SHOTCRETE APPLICATION

Over the years, CHRYSO has developed a large expertise regarding the mix design, the dedicated technologies and the technical support necessary to achieve optimal shotcrete concrete performances throughout the project completion.

A large range of shotcrete accelerators

CHRYSO offers a complete range of accelerators adapted to your building site constraints.

„ Low rebound rates

„ Compatibility with almost all spraying equipments

„ Fast strengths gain

Alkali-free accelerators are easy and safer to use. Our accelerator range is compatible with all cements, they operate perfectly in synergy with CHRYSO®’s superplasticizers or plasticizers to provide very high early compressive strengths.

CHRYSO Superplasticizers

CHRYSO superplasticizers are designed to enhance the rheology of shotcrete and in particular, long workability retention.

CHRYSO®Optima 100 and CHRYSO®Optima 1000 ranges are especially suited for shotcrete applications:

„ Allowing concrete transportation over long distances and flexibility regarding waiting time on site

„ Maintaining an excellent pumpability even when using fibres reinforced concrete

„ Ensuring a very good cohesion of the concrete

„ Enabling very high early compressive strengths

CHRYSO Fibres offer

Structural renforcement with macro fibres

Combined with CHRYSO®Jet range of admixtures and our dedicated concrete mix-design know-how, synthetic fibres ensure a flawless and successful operation throughout the project. Fibres dedicated to spray concrete are designed for:

„ Easy pumping

„ Maximum rebound reduction

„ Ultimate tensile strengths performance

„ Enhanced durability

As a part of its complete range of tunneling solutions, CHRYSO dedicated macro-fibres allow to meet the requirements of classes A, B and C shotcrete (EFNARC or ASTM standards).
