Construction materials

The Dequest range includes phosphonates, polymers and inulin derivatives, the latter being designed for an improved environmental and toxicological profile. Dequest phosphonates are extremely effective in retarding the hardening of cement while Dequest inulin derivatives are excellent plasticizers for cement at ambient temperatures.

The Dequest phosphonates extend the cement setting time to allow for:

1. Placing cement in very hot environments such as oil wells and geothermal wells

2. Reclaiming unused cement from construction sites at the end of the day (setting is delayed overnight by the addition of Dequest phosphonates)

3. Premixing of large amounts of cement for construction in hot and dry climatic conditions, and

4. Pumping cement over long distances
