Manufactured Sand

Increase % of Manufactured Sand

Acti-Gel® 208 revolutionizes concrete to help concrete producers realize material cost savings on every cubic yard. Our robust additive enables the concrete producer to increase the % of manufactured sand by up to 100%, thereby replacing the natural sands. Benefits of manufactured sand in concrete include consistent air content, improved compaction, and increased density. Acti-Gel® 208 enhances the finishability, workability, and pumpability of the concrete to increase the quality of the mix while saving $/yd3 on every batch.


Acti-Gel® 208 in Concrete Block

Acti-Gel® 208 stabilizes dry cast mixtures, improves paste quality, and provides efficient cement hydration. Acti-Gel® 208 enables a 15% reduction in cement content while maintaining strength, stability, and durability.

Ready Mix

Acti-Gel® 208 in Ready Mix Concrete

Acti-Gel® 208 is a low-dose rheology modifier and anti-settling agent that dramatically improves the performance and paste quality of concretes. By adding a few pounds of Acti-Gel® 208 per yard of concrete, our mineral additive transforms almost any concrete mix into a stable, workable, and consistent concrete.

Acti-Gel® 208 will improve the quality of concrete when optimized into specific concrete formulations. The product can also be used in any mix design to recover the slump of concrete mixes that may be rejected on the job site for no other reason than the slump is above specification.

Acti-Gel® 208 has the ability to pump low-slump lightweight, stabilize high-slump piling grouts, develop creamy paving mixes, and much, much more. Click on the link below to discover how Acti-Gel® 208 can enhance your company’s applications.

Acti-Gel® 208 in Slipform and Extruded Concrete

Acti-Gel® 208 stabilizes the mix to allow a producer to deliver slip-form mix designs that measure a higher slump than ever used before in these applications. Whether slip-form machines are making curbs, pavements, or highway barrier walls, Acti-Gel® 208 will make a four inch slump concrete stand straight on end out of the machine. The result is a creaminess and superior finish that is unparalleled in the current market. Acti-Gel® 208 can eliminate the pains incurred when trying to finish a low-slump extruded mix due to our enhancement of the available cement paste.

The same concept works for hollowcore applications in the prestressed industry. Download the PDF file below to learn more.

Acti-Gel® 208 in Lightweight Concrete

Acti-Gel® 208 benefits lightweight concrete in two distinct ways: pumpability and finishing. Projects notice consistent, improved pumpability even when slumps vary from load to load. Concrete finishing becomes easier as Acti-Gel® 208 provides a slick, creamy concrete for finishers to work. With Acti-Gel® 208 it is possible to pump low slump lightweight concrete when aggregates are not properly conditioned due to extenuating circumstances at the plant.

Elimination of segregation means that in lightweight concrete Acti-Gel® 208 will keep the aggregates contained evenly throughout the plastic mix while providing high-quality cement paste on the surface for enhanced workability.

Acti-Gel® 208 in Pumpable Cementitious Mixtures

Acti-Gel® 208 works in many applications as a pump aid by creating a lower-viscosity lining in the pipe/hose wall to lubricate the mass being pumped. Acti-Gel® 208 thereby increases the pumpability of the mixture while also eliminating segregation of the paste from the water or the paste from the sand. Acti-Gel® 208 works well in grout mixtures that contain low cement contents and helps the grout resist leaking out of the area it is meant to fill.

Acti-Gel® 208 helps prevent settling in the pipe or hose to prevent blockages in the line. When pressure is exerted on the inert Acti-Gel® 208 enhanced mix then it should resume pumping easily. This benefit is excellent for when deliveries are delayed or pumps momentarily malfunction.

Shotcrete Gunite

Acti-Gel® 208 in Shotcrete and Gunite

Acti-Gel® 208 promotes a cohesive concrete that stabilizes nearly the instant energy is removed from the system. This natural phenomenon is perfect for shotcrete and gunite where high lifts, thick walls, and one-pass overhead applications are desired.

Wet mix shotcrete can be dosed with Acti-Gel® 208 at the ready mix plant or on the job site. Our mulchable bags work well in shotcrete and only take a few minutes to break down and disperse the additive. Acti-Gel® 208 will instantly make a stable, pumpable, and cohesive shotcrete mix that will impress the nozzlemen, pump operator, and finisher. Acti-Gel® 208 works well in civil, residential, geotechnical, underground, and architectural shotcrete.

Dry mix gunite can be dosed with Acti-Gel® 208 in pre-packaged cement/sand bags or directly into the auger of a volumetric truck. Our feeder hopper has proven itself time and again to give a reliable dose of Acti-Gel® 208 into the dry mix system for superior performance.

Acti-Gel® 208 in Precast and Pre-Stressed Concrete

Acti-Gel® 208 has the unique ability to stabilize the mix and enhance the quality of the cement paste. With a more robust cement paste, Acti-Gel® 208 delivers a superior off-form finish for nearly every precast/pre-stressed member. Reduced shrinkage, high-early strengths, and elimination of bug holes are just a few of the benefits often noticed when optimizing a mix design with Acti-Gel®.

Acti-Gel® 208 has been used in heated beds and non-heated beds across the world to produce near flawless pieces where it was difficult to get a nice, durable finish. Acti-Gel® 208 works with conventional concrete, dry cast, and self-consolidating concrete (SCC).

Acti-Gel® 208 will help produce precast/pre-stressed concrete that will make a company proud to stamp their name onto it and send it down the road.
