How much water is needed to mix the concrete? If I break that down to a cubic meter of concrete it equals: What is the concrete mix ratio of 20MPa concrete?Ģ0MPa concrete is equivalent to a 3000 psi concrete mix, so the ratio is the same as above: I have a lot of experience and knowledge with mixing ratios and I have access to many professionals in the business that may be able to help you with your specific needs. If I break the weights down per yard of concrete it comes to:Ī sack or "bag" of cement weighs 94 pounds so this tells us a 3000 psi concrete mix is also equal to a 5.5 sack mix of concrete.ĩ4 pounds x 5.5 bags of cement = 517 pounds (pretty close to 510.75)įor more 1 on 1 help with concrete mixing ratios, join The Concrete Underground where I can help you with your specific questions through my private forum. Rounded off it's basically a 1 : 3 : 3 mix ratio THIS GIVES YOU A BASIC 3000 PSI CONCRETE MIX RATIO OF: On the ticket you can see the actual weight of 8 yards of concrete: Water reducer is used to help make the concrete mix more workable without adding water to the mix.
It also shows the air-entrainment (Master-air) and a water reducer (Master Glenium).Īir-entrainment is used in climates that have freeze & thaw cycles to help keep the concrete from scaling.
On the bottom of the ticket it shows you the actual weight of cement, sand, aggregate, and water. The concrete batch plant ticket you see below is for an 8 yard load of concrete. See me explain this page in the video below! What is the concrete mix ratio for 3000 psi concrete (also 20MPa concrete) We use the 4 mix designs shown above for most of our projects. My company pours concrete almost every day of the work week. I'm going to show you the actual batch plant ticket they give me when the concrete trucks show up on the job and we pour the concrete. These concrete mix ratios for 3000, 3500, 4000, and 4500 psi concrete come from the ready mix concrete company I use to pour concrete floors, slabs, patios, pool decks, and stamped concrete. These are actual concrete mix ratios for 3000, 3500, 4000, and 4500 psi concrete
