Hexavalent Chromium in Portland Cement - ASTM International

Hexavalent chromium has been classified as a carcinogen, and its release into the air or groundwater is regulated and controlled under many Federal and State regulations. In addition to carcinogenic risks, soluble chromium has long been linked to chromate-sensitive contact dermatitis of workers exposed to wet cement or concrete.

CHROMIUM ** Chromium deficiency is a major factor in the development of heart disease (heart attacks, hardening of the arteries). Chromium is stored principally in the kidneys, spleen and testes, with trace amounts found in the heart, lungs, pancreas and brain. The body cannot easily absorb chromium if other minerals are out of balance as well.

Solids and Metals - Specific Gravities - Engineering ToolBox

The Specific Gravity - SG - is a dimensionless unit defined as the ratio of density of the material to the density of water at a specified temperature. It is common to use the density of water at 4 o C (39 o F) as reference - at this point the density of water is at the highest.. Specific gravities - SG - for common solids and metals can be found in the table below:

Hexavalent Chromium in Cement Manufacturing - Uniwin Chemical

INTRODUCTION. The purpose of this review is to summarize information related to hexavalent chromium, Cr (VI), in the portland cement industry. The catalyst for initiating this project was the content restrictions and labeling/marketing of cements based on the level of Cr (VI) in cement in Europe, and the potential for a similar situation in North America in the near future.
