The CHRYSO EnviroMix range of admixtures allows for reduced environmental impact from concrete mix designs
A new range of admixtures aims to support South African contractors to reduce their carbon footprint.
A key feature of the admixture range is that it allows for better utilisation of mixes that incorporate high volumes of pozzolans such as fly ash. CHRYSO asserts that its EnviroMix range of tailor-made admixtures is able to achieve this while still ensuring superior levels of technical performance.
The company’s EnviroMix is said to deliver a reduction in carbon dioxide emissions of up to 50%, while its EnviroMix ULC (Ultra Low-Carbon) can achieve reductions of more than 50% in the carbon footprint of concrete. In addition, it also promises an improved quality of concrete as a result of a lower water-cement ratio for a given workability and increased early and ultimate compressive and flexural strengths.
As part of its offering, CHRYSO also supplies customers with dedicated services such as EnviroMix Impact, which allows the environmental impact of a concrete mix design to be calculated, so that a formulation strategy can be set up for customers to meet specific carbon-reduction targets. The company also offers a digital solution for real-time monitoring of its Maturix concretes, which provides on-site concrete temperature, strength and maturity, humidity and climate monitoring.
The EnviroMix range is said to provide superior finishability, while improving surface quality and reducing cracking potential and also providing better workability and pumpability of concrete, as well as ease of placement and consolidation.
CHRYSO asserts that it continues to strengthen its expertise in the field of concrete admixtures with low-carbon impact and that its solutions are based on numerous scientific collaborations and industrial partnerships, reinforcing its expertise in these new binders including geopolymers and calcined clay cements.
