No mistake Mark, just exchanging information !
It is a regional thing, that's for sure. And the time period also makes a difference, as to methods and technoligy.
I worked the the Tampa, FL area for a short time, (1978) in the trades, concrete, and the first time I discovered that the major portion of the aggregate in the mix was shells!. Yea, you dig a pit in that part of FL. you get sand and shells.
But I digress, back to the topic of moving all this by rail.

mbinsewi softail86mark Cinder blocks are called that because the aggregate used is a lightweight expanded shale which was "cooked" to expand it. Hence, cinders. It has nothing to do with coal. My family was in the business of making them since WWII. Thank you! Although what your family makes with the shale process, is more commonly called "light weight" block" in these parts. No granulated coal or volcanic cinder involved. It's easy to tell when you demolish a building buildt with "cinder blocks", as the are very porous, and dark in color. Because of the materials used, they were also "light weight", compared to todays CMU's. I have to stick with my original post, in that the period before, and during the depression, around the industrialized area of SE. WI. and Northern IL., including the Chicago area, some amount of coal clinker was used in making "cinder blocks" I've never made'em, but I sure have laid my share. Mike.

My mistake. Not having done it myself in literally 45 years, I must admit I've let my knowledge lapse a little. Plus, I'm in California and don't know all the construction and manufacturing processes of the other states in other times.
Thanks for the lesson, Mike...

Agreed, fly ash is still used, especially in "designed" concrete mixes, replacing up to 15% of the cement used.
It's fine for walls and footings, but it's difficult, to say the least, to get a good finish for floors. You want to limit it's use in floors to about 10%, which most redi-mix plants don't. You have to ask for it when you order, or make sure it's in your specs. when getting bids on concrete for big jobs.
You also have to ask for a concrete mix without fly ash, if that's what you want, or you'll get the fly ash mix anyway.
It was once a boon to the redi-mix cement companies, the power companies gave it way for little or nothing, you had to pay for the trucking, and the facilities need at your redi-mix plant to store it.
Not sure how it all works today.
It's use in CMU's, the finished product is called "light weight" block. Light weight block is not what was once considered cinder block, although it may have been one of the ingredients.
Light weights are still used.
Plenty of makers did use fly ash as the aggregate, though.

mbinsewi Cinder blocks were made from cinders, because back then, just about evey industry used coal, along with homes. Today they are made of concrete, cement and aggregate, and are called CMU's, concrete masonry units. Mike.

Kaiser had a plant at Sunnyside in Niles Canyon where it was produced. Any of you Bay Area railfans going to the railroad up there knows where it is.
We use concrete bricks for commercial concrete work, to support reinforcing steel (rebar) in footing, pads and concrete grade beams. We refer to them as do you brick, and they are just gray nominal 2”x4”x8” pieces that come on pallets. I can totally see these shipping by rail, either boxcar or flat. Also, the shortline I am going to be modeling, our local Northern Lines Railway out of St Cloud, Minnesota, services Borgert Concrete Products in nearby St Joseph. They make concrete block, culverts and pavers, and ship some of this outbound by rail: gondola, flat/bulkhead flat, boxcar. There is also a specialty concrete manufacturing plant in Elk River that is right by the BNSF tracks which, if not now, at least recently, would ship by rail. They make bridge beams, concrete duct bank units, jellyfish tanks, etc, which can be shipped by rail. Their yard is full of all kinds of unusual and large concrete specialty items.
PED My late 70's layout has a concrete plant. Inbound products include rock, sand, cement and fly ash. I would like to add an outbound product. The plant makes concrete blocks, bricks and other finished concrete products. Would those products be shipped by rail in late 70's? Flatcar? Boxcar?

If you want to make interesting open loads you could make prestressed cast concrete products at your plant. There is a plant near here that makes those products and it used to be rail served. These days the product leaves the plant on trucks, sometimes they are huge oversized loads like bridge beams.

Sorry to jump late. Great discussion about cement since this is something I also plan to replicate. Here's a similar post on such a topic on the hobbyist webpage:

Concrete rail ties, first used in 1896. Not made just any old place.

