Concrete is a building material made from fine and coarse materials bound together with cement. To make concrete from limestone cement, gather tools and materials, such as a rigid tray, a hoe, and a few hand tools. The general rule for concrete is two parts sand, four parts gravel/crushed stone, and one part cement. The mix depends on the project type and can be ready-mix concrete (RMC) or a concrete mix.
To make your own concrete from limestone cement, mix 2 parts all-purpose sand to 1 part cement in a wheelbarrow with a shovel or in a cement mixture. Mix in 4 parts water. The standard concrete mix consists of 1 part cement, 2 parts sand, and 3 parts gravel. Getting the correct ratio of these materials is crucial for a successful concrete project.
In the UK, a basic, general purpose concrete mix is made up of a 1:2:3 ratio with 1 part cement, 2 parts sand, and 3 parts stone. To make your own concrete, mix sand into a bucket or wheelbarrow with a large surface area, then add Portland cement a few scoops at a time.

WE HAD A MASSIVE DRIVEWAY POUR IN THE FRONTYARD THIS DAY WHICH IS WHY THERE WAS SO MANY GUYS* In this …
I tried it. It was cheap and more importantly I could control the timing of a Sunday evening job. 3-4 yard driveway extension. 10×20′,4-5 inch, $150 bagged Portland, free sand, $80 rock, $100 home depot gas powered towable mixer, $(350 total) (as opposed to $800 truck),,trailer of materials, 2 guys and a shovel. Alot of work 5 hours. We were 1 guy short..-couldn’t mix fast enough,,, Shoveled in 3 2 1 mix. Sprayed water hose in at a fixed count. It came out OK but quality of concrete vastly inferior to truck delivered. Triple the work. I had hard time with consistency. It looked great when I troweled and broomed… For 6 months.. First freeze-horror show… some spots were pure sand- i could scratch away with my boot.. I hit it with Quickrete concrete resurfacer which I love. Fixed it perfect for a couple months.. Delaminated. Not resurfacers fault,,, sandy spots just weren’t solid. Anyway, as long as I resurface each spring it’s great, pretty easy 4 hour project each year but I just say “heads up”. If you can order $800 delivered truck it’s worth it. I’ll probably try again if timing convenience dictates but next time I’ll double the Portland,, and mix longer/more consistently,,should be better,…probably,,, maybe,, DieHard Do-it-yourselfers unite!!!
You want to add water a little at a time as you are mixing it. You need to keep the water down to a minimum amount. It depends on the application of the concrete, the amount of moisture in the gravel and sand. You want to mix it so that it will work into the formwork and fill all of the voids. To do that you can use a concert vibrator or tap the forms with a hammer or a piece of lumber to remove air pockets. One other thing is to use torpedo sand for structural applications. You can use masons sand for a finer finish for a floor. Also for exterior applications you want to use gravel that is chert free. Chert is dust that moisture is holding it to the gravel. So if you were to pour an exterior slab, you could ask your supplier you want the gravel to be chert free. Or if you are mixing something small you could simply wash the chert off the gravel by hand. What the chert does is it retains moisture and during a freeze thaw cycle it will force the topping to spall. It also deters the cement from bonding to the gravel. Its also good to some the gravel down before mixing. Very dry gravel in dry and warm conditions will cause the concrete to shrink at a fast rate. During these condition it helps to wet cure the concrete. It involves keeping the concrete wet during a period of time till the concrete reaches a specific psi.
Thanks foe the article, it’s very helpful to me, a home owner trying to do stuff by my own. About the comments, wow, I knew the “experts” and PhD in concrete would make bad coments.. common, if you’re an expert, why are perusal a how to article meant for beginners? If you know the “right” way to do it, make your own article and upload it, although be careful with the comments from experts.
80lbs bag of 4000psi is $4, even cheaper in bulk. Want it even stronger? Buy chopped fiber online and mix in your own glass. If you are pouring something large, ordering with a concrete co is still going to be cheaper than mixing your own from raw (assuming nyou even have the ability to mix enough at a time to get it all in the same pour).
Where can you find these items I’m trying to build a underground places a secret place and I looked up u need cement for the walls and floor and roof I dont know what I’m doing and I cant have anyone know or it’s not a secret anymore so I need your help is there anything that you can find outside to make cement or something strong I could use to build with Pls help me out I beg ya😓😢
