Concrete Mixes - good reference?

Concrete Mixes - good reference?

Concrete Mixes - good reference?

(OP)
Hey - I am in need of a good book on concrete mixes.  Specifically, I need information on admixtures and recommendations of such for different applications.  I have a large environmental structure and need options to consider for reducing heat of hydration and avoiding the side effects of water reducers and other possible admixtures.  
Thanks  

RE: Concrete Mixes - good reference?

Call an admixture company and ask for their rep to pay you a visit to discuss.

RE: Concrete Mixes - good reference?

Try PCA for "Design and Control of Concrete Mixtures". Very basic & good book. Also try PCA or ACI for consideration on Mass/Environmental Concrete, or jut get the references from the book mentioned above.  

RE: Concrete Mixes - good reference?

Agree with kslee1000...Design and Control of Concrete Mixtures is the de facto "Bible" of this subject. You might also consult ACI 304 "Guide for Measuring, Mixing, Transporting and Placing Concrete"  

RE: Concrete Mixes - good reference?

Glad to have a straight shot here, and been backuped by Ron.

 

RE: Concrete Mixes - good reference?

Most books may not have the current information that has been developed since the increased emphasis on different admixtures, raw materials and research.

The is all driven by the cement companies and admixture companies jointly and not like it was a few years ago before the international control of the admixture and cement promotion. - No more "Ma and Pa" verses the world mentality.

PCA is a trade advocacy/promoting/research group, if they are not leading, won't fall behind too far, especially on special/practical practices and considerations. At this moment, I don't have the firsthand knowledge on their's standing industry-wide. but I always have very deep respect for them, at least as a first stop for general knowledges.

RE: Concrete Mixes - good reference?

Ideas for reducing heat of hydration:

1) Use ice for some of the water in the mix design.
2) Reduce the cement content by as much as possible.
3) Cool the coarse aggregate prior to mixing.

The first two are cheapest and easiest to do.

RE: Concrete Mixes - good reference?

For lower heat of hydration, in addition to peinapod's good advice is to use Type IV portland cement (might be a bit hard to find, but is formulated for lower heat of hydration).  Type II cement reduces the heat of hydration more than Type I, but not as much as Type IV.

add flyash
pour concrete at night and during cooler months
make sure your bulk cement is cool
