Optimisation of plasticizers for gypsum applications - ZKG
Following their adoption in cementitious systems, superplasticizers based on polycarboxylate ethers are now increasingly being selected for gypsum applications. Binder-specific additive optimisation produces plasticizers with an enhanced water-reduction capability and simultaneously reduced setting times. In recent years, PCE-based plasticizers

Plasticizers: Types, Uses, Classification, Selection & Regulation
Due to its low cost and generally good performance, DEHP is widely employed as a plasticizer in manufacturing articles made of PVC. Melting point: 50°C Boiling point: 250 - 257°C at 0.5 kPa Structure of DEHP DEHP offers good gelling, satisfactory electrical properties and helps to produce highly elastic compounds with reasonable cold strength.
Plasticizer
Sebacate - based plasticizers provide excellent compatibility with a range of plastic materials and synthetic rubbers (specifically nitrile rubber and neoprene), superior properties at low temperatures, and good oil resistivity. Some examples are: Dibutyl sebacate (DBS) Di- (2-ethylhexyl)sebacate, Di-octyl Sebacate [15] (or DOS plasticizer)

- How to mix gypsum & plasticizer?
- We recommend to start with 2% by cement weight, then lower the dosage as needed. How to mix with Gypsum: Add Super plasticizer to the water 10-15 minutes prior mixing until plasticizer dissolves in water, then add gypsum to pre-measured water and mix with mechanical drill. Plasticizer dosage rate - 0.25% by Gypsum weight.
- What is the cost of gypsum?
- The cost of gypsum varies with its moisture content. Wallboard manufacturers incur a cost of about $1 per ton per 5 percent reduction in moisture content, so very dry gypsum is required for wallboard production.
- How do I mix super plasticizer?
- You can also add Super plasticizer to the water 10-15 minutes prior to casting (until plasticizer dissolves in water), then mix with dry ingredients. Please note: Concrete minimum mixing time is 3 minutes with mechanical drill or 5 minutes with mortar mixer (it takes a few minutes until Super Plasticizer absorbs into the cement and start reaction).
- How much superplasticizer do I Need?
- Superplasticizer dosage is 0.2- 2 % by weight of binder. For 100 lbs (45.3 kg) (bag of cement) you'll need approximately 2 lb ( 0.907 kg) of GlobMarbe superplasticizer. How to mix with Cementitious Material: Mix pre-mixed concrete or cement with plasticizer for a few minutes, then add water (mix at least 3-5 minutes).
- What is melment F 10 gypsum?
- Water-55% by Gypsum weight. Melment® F 10 is a free-flowing, spray dried powder of a sulphonated polycondensation product based on melamine. Superplasticizer is especially optimized for plastification and water reduction of cement and calcium sulphate based materials. Superplasticizer provides an excellent development of early strength.
- How much superplasticizer do you need for cement & calcium sulphate based materials?
- High-performance superplasticizer for cement and calcium sulphate based materials Superplasticizer dosage is 0.2- 2 % by weight of binder. For 100 lbs (45.3 kg) (bag of cement) you'll need approximately 2 lb ( 0.907 kg) of GlobMarbe superplasticizer.
