EUNICEM P7 is a high performance, liquid concrete plasticizer or water reducing agent used to improve workability of concrete mixes or to permit eective reductions in the free water content. It is extremely versatile in application and is eective over a wide range of mix designs from low through to high cement contents. A special feature of this product compared to conventional plasticizers such as those based on lignosulphonic acid derivatives, is its ability to increase ultimate compressive strengths, even at constant water: cement ratio. When used as a water reducing agent, both early and ultimate strength development, is markedly improved. EUNICEM P7 can be used to reduce permeability of concrete. EUNICEM P7 functions by adsorbing onto the surface of the cement particles in a concrete mix, resulting in a powerful deflocculating action and hence a more uniform dispersion of cement grains throughout the mix. This in turn leads to a higher degree of lubricity and a consequential increase in workability. EUNICEM P7 is formulated from a carefully selected blend of both synthetic and naturally derived raw materials and is manufactured under controlled conditions to give a consistent product which depending on addition rate conforms to Type A and D materials of ASTM designation C494, and complies with BS 5075, Part 1.
EUNICEM P7 is supplied ready for use. It should be added to concrete mixes during the mixing process, at the same time as the water. It should not be added directly to the mix. No extension of normal mixing time is necessary.
• Superior to conventional lignosulphonic acid derivatives, particularly in relation to water reduction and compressive strength development.
• Can be used to improve workability and simultaneously increase compressive strength.
• Can be used to extend workability and thus the period of time within which the concrete can be placed and compacted.
• Will increase workability of most types of concrete mix. Harsh mixes, such as those containing crushed rock aggregates, are considerably improved in the plastic and hardened states.
• Permits water reductions in the region of 10%-15% with a corresponding increase in strength, impermeability and durability.
• Can be employed to modify mix designs in order to achieve cement economies.
• Is effective over a wide range of cement contents. Maintains effectiveness even at very low cement contents.
