Description. Diethanol-isopropanolamine (DEIPA) is an alkanol amine used in the formulation of cement additives and concrete admixtures. Besides being a good grinding aid in the cement mill, DEIPA increases the strength of cements at all hydration ages, and cements blended with fly ash and slag tend to show a greater response to the …

The dosage rate of MTDA® will depend on the fineness and the re-agglomeration characteristics of each cement. Typical dosage rates will vary from 0.01% - 0.05% by weight of cement for Types I & II cements and from 0.04% - 0.08% by weight of cement for Type III cements. The optimum dosage rate must be determined during full …

Triethanolamine is considered a popular grinding aid. Its effects on cement characteristics depend on the type of cement and dosage. An addition of 0.025% of Triethanolamine to Portland cement, acts as a set accelerator, at 0.25% as a mild set retarder, at 0.5% as a severe retarder and at 1% as a strong accelerator.

Section snippets Experimental. Six samples of commercial grinding aids were supplied from Heracles General Cement Company of Greece. They were first characterized by a Nicolet 560 IR Magna Fourier transform spectrophotometer, in the range of 4000–400 cm −1 with 200 successive scans. The spectrometer was equipped with a …

the industrial grinding of cement, even without the use of grinding aids Therefore it can be assumed that the surfaces of the majority of commercial clinkers are predominantly or even completely hy droxylated This is also important because it assists the grinding, in other words water is a weak grinding aid The chemical reaction of oxide ions ...

Compressive Strength • TIPA increase 7 days and 28 days compressive strength of cement. • Optimum dosage is 0.01-0.02% for the enhancement of strength by TIPA. • If dosage>optimum dosage it can increase the strength further very little but it is not economical. • Higher dosage of TIPA can cause air entrainment in cement.

Clearly, such effects must be considered when designing grinding aid formulations [2-4]. This paper investigates the effect of various polyols, used as grinding additives, on selected properties of cement. The polyols investigated include ethylene glycol, propylene glycol and several derivatives or analogues of these glycols [1]. 2.

CHRYSO ® Reductis 50 reduces significantly the Hexavalent Chromium content in cement even at low dosages. It allows to maintain durably the Chromium VI content below 2 ppm to be in line with the 2003/53/CE European standards. Limited installation and maintenace costs. CHRYSO ® Reductis 50 is a liquid solution easy to introduce through a ...
