Concrete mixing ratios and quantities

Cheers all for your replies.
It was just a strip foundation for a greenhouse. All done this morning mixed in a mixer DIY style. All done in 3 hours.
It might have been quicker having a readymix lorry, but it was good being able to go at our own pace. It’s hardly got to withstand a lot of weight so exact mixing ratios didn’t matter.
In the end my mix was half a bag of cement, 4 shovels of sand and 8 of gravel per mix.
25 loads later, all done 👍🏽

Good....well done.
Not rocket science but you do need a even mix.

Glad your all sorted

No truck mixer or, plasticisers, super plasticisers, reinforcing, steel or steel fibres or Poly fibres, retarders or accelerators or cement to water ratios? You will never get an even design mix out of a half bag mixer and you wouldn't believe the cement that goes in a cube of say 30N mix, some 350kgs/M

Nor any high grade Browning's were harmed in this greenhouse base pour......... :rofl: :rofl:

Used a batching mixer a lot with the electric operated clutch/winch to drag the skid bucket to a hopper that fed a big mixer. great tool for local work on fencing or floor screed on extensions...Knock it up damp and off you went to the job in the tipper. Cement was 1cwt bags in those day that made the legs strong lol

Drop one of those in the boot of an old car and they were bu$$ers to get out
 
Wheelbarrows, the nightmare of all rotational mixer drivers. Some companies wont do it unless you pre-book. Volumetric mixes are the nightmare of future purchasers...
 
We use to have comps who could push the most in a barrow...all good until it went over lol
Those lovely big barrows with the wheel right out the front so you had most of the weight or that's how it felt anyway.
On one job the bloke on the mixer thought it funny to keep filling my barrow to the top as I was the lad to see if I could push it.
An old labourer on the job said next time he dos that let it go over in his wellies, I did he stopped.

No this was a skid like a drag line bucket with a bridle on the front running to a winch and a power cable on a switch which engaged the clutch and dragged the skid up the pile to the hopper.. good fun but you had to be ready to let go lol

Yes mate a batch mixer. I was referring to your " who could push the most in a barrow" comment.
 
Large pour multiple loads, very restricted access or you cant get the lorry close to the work, add in a nice stiff slump or quiet a few columns to pour now that's a diffrent ball game.
Now with all due respect what I know about hedge laying is very very limited but I have been in this industry for more than 40 years starting as a apprentice carpenter and ending
up as a senior site manager for one of the biggest civil and building companies in the country.
Each tool or piece of plant has to be chosen by its merits for each specific job.
Bit patronising mate. I lay hedges in the winter but I'm gold card carrying bricklayer the rest of the time and I've been doing it for 30 years. I've built more houses, extensions and commercial units than I care to remember, and run sites for contractors. I've built four bedroom houses single handed, excluding chippying and plastering, from founds to setting the flashings on the chimney stacks. Before that, for some crime in a previous life, I served time on big civils outfits, including concreting gangs.
I quit big site work long since because a. it's detestable, b. frequently poorly run by people with no personnel skills who can't coordinate multiple trades and c. usually doesn't pay anywhere near as much as people claim it does.
I haven't got the company Vauxhall, the unmarked rigger boots and Matalan tie of the managerial set, just time served on the tools and years of applied best practice in running jobs smoothly and cleanly single handed.
The guy's doing some concreting at home, not casting the Hoover dam.

No intention of patronising you but I will clarify how I stand to the description of a site manager
A. Your welcome to your opinion
B. I would hope my results and custom/client satisfaction show my jobs are not poorly run
C. I would hope I have reasonable personal skills and am able to coordinate multiple trades.
I dont have a Vauxhall I have a Hilux truck which I own
I normally wear mucky old wellies onsite and dealers in the office.
The only clothing I wear at work from Matalan is boxers and socks.
The tie when worn is a nice dark blue with a small company logo.

I to am time served got the indentures and City and Guides. Years of working on similar jobs to your self and carrying out similar roles.

I did know he wasn't building the Hoover dams as that has been completed for quiet awhile now 😁

Hope you have a nice weekend