Lone Wolf and Santa Fe Concrete bricks are actually called cinder blocks. They are very common in construction because they are hollow and are reinforced with rebar and cement. They are usually shipped by trucks but they might be inside of boxcars. Anyway large concrete sewer pipe and concrete railroad ties are the most common concrete items that are shipped by rail.

Wrong. Concrete bricks are called bricks. They ere the same shape as a clay brick and often a bit larger and more porouis. I have purchased them, used them and seen them in building construction. Often used for a solid wall when the wall will get a stuco finish.

7j43k Bricks are different than blocks. Bricks are made from clay and they are "cooked" in kilns. Blocks (concrete) are cast from, yes, concrete. The process does not involve heating the concrete. So a concrete plant wouldn't make bricks. Because making bricks is more complex than making blocks, it is more expensive to build the plant. So they will be farther apart. Which can explain why bricks are more likely to be shipped by rail than concrete blocks. Also, as noted by a poster above, there are all kinds of bricks. And someone might just HAVE to have bricks from a long way away. Concrete blocks ain't that special. Ed

Ed,I thought that too every just about every time we set that boxcar of concrete blocks off at Maysville.
After the sales of tobacco at the Maysville tobacco warehouses we would pick up several boxcar loads of dried tobacco.

My local Lowes and Home Depot both sell concrete bricks in various colors. Used for landscaping and patios. Also sell concrete paving stones and stepping stones in various shapes.

I did not know that. I've never seen them used, but here in California, masonry construction is not terribly popular.
Concrete pipe, like for sewers, could be shipped by rail. Usually on bulkhead flats. Models of such are available via the standard websites.

Just another thought. There are transload areas for building products. Products get shipped by rail to these sites, where trucks then come and pick up the assigned load for various customers in the surrounding area. It works well when no one customer is large enough to get products by rail, sort of a team track area specifically designated for building materials.
One of these transload areas could be a destination for your brick/block plant.
Thanks all. All I needed was a "plausable" outbound load. The plant I have in mind makes a variety of concrete products...not just blocks and bricks. I think I will ship in boxcars rather than open flats so I don't need to display the actual products.
7j43k don't ship by rail,

When I worked on the Chessie(C&O) we would setout a boxcar of concrete blocks on the Maysville(Ky) House track once a month--yes that was what the team track was called because it was located on the former freight house track..
The problem with a concrete block plant is that all the ingredients can come from someplace else, which means it can be set up anywhere, and for the most part the end products are not unique. That means there is no need to ship out the product great distances and customers can source the products locally.
Real clay brick on the other hand is dependent on the color and qualities of the clay and so therefore can be unique. For example I went to Drexel University and most of their purpose built buildings are sheathed with a particular "orange" brick. Its a unique color. Plus not all areas have clays that are suitable for making bricks. Therefore bricks have more opportunities to be shipped.
The concrete products I have seen shipped is pipe, catch basins and prestressed structural components (beams, pilings, floor panels, bridge decks, etc). Products that have unique properties and special value added qualities.

There is a brick and tile works in D'Hanis, TX, on the SP's Sunset Route. The spur was lifted in the eary '80s but it was not uncommon to find 3 or 4 SP double door, exterior post boxcars being loaded in there. d'Hanis Brick Works is registered in the Historic American Engineering Record. Since the town of d'Hanis consists mainly of two very short blocks of businesses facing the track and U.S. Hwy 90, it could be the inspiration for a model. Check it out on Google Earth, street view.
Iowa Interstate RR has a tariff for bricks from De Soto IA to various interchange points. Tarrifs for 50 and 60 foot box cars. The brick yard is actually near Redfield IA and trucked to the De Soto loading point.

There's a masonry supply business in Northern Virginia that still gets bricks and blocks in 50 foot boxcars.
I saw an MP flat with low (4 ft.?) bulkheads and sections of what looked like fence panels in the stake pockets hauling palletized brick in Gulfport MS during 1974. Also, two general service flats loaded with concrete culvert sections. They looked be about three feet in diameter by ten feet long on the C&O in Hampton VA, 1969.
The B&O delivered bricks in boxcars to a dealer in Washington Pa. at least into the late 70's. I think I remember Southern Ry. boxcars being used but I not sure of that.
