yes I am
I would be worried then. If it cracks, or does not stand up to punishment, its going to annoy you and be a problem.
doesnt sound like the right mix to me. Too lean

If you're using the concrete as a wearing surface, a P200 is not a particularly good mix for this purpose. The strength is not going to be much above 10 N/mm2 (look at the Mix Proportions table in the Prescribed Mixes section on the main site).
It would be OK as a shed base (not sure what you told the supplier when you ordered it) but as a wearing surface for a workshop floor, it may dust up in time with foot traffic etc. Can you live with that? Looking at your shuttering, the depth of concrete seems to be about 100 mm or possibly a bit more. Provided you've got a well compacted base, the slab is unlikely to crack unless the perimeter load is excessive - I don't believe you deepened the edges to form an edge footing?
Dusting can be minimised with a dust proof surface hardener - usually sodium silicate which you can be purchased at builders merchants (Sika, Cementone etc). It's not bullet proof but it does help.

well it will have one o these buildings on it https://www.quick-garden.co.uk/best-de....uk.html so I suppose most of the load will be on the edge did tell them it was for a workshop floor and its 150mm thick

The workshop doesn't look excessively heavy, however, according to the manufacturer, they provide a concrete base laying service. If you've not done it already, I suggest you call them to get their opinion. They may say it's OK just as a slab without edge footings / no reinforcement.
If it is OK (with them knowing it's a P200 (about 10 N/mm2 - possibly 15 N/mm2 max), I'd still recommend you apply a dust proof surface hardener (make sure the slab is cleaned of mud, crap etc). It's not expensive and quite easy to apply with a broom and bucket (follow the manufacturers instructions).

ps a P200 is definitely not suitable as a wearing surface for a workshop floor!!!!

Kinda changes things. It was always described as a base not a floor.dig dug dan wrote:Are you using the slab as the finished floor in your workshop?

This workshop base seems to have turned out an epic saga. What's wrong with just 4-5" of strong mix concrete poured. Maybe some expansion brackets.. or or am I over simplifying things?
I mean thats what my garage floor is and I've got a power cage in there which I do deadlifts in and throw 20kg plates around left right and centre with no damage whatsoever.

Couldn't tell you mate. I only just started doing them again cos I stopped out of fear for my back but they just can't be replaced for increased power. I've never done a 1 rep max test either but I'm currently repping 100kgs at 8-10 and it absolutely destroys me to the point I feel I'm gonna pass out or vomit or both. My max is 130 for reps, dunno what that'd make my 1 rep max prolly around 160-170 but I was only 180lb at 6ft at that time so well in amateur level just nothing special.

190kg was a 1 off at aged 33 5'10" and 14 stone
I avoid deadlifts now as it aint good for your joints same with squatting
used to bench 130 for 3 but just do 3 sets of 12 with 80 now
good fun when you get into exercise
