Why crush brick and concrete?

They are crushing both the brick and concrete from the old MAN building. Why? Usually they use building materials for fill.

Re-use/recycle as aggregate in other materials. A friend of mine is into that area of work and owns many of the kinds of crushers used to process this material. Its well worth doing from what I have seen.
 
Even if they use it for fill crushed will pack better with no voids showing up later. Also used for driveways or on the brick for decorative uses in yards or around buildings.
 
Most State DOT's crush old paving and use it for base material beneath the new paving. Gone are the days of finding a ditch river bank etc to dump old slabs of concrete. They've tried using it in concrete mixes but it was not durable enough and the shear strength wasn't as good as quarried limestone or granite. In the old days they would also push bldg. rubble into the basement and cap it with soil and leave a surprise for the next builder, usually a costly one. gobble
 
A cousin of mine owns an earthmoving company, and has his own crusher. They use the crushed concrete pretty much the same as crushed rock.
 
Old concrete is lousy fill unless it is crushed. Try digging a post hole and hitting that stuff! Been there. Not fun.
 
here they sell crushed asphalt and concrete for a pretty penny,, the contractors who do it get paid to haul it away most times as well,, a real win-win for them

that is better than burying it.
we had a company that wanted to start a crushing plant on some land that county owed. some knuckleheads on the county board
put the big whammy on it.
it would have brought jobs and tax dollars to the county both which would have been good for us.
one board member even threatened to fine a law suit if crushing plant was built.
he was later found to not live in state of IL let alone the local county.
 
Because they will add portland and use it again miles and miles of Interstates are done that way nothing new about that project.
 

Maybe they can sell it for big money..

A bud of mine did well with brick chips till he got into tax issues. What got him was he should have had two separate co's one for hauling and specified the hauling charge and the other for the load of chips. A wholesaler got audited he did not have a sales tax exempt form on file from them he ended up responsible for the sales tax. If he would have charged the hauling separate he would have not had to pay the sales tax on the total invoice... If he would have got a resale tax exempt form from them the sales tax would have been there problem not his.

He let me have all the brick dust I needed brick dust is the finds it makes for a good base for a pad, driveway etc...
 
Gene were they using it as aggregate in the concrete mix or as base material below the concrete. I know they tried some test using it in the mix but in Iowa don't think they ever specified it as a portion of the concrete mix itself. I could be wrong. gobble
 
I can recall 20 some years back, that a type 6 DOT asphalt mix in NYS, recycled aggregate was not allowed. I had a paving outfit pull some crap with an asphalt mix design on a job in Brooklyn NY. They made some kind of deal with the plant. Samples taken proved 2 things, the bituminous asphaltic material was reduced, and the aggregate was recycled materials. Both violated the specification and it cost the foolish contractor. They tried to intimidate us on the job and it became a bitter matter. I never saw such ignorance by a contractor on a job, it cost them into the six figures by the time it was over. On top of that the material arrived below the specified temperature, I personally rejected one complete round of trucks loaded with material. Had I accepted the faulty materials, it would have made me liable.

Ironically, this site was loaded with demolished old buildings and beach type cottages where they were collapse into their foundations, we even found the remains of an old street that was buried when the place was developed into (5) 23 story buildings housing 2200 residents, sometime in the early 60's. Funny, one afternoon we uncovered an old foundation and in a corner on the old intact basement floor was a case of reed wine, old and sour.
 
They built a new Hospital in Angola Indiana. They tore down most of the old one. They brought in a large crushing machine and had different sizes of materials from the crushed brick and concrete that was all used back on site. They had a large magnetic pod on a large crane that removed the conduit and all other metal that was trucked away. They were using large material to fill in as a base for the new drives. Smaller materials were used to raise the grade over a large area. No idea what kind of cost savings came from it but hauling all of it off to a land fill is costly as well.
 
What else would you propose that they do with it Geo? Trucking isn't cheap, why haul out rubble just to haul in fill and crushed stone and pay the trucking twice? Saves a lot of time and fuel. Yes some brick can be salvaged for use but it's generally a very small percentage overall that's economically feasible to save on a large demo project
 
Crushed concrete makes pretty decent road bed. At one time tan old phart in our town had his own crusher; I had him put a couple of loads on my driveway. You had to pick out a few pieces of stray mesh that his magnet missed, but other than that it was great stuff. He sold his crusher and retired, so I tried a load of "crushed concrete" from the local redi-mix plant. That stuff was apparently just waste redi-mix and it was no good at all. Nowadays I use crushed limestone which is a little bit more expensive than crushed concrete but much better.
 
