A Safer, High-Performing, and Sustainable Colloidal Silica Shotcrete Additive for Construction Formulators

We work with construction formulators to create customised shotcrete additives for the construction sector.

Say goodbye to carbon-intensive additives and embrace GeoSHOT40 – a sustainably recovered solution that elevates the performance of sprayed concrete applications.

Geo40 has worked with our formulation partners to develop a range of GeoSHOT40 solutions to enhance the overall performance characteristics of sprayed concrete. This sustainable additive can provide several performance advantages to market applicators.

By incorporating small volumes of GeoSHOT40 into in-market shotcrete mix designs, applicators will experience a marked improvement in workability, pumping, and site performance.

The nanoparticles of GeoSHOT40 perform as a lubricant or viscosity-modifying additive, significantly enhancing the fluidity and cohesion of the shotcrete mix.  Improving pumping and spraying, allowing applicators to work more efficiently and effectively.

Not only does GeoSHOT40 enhance workability, but it also delivers exceptional performance in terms of strength, reduced porosity and improved durability. When integrated into the shotcrete mix, the colloidal silica particles react with calcium hydroxide, resulting in the formation of additional cementitious compound sites. These contribute to the development of a denser and more cohesive concrete matrix, which translates into enhanced performance.

GeoSHOT40 goes beyond performance enhancements. It offers superior adhesion properties (less rebound), strengthening the bond between the shotcrete layer and various substrates, including concrete, steel, and rock. The nanoparticles fill microscopic voids, known as the particle-to-particle filling effect, creating a robust and long-lasting connection within the shotcrete.

Additionally, GeoSHOT40 colloidal silica shotcrete additive can improve chemical resistance, protecting your sprayed concrete against aggressive substances and environmental factors.

The benefits of a safer, high-performing, and sustainable shotcrete additive are available with GeoSHOT40. Contact us today to upgrade your in-market sprayed concrete additive solutions today.
