Information on Cement Industries

Hi Sherif Allam,

Can you provide a little more information for us? What do you already know? What have you researched? What do you plan to do with this inofrmation? Start a business? etc.

The more you let us know about your overall needs and your level of experience with the subject matter, the easier it will be for someone on this site to point you in the right direction. The question that you've asked is so wide open that I wouldn't even know where to start, other than to point you to a wikipedia entry on cement - but that may be too basic for you. I don't know.

Cement industry in South Africa

The editors advise is correct-we do not know all about cement to this day even though it has been in use for centuries. Consider that the soil used varies along with the proportions of the mix itself -hit the internet and learn for yourself all you can .

Perhaps my question (and the eventual answers it may receive) will help the initial inquirer.

I am interested in locating specific information on the use of industrial smelter slag or "scoria". Is there a member who has experience of the use of slag being produced from electrical smelter ovens that are used to produce : nickel matte ? Thank you for your help.

The use of scoria is well known in the cement industry.If the scoria price is less than the clinker cost you can replace up to a maximun of 50 % in order to reduce the final cost of cement. The % you can add depends on the clinker and scoria quality.If you have more specific question you can contact me at :barciona@yahoo.com

Unless the concerned scoria has cementitious properties,it generally can only be used as filler. Thus the percentage of filler may be low.

It follows that uses of : filler , needs : cheap price and low transport cost unless used at the point of :smelting.

This discussion may have a greater economic interest if the use of scoria does in any way possible bring benefit to a reduction of carbon in the portland or new type of cement . This implies that it may achieve nett C02 reduction whilst maintaining the same or better characteristics as: normal or standard portland Cement.

Whether or not the effect of carbon credits become prevalent remains to be seen. I will closely watch the outcome of this discussion.
