Cement Additives & Services for Producers. ... More than 80 years ago, we pioneered the development of chemical additives to make grinding cement more efficient. Since then, we have led the industry in making new compounds to improve cement grindability and performance.
Whatever is the additive used (pure grinding aids, specifically designed to increase production and fineness, or performance enhancers with effect on cement hydration), the choice of the most appropriate relies on a detailed investigation that should consider all the characteristics of the cement. Grinding aids for high performance cements
Alibaba.com offers 522 grinding additive products. About 10% of these are textile auxiliary agents, 10% are surfactants, and 8% are coating auxiliary agents. A wide variety of grinding additive options are available to you, such as coating auxiliary agents, petroleum additives, and plastic auxiliary agents.
shown that the usual grinding aids and also con-crete additives are well able to withstand normal grinding conditions. Appreciable decomposition is, however, possible if the cement is stored for weeks at above 50 °C temperature. This can occur if silos are filled with hot cement. Mostly adsorption of grinding aids is revers-ible.
Dr. K. Senthilkumar et al /Int.J. ChemTech Res.2014,6(9),pp 4428-4433. 4429 effect and consequently provides more efficient grinding13.As it is known, grinding is a complex process, a single mechanism cannot be expected to be responsible for explaing the influence of different types of grinding
Chemplex ® additives are formulated with the proper balance of abrasive and lubricious constituents that promote the grinding and pelletizing processes. The resulting sample pellets when the Chemplex ® additives are used are characterized with unblemished smooth surface appearing “plasticized”. The Chemplex ® additives are available in a variety of formats that make them very simple to ...
