The parent company of Texas-based Chryso Inc. has announced a global range of admixture products and companion services aimed at controlling the carbon footprint of ready mixed and precast concrete. Paired with supplementary cementitious materials, EnviroMix agents enable carbon dioxide emissions reduction up to 50 percent when measured against conventional concrete mix designs, while EnviroMix ULC (Ultra Low-Carbon) agents match that metric and impart high performance properties in finished slabs, structures or elements. 

Products adapted to the specific performance requirements of ready mixed or precast concrete will be deployed to support Chryso customers in the evolution of construction methods. Producers or contractors can also benefit from dedicated services such as EnviroMix Impact, which affords the environmental impact calculation of a concrete mix design plus a formulation strategy adapted to carbon reduction targets. Chryso also offers a digital solution for real-time monitoring of its Maturix concretes, which are designed for high early compressive strength in precast or cast-in-place conditions. 

“With this comprehensive EnviroMix product range, Chryso is creating new development levers for the construction industry by delivering solutions to produce the cements of tomorrow,” says Concrete Business Unit Director Frédéric Guimbal. “EnviroMix also offers the control of concrete admixtures using new binders, the formulation and real-time monitoring of low-carbon concretes on building sites while providing an accurate measurement of their CO2 impact.

“The construction industry is accelerating its transformation to manage and reduce environmental impact. Carbon dioxide footprint is a major challenge in the development of concrete formulations, coupled with the traditional properties of this material, and at the heart of our construction techniques (classes of strength and durability, workability, setting time).”

Over the past 15 years, he adds, Chryso has bolstered its expertise in the field of low carbon impact concrete admixtures. Backed by an innovative technological portfolio, the company also benefits from specific know-how adapted to the chemistry of new low-carbon cements via its cement additives offerings. Chryso solutions dedicated to a low carbon transformation are based on multiple scientific collaborations and industrial partnerships that reinforce the knowledge of geopolymers, calcined clay cements and other new binders.
