Lomar®-D-Powder-Admix is a high-range water-reducing concrete admix that is far more powerful than ordinary reducing aids. This superplasticizer greatly reduces the amount of water normally required to impart workability to a concrete mix.

This dispersing agent promotes the separation or deflocculation of the cement particles by overcoming the cohesive forces that attract them. This effect is evident on other types of pozzolanic material such as fly ash, or blast furnace slag.

The strong dispersing action of this product causes the concrete to flow much easier than a conventional mix. This effect is called plasticizing.

As a superplasticizer, it gives concrete mix optimum plasticity and allows it to be placed better at the working site. In addition, its use allows a lowering of the water-cement ratio without loss of slump. This results directly in an increase in early and ultimate compressive strength of the concrete.

Lomar D is non-foaming and non-toxic. Because it is synthetic, it always exhibits uniform properties. It is temperature stability is over 150°C (300°F). When used at normal suitable dosage levels, it will not significantly affect the concrete’s heat of hydration. Nor does it contribute to reinforcement corrosion or mold growth.

Features & Benefits

• Permits lowering of water-cement ratio while maintaining strength
• Quicker and easier mix placement
• Increased early and ultimate compressive strength from water reduction
• Allows quicker mold turnover time for pre-casters
• Minimizes energy required for curing
• Improve finish of cast concrete by minimizing honeycombed surface
