available in liquid or powder form. Performance Acti-Gel® 208 is a thixotropic material that improves paste quality, provides more even cement hydration, and dramatically stabilizes concretes. When used in an optimized mix design, Acti-Gel® 208 has been shown to increase green strength, decrease rapid chloride perme- ability, and reduce eflorescence – all with outstanding stability and compaction. Please contact your local representative for recommendations.

    Acti-Gel 208 can be added in the mixing sequence at various stages depending on the application, using a recommend-ed dry dosage of ~2.5 lbs. per yd3 or ~1 gallon per yd3. Please contact your local representative for recommendations and to schedule a free on-site plant trial.

    Guidelines for Use

    Product Data Sheet, Rev. January 2017Recommendations and advice concerning dosages, application, performance, and use is provided in good faith, based on our testing, experience, and knowledge of the product under normal conditions. All claims based on performance are believed to be accurate. No guarantee, either expressed or implied, is made with reference to the infringement of any patent. These values represent typical data from samples taken from production batches. They are not considered to be speci-cations. Results may vary depending upon equipment and procedures. The user of these materials is responsible for determining its suitability for theirapplication with dierent materials and actual site conditions.

    The performance of Acti-Gel 208 is dependent on mix proportions, local materials, cement chemistry, neness of mate-rials, and w/c ratio. Potential mix designs for specic applications should be evaluated using actual project materials to ensure that the chosen mix design meets project specications. Please contact your local representative for recommendations.
