Product description
High-Performance Admixture based on CHRYSO® EnviroMix® technology, specially designed for high SCM concrete mix designs. CHRYSO offers a complete range of innovative solutions for ready-mixed concrete, in plant or on site – aiming to improve the performance, production, workability, aesthetics and durability of concrete.
CHRYSO® EnviroMix® 728 provides high early strengths to increase SCM content in concrete and achieve substantial savings. It provides optimized workability and placeability to achieve targeted concrete quality and performance on-site while reducing jobsite time and costs.
Interpretation
Based on the results from the life cycle assessment model, the life cycle impacts are strongly driven by the raw materials. The impacts of the raw materials are primarily attributed to the polycarboxylate in the product recipe. The manufacturing of EnviroMix also drives the Global Warming Potential. The electricity consumption is a significant contributor to the manufacturing impacts.
LCIA results are relative expressions and do not predict impacts on category endpoints, the exceeding of thresholds, safety margins or risks. EPDs are comparable only when they follow the same PCR, functional unit and system boundary. The full EPD (PDF) contains the methodology, scenario assumptions and verification statement.
