Shotcrete Admixture Products

Shotcrete is concrete that is sprayed at high velocity typically onto a vertical or overhead surface. Shotcrete admixtures improve the properties of shotcrete mixes and help make construction projects more efficient. With the demand for high-quality shotcrete growing, many companies have developed innovative shotcrete admixtures that offer unique benefits and advantages.

Shotcrete Admixture Products by Sika

Some shotcrete admixture products by Sika:

• Sigunit Shotcrete accelerator, available as liquid, powder, or instant powder to develop the highest strength for overhead applications and thick build-ups.
• Sika® ViscoCrete® SC are high-range water-reducing super-plasticizers that improve the workability of concrete and maximize compressive strength.
• SikaTard® is a cement hydration stabilizer that ensures long-term stabilization of the concrete mix, thus enabling optimum shotcreting with high flexibility.
• SikaPump® products improve the pumpability of concrete mixes by reducing friction and wear.
• SikaTell® is a colloidal silica additive that stabilizes concrete by reducing rebound and thereby increasing the long-term durability of shotcrete.
• SikaFiber® are steel or synthetic fibers, added to the shotcrete as it sets, increasing efficiency and resilience.
• SikaFume® is a microsilica additive that significantly improves the adhesion of shotcrete and its durability.
• FlexoDrain is a sub-drainage system that allows for the application of shotcrete in case of moderate water ingress and protects it from aggressive mountain water.
• SikaCare reduces the adhesion of cement mortar and concrete to equipment, extending its use and reducing wear.
• SikaPump® Start-1 lubricant reduces the friction between concrete and hoses/pipes, as well as within pipes during the start-up of pumping.
• SikaShot® is an advanced, highly accelerated spray mortar that can consolidate and pre-seal substrates before shotcrete lining.
