Leveraging its admixture technologies and its growing range of value-added products, CHRYSO Southern Africa is helping its readymix customers expand their markets despite the flat conditions in the construction sector.

According to Deon Klopper, sales manager readymix segment at CHRYSO Southern Africa, the slow economy continues to pressurise readymix suppliers, but the answer lies in offering end-users more options to reduce their costs while delivering quality results.

“This is where the role of CHRYSO’s research and development efforts – leading to ongoing technology advances – is becoming so important to the readymix sector,” says Klopper. “Working closely with both the readymix supplier and the end-user, we ensure that we understand what both parties require.”

This allows CHRYSO to share information with end-users about a range of cost effective options, which they then purchase through the readymix supplier.

“End-users need to produce their concrete at a certain optimum cost per cubic metre to remain competitive, while retaining the required quality,” he says. “At the same time, readymix producers can use our value-added products to help grow their markets by offering more solutions to the end-user.”

CHRYSO Southern Africa has continued to expand its range to include technologies such as fibres, mould release oils, curing compounds, decorative concrete, permeability reduced watertight concrete and dust suppressants.

“While the readymix supplier was in the past expected just to deliver what the customer ordered, they can now offer their customers more, by servicing other site requirements and make useful cost saving proposals,” he says.

Among CHRYSO’s admixture developments, for instance, is CHRYSO® QUAD 20, which allows end-users to utilise lower grade sand, where sand and aggregate quality has become more variable. CHRYSO® Quad 20 is a unique formulation which increases the viscosity of cement paste with limited impact on concrete slump and slump flow.

He also highlights CHRYSO’s focus on providing fit-for-purpose solutions that suit the specific priorities of any given project.

“We ask customers what is most important in each of their projects – such as the concrete’s strength, slump or open time – and can then manufacture an admixture specifically for their readymix concrete,” says Klopper. “Our CHRYSO® Optima 1000 technology, for instance, represents a formula that adjusts to match customers’ demands, with unprecedented flexibility for maximum robustness, reliability and precision. It offers up to seven hour workability retention and up to 50% water reduction for an optimal dosage per cubic metre.”


The readymix sector faces a plethora of different demands daily for concrete applications, and CHRYSO Southern Africa has the solutions to ensure that every delivery meets the customer’s requirements.

Common issues such as durability of concrete due to shrinkage cracking can be addressed by CHRYSO products that reduce early and long term drying shrinkage, while the CHRYSO™ Fluid Optima range combats the effect that shrinkage-reduced admixture may have on the strength of the concrete.

Pumping concrete over long horizontal or vertical distances brings the danger of concrete stiffening in the line which can disrupt the pumping operation. CHRYSO’s product ranges can modify concrete rheology to provide the required lubrication within the pump line, reducing pump pressures and improved concrete flowability and providing better workability retention for long pumping distances.

For concrete mortars, CHRYSO admixtures can improve plasticity, cohesion and adherence, and prevent infiltration of water, plastic shrinkage cracking, and the segregation of fine cement and sand particles. Shotcreting is another common application that can be enhanced by the right concrete; available solutions include fibres for cohesive mix to limit rebound and shotcrete accelerators to improve build-up.

Fibre reinforced concrete is ideal for limiting the formation of cracks and for improving surface quality; it can even provide an alternative to mesh reinforcement. Superplasticisers are part of the offering, as fibres tend to reduce the workability of fresh concrete.

Impermeable concrete for waterproof or underwater applications can be achieved by CHRYSO products that reduce water content and water-cement ratios, as well as admixtures that block pores in concrete. In situations where vibration is not possible to compact concrete, self-compacting concrete is the answer and the correct CHRYSO product will allow high fluidity, ease of placing and finishing, with extended slump retention if required

CHRYSO’s extensive range of solutions is based on leading-edge R&D, and can be produced in 26 facilities worldwide, each equipped with sophisticated technology for precision manufacturing.
