Recycle concrete aggregate or Crushed concrete Aggregate concrete is the most common material used for construction around the world.Approximately million tons of concrete debris is domed as construction waste per year.These demolished materials are often dumped on land and are not reused for any purpose this effects the environment and fertility of the land.
Reusing concrete in the form of aggregate would lead to environmental and economic benefits apart from these recycled aggregate has several benefits since they are durable like natural aggregate,versatile can be used for different functions and so on.
To use recycled concrete aggregate for concrete contaminants like reinforcing steel foundation materials soil etc are removed from the concrete debris.It can be done by screening or air separation demolition using electromagnets etc.Then the debris is crushed either manually or mechanically in specified size and quality usually around 20 millimeters to 50 millimeters.
Based on various research it is generally accepted that around 30% of natural crushed coarse aggregate can be replaced with coarse recycled aggregate without significantly affecting any of the properties of the concrete however it is advised to perform the various concrete tests by replacing some part of natural aggregate to determine the perfect proportions of concrete.
Crushed concrete aggregate has a wide variety of uses in the field of the construction industry.The uses are grouped into two categories
1.Unprocessed recycled aggregate
unprocessed recycled aggregates are used for bulk fills riverbank protection base fill for drainage structures aggregate for road construction etc
2.Processed recycled aggregate
The processed recycled aggregates are being utilized for various structural works in bridges pavements used as an aggregate in lean concrete bituminous concrete used in the construction of shoulders median barriers sidewalks curbs and gutters etc
That’s all about crushed concrete.Now we are going to discuss how to make crushed aggregate its preparation.
How we doing when you can probably hear a bit of commotion in the background and that’s because today you look at some concrete brushes all point across the concrete.You take the concrete to speed just a space or I’ll roam while we’re ever broken up card is reheat those days in Big Love thing is where a crusher and I bring it down to make it uniform size probably around four inch or five inch.
you know the recycled material so they can judge event the environment I suppose make people to do the load the large lumps in the crusher it goes into a riddle hover which basically Rosen through it’s all the fine and small Crapo then it goes into the jaw the jaw making crushes it.
It goes off the belt belt Boozer is no verb and magnificent a kitty bits of metal eight take down the way you’re more visible rebar and various bits of metal of nails or less or stuff you know Mornay in the product that makes that’s one side for thick magnet and then will you got you got here pretty product Angela thin that Russia is fat Pamela 3306 that good old reliable unit and I think the later ones without spaniel we are on that and the cat tentacle accident
This is hard stuff you got you can see here you know really big clumps and obviously this is what it goes down to why which is ideal for roadways stuff like that you like we were saying earlier that one there that’s a big magnet and as anything comes up here stone carries on and comes off the end any metal gets picked up chucked off the other side.
Loaded them up the top there the bar make sure that the jaws company called work call capacity I don’t know how many hundreds of tons we put through as are these guys it’s all worth it noisy dusty dirty oh he’s over oh yeah good one a lot of people ask me you know how come you get to see all this sort of stuff well I’ve been around all my life a diet you know I still know a lot of people that are involved in this sort of stuff in construction AG you know so Brown doing it myself.
I can go on see some of my old mates on that and see what they’re up to that’s all good so you know if you like this saw stuff subscribe press the red button doesn’t cost you anything tell your mates tell your pets tell everyone you know anyway much appreciate right that’s a lovely lovely summer’s day and that’s hot so I reckon it’s time for a cup of tea cup of tea and another note nice jam donut anyway thank you all
