Concrete Mixing Ratios - How To Make Concrete (Cement, Sand ...
The less water you use to mix the concrete (somewhat dry but workable) the stronger the concrete mix. Accurate concrete mixing ratios can be achieved by measuring the dry materials using buckets or some other kind of measuring device. By measuring the cement, stone, and sand, you will have a consistent concrete mix throughout your entire project.

How Cement Mixers Work | HowStuffWorks
This technology has been largely replaced by the use of augers and fins. Inside a traditional batch mixer is a concentric series of fins with a slight corkscrew pattern. The direction of the drum's spin squishes the wet concrete into the back of the mixer.
The Technology | CarbonCure Technologies Inc.
The CarbonCure Valve Box is connected to the CO₂ tank stored onsite, and automatically injects a precise dosage of CO₂ into the concrete during mixing. The CarbonCure Control Box syncs with the plant’s batching software, so adding CO₂ to a mix is as easy and quick as flipping a switch.
Concrete Batching Control Systems from ACT
Whether you're running one concrete batch plant or a combination of multiple concrete mixers and producing blocks, pavers, pipe, utility, architectural precast, ready-mix or job-site production, our WCS Control Systems are simple to use and comprehensive to meet your concrete production requirements.
Advanced Concrete Technology Training - BMC
Course Objectives . This course will provide engineers, architects, technologists and field inspectors with a comprehensive understanding of modern concrete technology, covering all aspects from mixture design, to transporting, to handling, to curing to field control tests and on-site performance.
Quality of Water used for Concrete Mixes-Concrete Technology
Use of Sea Water for Mixing Concrete Mixes. Seawater contains a small quantity of sodium and potassium salt.The salinity of seawater is 3.5 percent.These salt can be reacted with reactive aggregate and alkali cement. Therefore sea water should not be used for the mixing of concrete if the aggregate is potentially reactive.
CarbonCure Technologies | From Carbon to Simply Better Concrete
CarbonCure manufactures a technology that introduces recycled CO₂ into fresh concrete to reduce its carbon footprint without compromising performance. Once injected, the CO₂ undergoes a mineralization process and becomes permanently embedded, improving the concrete’s performance.
Mixing Concrete – Hand & Machine mixing of concrete materials
The time of mixing concrete materials in the mixer and the speed of mixer are very important factors in deciding the strength of concrete which is formed. The mixing time should be rotated at a speed as recommended by the manufactures of the mixer. The concrete discharged by the mixer, after thoroughly mixing concrete materials, should be ...

BSI is a new concrete technology that has a much higher tensile and flexural (bending) strength than standard concrete. It is a fiber-reinforced concrete that is combined with premixed dry components. It is much denser than standard concrete and structures built with it will need far less new concrete, perhaps as much as 80% less.

You will require cement, sand, gravel, and water for making the concrete mix. Put the cement, sand, and gravel in the container at a ratio of 1:2:3. Start mixing water in the container and stir the mixture continuously with a rod. Pour water until the concrete mixture become pliable enough to pour in the mold.
Correct Ratios for Concrete Mixes
I do have tables for trial concrete mixes but they only go up to 40 MPa. According to Fulton’s Concrete Technology published by the CCI, which has a chapter on concrete mix design (maybe there’s a copy in your school library?), high-performance concrete with a 28-day compressive strength of 68,9 MPa = high strength concrete.
