DARACEM® ME1 is a melamine formaldehyde resin which when introduced into concrete will produce high workability concrete which is virtually self-levelling and requires little or no vibration during handling and placing. In addition, it can be used to effect large water reductions in concrete of normal workability to achieve higher early and subsequent strengths.

DARACEM ME1 Powder is a white crystalline material which must be dissolved in fresh potable water to make up a 20% solution (1 part DARACEM ME1:4 parts water) before use.
DARACEM ME1 can be used with all types of Portland, Pozzolanic and Blast Furnace cements. It can also be used with fly ash and silica fume.
DARACEM ME1 should not be premixed under any circumstances with other admixtures. While some admixtures can be usefully combined within the same mix the performance of this product may well be affected by the presence of other chemicals and we recommend that GCP Applied Technologies be contacted for advice in all such circumstances.
The performance of DARACEM ME1 is best assessed after preliminary trials on site using the actual mix constituents under consideration to determine the optimum dosage and effect on concrete properties, such as early age and ultimate compressive strengths, workability retention, set retardation and shrinkage, when these are of consequence
As a guide to these trials, when used in liquid form, an addition rate of 1000 ml–2000 ml DARACEM ME1 per 100 kg cement is recommended. For advice and assistance with our trials we would recommend that you consult our Technical Department.
An overdose of the recommended amount of DARACEM ME1 can result in slight set retardation. The ultimate strength and properties of the concrete however will not be impaired, providing the concrete is cured properly
It is preferable that liquid admixtures for concrete should be introduced into a mixer by means of automatic dispensing equipment, details of which are available upon request.
For further information see the DARACEM® ME1 SDS (Safety Data Sheet) or consult GCP.
DARACEM ME1 powder is supplied in polythene-lined paper sacks. Net weight 30 kg. Other packaging by special agreement.
DARACEM ME1 Liquid is supplied in 210 litre free, nonreturnable drums.
Alternatively, 1000 litre IBCs or bulk deliveries can be arranged.
DARACEM ME1 Powder is hygroscopic and an unopened bag can be stored several years under dry conditions. A partly used bag should be tightly closed and used within a short period of time.
DARACEM ME1 should be stored in original containers or suitable closed tanks, preferably out of direct sunlight and protected from extremes of temperature, where its storage life is at least one year.
If the product does become frozen it should be carefully mixed after thawing out to restore it to its normal state.
