Development history and evolution of cement

2018-11-23  Development history and evolution of cement grinding aids Since the 1930s, cement grinding aids have been used in the cement industry. The earliest patents of the 1930s tested and used powdered mixtures of mineral oil, animal oil and petroleum cracking residues to improve the water resistance of cement products and improve the high early strength and processability of cement.

Grinding aids for high performance cements

2018-3-29  Grinding aids are organic compounds that are added to the mill during cement grinding. Their main purpose is to reduce the energy required to grind the clinker into a given fineness. In addition, some products (usually referred to as performance enhancers) provide positive effect on cement hydration improving strength development. In this paper we present a typical example of full investigation about the possibility of producing high early strength type I cement, using an appropriate cement

Comprehensive understanding of grinding aids

2016-10-2  Grinding aids have been used successfully for dec ades in cement production and many other areas, such as ceramics, pigments etc. The main effect is to reduce energy consumption and increase the grinding efficiency. Additional features can be improved e.g. powder flowability and strength development of binders. There is surprisingly lit-

But some cement manufacturers refuse to use grinding aids for economic reason. Locher and von Seebach [5] investigated the use of organics in cement dry grinding and found that the use of chemical additives does not affect the breakage of coarse material and become a factor when fine material builds up in the mill. This conclusion was in parallel to literature [4]. In their work found that grinding aids
