Apr 10, 2009#0183;#32;When ethylene glycol (EG) is solidified with cement, the EG appears to occupy at least 3 different kinds of sites, characterized by differing extractability. Gross alterations of the morphology of the cement matrix do not become apparent until rather large amounts of EG (EG/cement = by weight) have been added to the hydrating cement mixture.
A grinding aid composition for cement clinker grinding comprising an alkanolamine compound that is a primary alkanolamine compound a secondary alkanolamine compound or a mixture thereof and a grinding aid composition of claim 1 wherein the primary alkanolamine compound comprises one c 2c 8 hydroxyalkyl group.
26/3/2017#0183;#32;Below chemical regent are normally used as cement grinding aid: three isopropanolamine, ethylene glycol, triethanolamine, sorbitol, diethylene glycol, glycerin, etc. Because of the bad adaptability, stability and imperfect function, singlecomponent cement grinding aid is difficult to meet the requirements of grinding aid; Also the macromolecular synthetic grinding agent technology is still

Effects of Adding Boron Compounds to Glycol Based Grinding
A grinding aid composition suitable for grinding clinker into hydraulic cement powder, an improved grinding process and an improved cement product are disclosed. The grinding aid composition is composed of a mixture of at least one alkylene ether glycol and particulate carbon.
24/1/2019#0183;#32;be considered as the most popular grinding aid in cement industry. However its action on cement pastes is very complex and depending Triethanol amine and ethylene glycol are used as grinding aids for Ordinary Portland Cement (OPC). Standard water of consistency, Blaine area, initial and final setting times and compressive strength are tested for OPC. The phase composition and
10/4/2009#0183;#32;The effects of ethylene glycol on the setting reactions of hydrating Portland cement and on the eventual structure of the hydrated cement paste have been studied by a combination of techniques including solvent extractions with solvents of varying polarities, scanning electron microscopy, and Xray powder diffraction. When ethylene glycol (EG) is solidified with cement, the EG appears to
In the study the performance which previously achieved with glycolbased grinding aid as 9% increase in production was easily achieved as 16% production increase with the glycolbased grinding aid formulated with PCE [15] . PCE reacted like low molecular weight compounds in cement grinding and subsequent hydration reactions. Duanle and others investigated the effects of organic compounds

What is claimed: 1. A grinding aid composition for cement clinker grinding comprising a mixture of at least one alkylene glycol represented by the formula: HO(AO) n H wherein A represents a C 2C 3 alkylene and n is an integer from 1 to 5 and particulate carbon in a weight ratio of alkylene glycol to carbon of 1: to 1:. 2.
The results showed that use of grinding aid improved the grinding performance of the mill as finer size distribution than that of no grinding aid was obtained at the same milling condition. The
Jan 24, 2019#0183;#32;Triethanol amine and ethylene glycol are used as grinding aids for Ordinary Portland Cement (OPC). Standard water of consistency, Blaine area, initial and final setting times and compressive strength are tested for OPC. The phase composition and microstructure of the formed hydrates are tested using DTA/TG and SEM techniques.
The invention relates to a preparation method of a cement grinding aid, and the preparation method comprises the following steps: mixing triisopropanolamine with water in the mass ratio of 1:3 to 1:5, heating to 40 to 50 DEG C, until the triisopropanolamine is completely dissolved, to obtain an A solution; adding silica fume to dodecylbenzene, stirring to fully dissolve to obtain a B
