Concrete Admixtures

Concrete Admixtures

Concrete Admixtures

(OP)
I m looking for an online resource that will start me off on a guideline i am starting to make. I want to find out the typical base chemicals that are used in both concrete plasticisers and retarders (my expectation being that a retarder for example could be based on 2 or 3 different chenicals). Once i have this as a starting point i will consider any advantages (perhaps cost) or disadvantages (perhaps causing "stinkiness" of the mix). I will check also for any reported compatibility issues. Any body got suggestions where to find any information?

RE: Concrete Admixtures

Most of that information is proprietary and you won't get much of that. General information can be obtained from the American Concrete Institute and the Portland Cement Association.

You can try getting the Material Safety Data Sheet for each admixture. Sometimes that goes a little beyond the proprietary information.

RE: Concrete Admixtures

Zambo,

If you're looking for the types of compounds in general I would highly suggest purchasing "Design and Control of Concrete Mixtures" 15 or 16 Ed. The older additions can be found online as PDFs if you don't want to pony up for the hard copy.

If you're looking for something specific, like the chemicals in Sika HRWR then as the poster above said, it's usually proprietary information and not available.

RE: Concrete Admixtures

As Ron noted, check the MSDS sheets.

RE: Concrete Admixtures

Type this search string into Google and you will find numerous online resources from both professional associations & manufacturers.
