Glenium ACE 499 

An essential component of our ZERO ENERGY SYSTEM, is based on newly developed polycarboxylate ether polymers. The particular molecular configuration of GLENIUM^® ACE 499 products accelerates the cement hydration by exposing increased surface of the cement grains to react with water. As a result, it is possible to obtain earlier development of the heat of hydration, rapid development of the hydration products and, as a consequence, higher strengths at very early age. The polymer structure of GLENIUM^® ACE 499 products is specially designed to improve the rheology of precast concrete, making it very flowable and low viscous even at very low water/cement ratios, without increasing stickiness. Robustness is a distinctive feature of the precast concrete produced with GLENIUM^® ACE 499 products.

Features and Benefits

GLENIUM^® ACE 499 offers the following benefits for the precast concrete industry:

• Capability of delivering high quality concrete at any time to the job site in place.
• Production of highly flowable, robust selfcompacting concrete having a low water cement ratio along with an optimal rheology.
• Enhanced robustness and consistency in concrete quality with low stickiness.
• Environmentally friendly, CO² reduced mixdesign optimization.
• Potential elimination or reduction of heat curing.
• Improved surface appearance.
• Durable precast concrete elements as per EN 206-1.
• Elimination of the energy required for placing, compaction and curing (ZERO ENERGY).
• Optimization of the curing cycles by reducing curing time or curing temperature. Increased productivity, particularly in combination with XSeed^® 100 Crystal Speed Hardening.
