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:
- Placing cement in very hot environments such as oil wells and geothermal wells
- Reclaiming unused cement from construction sites at the end of the day (setting is delayed overnight by the addition of Dequest® phosphonates)
- Premixing of large amounts of cement for construction in hot and dry climatic conditions, and
- Pumping cement over long distances
