Triisopropanolamine is one of cement grinding aid raw material,it can improve the compressive strength obviously.

When we prepare a concrete for a project, usually the concrete admixtures will be used to get better performance concrete for construction standard.First, we use concrete water reducer to get a good cement/water ratio that concrete can be unload easily at construction site.

Cement grinding aid is a kind of chemical additive to improve the grinding effect and performance of cement, which can significantly increase the yield of cement, the strength of cement at all ages and improve its fluidity. Cement grinding aid can greatly reduce the phenomenon of electrostatic adsorption and ball encapsulation in the process of grinding, and can reduce the tendency of superfine particles agglomeration again in the process of grinding.

People use concrete water reducer from long time ago, has developed the first generation of ordinary water-reducing agent represented by calcium lingnosulfonate and take the naphthalene formaldehyde water reducer as second generation high performance superplasticizer stage. From early 1980s, polycarboxylic acid superplasticizer was adopted more and more and has a sustaninable development.

AEO is one of fatty alcohol polyoxyethylene ether (RO(CH2CH2O)nH),what determines its chemistry is carbon chain(C:12),it made of natural fatty alcohol and ethylene oxide,suitable low temperature washing at civil & industial detergent.

Latest news on ethylene oxide,adjust price upward RMB700/MT at North china area,follow the price raise of peregal raw material ,the export price raise too,it bring huge pressure to export trader company,but no pressure and no motivation,just like a proverb "Blessing in disguise",it mean that not sure it is a bad thing for us,maybe will bring good news.

Along with the development of science and technical,the development of polycarboxylate superplasticizer have rapid growth recent years,it have widly use in concrete construction.Althought it have good waer reducing effect and use convenience ,But in practical application , have some special problem itself.

Recently, Dow Chemical Europe Limited announced force majeure, with immediate effect. It is suitable for all polyether polyols containing ethylene oxide (EO). The influence devices are temeuzen in the Netherlands and Tertre in Belgium.EO production has been interrupted due to accidents and unforesee
