Alpha Portland Cement Company Blueprints and Concrete Plans
These came in a folder that I found in an old box of maps and blueprints from an architect’s estate. Although not a book, they are in the public domain and interesting so I thought I would post some crude copies. I have not edited them or cleaned them up, and there is some loss to the margins on most of them because they were a bit too large for a scanner. The actual plans are almost all there, though. I figure anyone who is interested can clean them up after download if need be (although they are perfectly usable as they are now). I have posted them at very high resolution (about 6500 by 4500 pixels) to preserve details and lettering.
I gather this series, all from 1920-1920, was an effort by the Alpha Portland Cement Company to promote the use of concrete and cement in building. I think I have almost a complete set here, but I have no definitive reference as to what plans were included.
As always, these high resolution JPEG images are all free of charge and ready to be downloaded one at a time or in bulk via a ZIP file. Donations to support this site and project are always welcome, but by no means required.
Many of the originals I sold on eBay for $10 to $30 each. There is a small market for these as collectibles. I am happy to sell any originals I still have for $10 each. Here are the titles of those still available:
Here, in no particular order, are many sample images. All 38 or so images may be browsed and viewed in their full resolution in the GALLERY.

I am looking for plans to build a spring house. If you have any plans available that I could use, please let me know. Thank you

Hi Bernard,
The spring house plan here is the only one I have.

Hi,
I was wondering if these blueprints are in the public domain now, since they’re so old? I’m doing a little research into how exactly public domain works, but if you have a quick answer, I’d truly appreciate it!
Wonderful project you have here!

Hi Justin,
Yes, I will not knowingly post anything here that is not public domain. Generally, anything published in the US during or before the year 1922 has now passed into the public domain. It is a bit more complicated than that, especially for later years, but that is a rough first guide. These blueprints were all published before 1920 so are fairly certain to be out fo copyright.
For later works, or many works form other countries, there are longer periods of protection.
Thanks for the comment.
