Garage Update # 3

Stiffy, keep the photos coming, they're great. What are your neighbors unhappy about? Looks good to me. I'd rather have your garage next to me than a couple of gum trees.

Regards.

6" is fine - 2 layers of mesh?

2 layers for slab on ground? Where would the tensile force on the top fibres come from? Usually that is used for suspended slabs and on ground designs with dodgy founding soil or funky loading. Residential garage slabs are usually only one layer. You must be used to the bigger stuff!

One layer of F92 plus the stuff in the footings.

With F92 mesh and 150mm thick that is easily stong enough for your little daytona.. Unless you and Doug are planning on building a semi also?

Stiff,

I did wonder why you had the temp fencing there

Zedn,

Its not unusual to include a 2nd layer of mesh in a 150mm or thicker slab especially if there's no added fibres in the concrete mix.

Yes I am used to the bigger stuff, but similar principles apply.

Stiff,

Good tidy job mate!

plastic shrinkage cracking should be minimal in a 25mpa slab, especially in Melbourne. You are correct that it is not unusual to include a top layer of steel, but that is typical in suspended applications. Top steel is generally designed as per AS3600 where required in tensile zones that exist due to max moments in the top fibres near walls, columns, piles etc. It is also used sometimes to assist with tying stirrups for shear reinforcement and as you say control cracking due to early age, plastic cracks etc.

Sorry for getting technical, i am a civil engineer with a sub major in rehabilitation of concrete structures. I kind of get excited by concrete

Mando,

The neighbours were as nice as pie before I started the project.It took 4 lots of plans for them to reject (the first couple were over the top I must admit) but they didn't want to agree on any of them. Their fruit tree's would be in the shade was the last straw. I then advised the Drafty to design it within the Council Guidlines (with some exceptions from the good neighbour) and they still rejected the plans. I advised them that THIS was within the regulations and it was going ahead. They went to the Council and tried to get the permit revoked. I then had to remove the cement sheeting (some might call it aspestos

and I advised the time and date for this. I also arranged for temp fencing as they have two fantastic dogs (real one's not the daughter) They called the council to complain when the professional removalist arrived. I would need another 5 threads to complete the story but I think you get the drift. It comes down to they lied about their plans to me, they just dont want anyone to develop around them as they have been there for 25 years and they treat it as theirs. It will affect their plans in the future.
We havent spoken since I threatened to build 4 units for drug rehab patients.

PCC,

The garage is on their border for 9 meters.

Zedn,

I am actually quite excited about concrete NOW TOO....

Todays update,
6.30am

There was a bit of rain toda y which delayed the team a bit, but when I left they were full steam ahead. So by PM today there should be a slab.