Here in Michigan they setup a whole concrete plant within the cloverleaf of I96 and Grand River. They busted up I96 for miles and hauled all the old cement there. One machine crushed the chunks and separated the rebar. The crushed cement was remixed and put back into the freeway. When they got done they removed everything and reseeded the ground. Now you'd never know it was there.
 
Crushing concrete and asphalt is my business. With the cost of trucking and virgin materials the economics favor crushing and reuse as apposed to dumping it in a hole. It is major business in all of the big cities, to a lessor extent in small towns and rural areas. We process close 500,000 tons a year here in central Ohio, about 2/3 concrete and 1/3 asphalt.
 
Butch,
Never seen crushing brick and concrete is a first for me. I like the idea of finding a second life, reusing, repurposing anything, so I thought this was cool.

It looks to me like they are spending more time crushing the building than it took to knock it down. Also thought the crusher can't be cheap.

North side of town is a place that makes wood mulch out of wood pallets.

St Mary's college on the west side of town uses wood chips to heat the college. City of Terre Haute and others take their wood chips there. They use a gasification process to burn it cleanly.

Why did they put the brick in a different pile. Are they going to sell it as landscaping mulch?

On the north side of town, Menards bought an old concrete business where they make many concrete products they sell. They have acres of damaged concrete products there. They are currently using it as fill. Bet someday they will need someone to crush it. You might want to check on that. geo
 
In iowa it is NOT used in concrete, but recycle asphalt IS used. The product is tested for its oil content and the contractor is paid for the tons and oil. Millings piles are where the profit on a job is made.
 
Brick is less durable than concrete and breaks different, also no metal to separate so easier to do it seperate usually
 
George, A small plant like that will cost around $400,000 and run 100 ton per hour in good material with experienced operator. My plants will run 300 tons per hour and run close to $1,000,000 Finished materials here are around $8 per ton and there is lots of competition for them. We also sell about 5,000 tons of scrap steel that is generated during the processing. The reasons for the brick being separated vary, in most localities including here in Columbus they are considered a contaminant in the finished product, just like wood or plastic etc. The other reason is there is a limited market for crushed brick, mostly landscaping/ornamental rock. Most engineers will not let you bury brick in a fill that has critical applications, such as a building pad or under highly loaded pavements.

We have worked for Menards down in Cincy, If you travel up to Chi-town you will see lots of this. Last time I passed through on 90 I saw 4-5 plants working.
 
The masonry supply company I work for is going "Green" by grinding the "Grog" (reject product) and re-using it in Pavers and Retaining wall products. Nice to see the grog pile go away every couple months instead of waiting till you can't drive around it.

Butch, We have a plant here in Fredericktown that crushes red brick. They mix it with clay and make a topping used on ball diamonds. They are based out of Canada.
 
There is a local crusher that deals with the general public.They operate in a spent gravel pit and take in construction waste,yard waste and fill dirt. They sell compost crushed concrete and a fertilizer product made from drywall and plaster.They charge coming in and going out.I bought several pickup loads of crushed concrete when I made some changes in the barn.I couldn't tell the diference from A gravel except for colour.Made fine concrete too.

We go by a crushing operation at I-70 and Hamilton Rd., by the grain terminal, on the east side of Columbus every day. They always have mountains of the stuff that get made and hauled away. Would that be your place, Butch? Looks like a concrete plant is there too on the Hamilton Rd. side.
 

I would think crushed brick (brick dust the finds) would be a little ruff on yer arse. They do use the finds around the perimeter, for the dirt in the infield its sand-clay are a it would be the base they start out with. For the mounds they use mixture of shale and sand-clay.

Shale not clay its what they make brick out of. They mine it in a open pit its not a rock but has the consistency of a rock and EZ to grind into a powder.

I can dig 30" around here and hit shale I can go south are east 4/5 miles and find sand-clay. Both shale and sand-clay are found in a transition zone were the Piedmont and sand hills blend together.
