Could this then be pushing the proverbial uphill?

Dust mask Bob don't wont to hear you are suffering hardening of the lungs/concrete lung syndrome look what happened to that woman who was injected with the stuff to get a bigger ass

Ray, you have too much time on your hands

Hi Bob,
The degree of difficulty between breaking up old concrete with reinforcing in compared to without reo is quite marked isn't it?
Makes you realise the importence of always using mesh regardless of the perceived importance of the project.
I helped a friend break up an old slab a few years ago and it contained chook mesh and even that was a PITA.
I wouldn't worry about picking up the crumbly bits as you go, once you've picked out the big bits get your garden rake and rake them into a heap and shovel them up.
Thats one of the things I'm good at, dishing out advice.

Regards,
Geoff.

Yea I know a bit about reo. I worked 4 summers as a builders labourer on high rise buildings when I was a student in the 1970s. I spent most of my time on a pneumatic jack hammer taking out beams and columns that were put in the wrong place so I know something about demolition with reinforcing. The biggest beam I helped take out was a 1 m x 1 m x 10 m long beam in a basement of a 25 storey building. It had reobar in in that was about 1.5" thick. Boy was that a awful job - bugger all safety and OHS. The scaffold we were on was 4 m high with no sides, no ear muffs, and I wore a wet rag across my nose and mouth by way of a dust mask. It took 2 of us a week to bring it down and I remember coming out of the basement every day looking like one of those white mud men you see on National Geographic channel. The basement was stinking hot because the plumbers were firing up the oxy every now and then to cut the reobar.

Yep

That does sound like the way to go

Well - the old shed floor is gorne!

I started at 7:30 am and got rid of the last few bits and pieces still cluttering up the old floor. Nephew arrived at 8:30, I was on sledge hammer and he was on barrow and we swapped over every few loads.

It was supposed to be 36º but it seemed a tad warmer than that inside the old shed but we finished at about 12:30.

Still a bit of small stuff to pick up but never did a full skip and a bare shed floor look so good.

Now for a few advil and a long nap.

Hi Bob,

Crikey mate, it was a stinker here today. I sat in a shopping centre, drank coffee and read the paper. Well somebody has to balance out the hard workers like you two.

That last bit of concrete in the bin looks like it is half a slab and weighs a ton. I think I will have to have a beer just thinking about doing all that in 36 degrees.

Well done.

Cheers

Nice for some I agree we sure earned our keep today.

Yeah that was the final piece which we decided to leave in one piece - should have got you around to give us a hand with that

Its actually surprising what can be done with a bit of hard yakka.

As kids we often went to the local gravel pit with dad and his workmate ( who had a tip truck - bloody rotten old belly lift Austin man killer ) and helped to shovel 5 yards of gravel into the truck. All the concrete at home was done by mixing in batches in a hand mixer! No mesh was ever used and that stuphph is still in place after more than 50 years of hard use.

We built a solid concrete ramp up to the garage/ shed. It was 600mm thick at the shad end. When dad decided to move the shed down the back of the yard and expand its capacity the ramp ( no reo ) was demolished with 14pound hammer and crowbar.

5 metres of concrete here was barrowed from the front fence in less than 20 min. The same crew did 10 metres in two 5m loads, each taking just over 20 mins. Extra time was the extra wheeling distance.

Couldn't do it now, because.......... (write your own ending )

Hi Bob,

Yes, sure, any time, just give me a call. Unfortunately the mobile reception in my local coffee shop is really, really bad. Terrible shame that.

Keep up the good work.

If photos tell a story, the old floor under the concrete looks pretty good with a bit of scrabbling to be a sound base for the new floor!!

I raked it up already but I can see why the old floor slumped - there was the remains of a lot of dead dry organic matter mixed in with the dirt under the old pad. I think it broke down and lost bulk which is why it slumped. Anyway, it should be OK now.


I also took the opportunity to install a 150 mm exhaust duct from the wall to the middle of the floor where the TS with router side table will be located. I also installed some 50 mm PVC under the floor through which I can run an extension cord - so no cords across the floor either.

TS is where the TS will sit over the 150 mm "middle of the floor" ducting.
Bench B will be replaced by a much narrower bench to allow for better access.
PP will be another 15 A powerpoint from which an extension cord will run into the 50 mm pipe under the floor to the TS/router.
The red arrow shows where the ducting will run up the wall and connect up with the rest of the ducting.

Thought I would throw my 2 cent in the ring
The pvc pipe under the concrete is a great idea I all ways put it in even if I have no use for it now I usually do latter. Take a photo to remember where it I have put them.
With your ducting pipe I would make sure you can access the pipe at each end above the concrete in case it blocks up, it being the low point.

Yeah I wish I had put a few ducts into the floor of the new part of the shed but at least I managed to get this one in.

Good point. I will add some access points where the ducting goes into and comes out of the concrete.

When I dismantled my old 100 mm ducting system I noticed that all the flat sections had quite a lot of saw dust (~10 mm deep ) in bottom of the duct. The worst was was the flat section just before a section of vertical duct where up to 25 mm of dust had accumulated. What I effectively had was a 75 mm ducting system. No wonder my system was performing so poorly.

My guess as to what happens is this. If the DC is pulling a lot of sawdust and it picks up a rag or bunch of shavings which suddenly blocks/reduces the airflow, the sawdust traveling in the pipe behind the blockage cannot be carried along by the air flow and just drops out of the air stream to the bottom of the duct. The sawdust in the long vertical duct falls to the bottom and is where the greatest blockage can occur. When the air flow resumes it will not be fast enough to pick the sawdust up from the bottom of the ducting. Adding some access points will enable me to insert a compressor hose down the pipe so that I can fluff up the dust that has been settled on the bottom of the

BTW Ivan the concretor has just been and done his stuff so the new floor in the old shed is done! I have 4 weeks holidays starting next week so I should be able to get stuck into the insulating and lining of teh old part of the shed..
