Plasticizer
In normal plasticisers, the active substances are adsorbed on to the gypsum particles, giving them a negative charge, which leads to repulsion between particles. Lignin and naphthalene sulfonate plasticizers are organic polymers.
BASF - Interior Construction Solutions
Comprehensive range of foaming agents for producing different pore size lightweight gypsum wallboard; A wide range of superplasticizers for high water reduction, production energy saving, and productivity improvement; Advanced lab competency to reduce your testing time and effort, and material cost as well
POWDER FORM The multifunctional additive for higher quality
Plasticizers Retarders All the above additives are compatible with PLAST RETARD PE. PLAST RETARD PE can be used advantageously in neutral gypsum formulations avoiding the traditional use of lime. Lime is well known for modifying gypsum setting properties. Adding PLAST RETARD PE, on the other hand, does not modify the adherence power of
Optimisation of plasticizers for gypsum applications
Currently, solutions of polycarboxylate esters are widely used to improve the technological properties of concrete, mixes, and gypsum products (Hampel et al., 2013), as well as ceramics: cement
Impact of Plasticizers on Technological Properties of Gypsum
The results indicate that plasticizers in PG based gypsum binder could reduce W/B ratio from 1.15 down to 0.4. ... impacting not only on quality and accuracy of the final product, but also on his
- Who makes gypsum?
- Founded in 1901, USG is still the largest manufacturer of gypsum products in North... Slated to become the tallest mass timber project in the country, Framework was a... The British designer will display seven new products at the Salone del Mobile.
- Are Polycarboxylate ethers suitable for gypsum?
- 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.
- Do PCE based plasticizers reduce water-reduction efficiency in pure gypsum?
- The structure of PCE-based plasticizers was therefore modified in order that these products would exhibit their greatest water-reduction efficiency in pure gypsum phases, such as alpha- and beta-hemihydrate or anhydrite. Heterogeneous...
