What is volumetric mix?
Volumetric Concrete (or Mix On Site Concrete) is concrete which is mixed by volume of material, rather than weight. Mobile volumetric mixers provide the flexibility to produce concrete on-site in any quantity without waste. They also produce concrete at any specified slump or water-cement ratio.
How does a concrete mixer work?
A typical concrete mixer uses a revolving drum to mix the components. For smaller volume works, portable concrete mixers are often used so that the concrete can be made at the construction site, giving the workers ample time to use the concrete before it hardens. An alternative to a machine is mixing concrete by hand.
How much does a volumetric mixer hold?
The volumetric mixer varies in capacity size up to 12 m3 and has a production rate around 60m3 an hour depending on the mix design.
What is volumetric concrete used for?
Volumetric: Volumetric concrete is ideal for larger projects given the large truck capacity and the ability to scale the mix up even further. Ready mix: Ready mix concrete is better suited to smaller projects due to the size of the mixers and fixed nature of the mix.
How much does a cement mixer carry?
The normal size of a mixer lorry can carry around 8,100 kilogrammes of concrete. Most mixer trucks have a speed limit of 90 kilometres per hour. See the manufacturer’s website for details of speeds and weights.
What is the purpose of a volumetric concrete mixer?
A volumetric concrete mixer (also known as volumetric mobile mixer) is a mixer on a truck or trailer that contains concrete ingredient materials and water to be mixed at the job site to produce the exact amount of concrete needed.
How long does concrete mixer last?
Do you have to send it back? Yes – According to ASTM C-94, concrete discharge must be complete within 90 minutes of mixing water with cement and aggregates.
How long should you mix concrete in a mixer?
Mix the concrete for about 3-5 minutes, until a uniform, workable consistency is achieved. If additional water is needed, add small amounts of water sparingly.
What does a concrete mixer cost?
While these mixers are new to the market, the level of automation they feature is growing in popularity. So what does a mobile mixer cost? A broad range is $65,000 to $125,000, depending on options.
How much does a volumetric truck cost?
A broad range is $65,000 to $135,000, depending on options, but you also need to consider your return on investment and factors such as parts availability, how long the company has been in business and their industry reputation.
Is volumetric concrete good?
What is a volumetric concrete mixer?
A volumetric concrete mixer (also known as mobile mixer or volumetric mobile mixer) is a mixer mounted on a truck or trailer that contains separate compartments for sand, stone, cement and water. Materials are mixed on a job site to produce the exact amount of concrete needed.
Is 2020 proall volumetric concrete mixer unused?
2020 ProAll Volumetric Concrete Mixer Unused! Mobile or volumetric mixers offer many advantages for the delivery of concrete that conventional ready-mix drum mixers cannot offer.
What are the advantages of mobile mixers?
Mobile or volumetric mixers offer many advantages for the delivery of concrete that conventional ready-mix drum mixers cannot offer. With mobile mixers, the required ingredients of sand, stone, water and cement are stored on the machine in separate bins and compartments as opposed to being pre-mixed at a concrete batch plant.
What is a mobile concrete mixer?
Mobile mixers all but eliminate waste and overruns by producing only what is needed at the job site and can adjust “on-the-fly” if more or less concrete is required. Unmixed materials can remain stored on the truck so they are not wasted.
