What Is Ready Mix Concrete?
Ready mix concrete is a pre‑mixed construction material made by combining cement, aggregates, sand, water, and, where required, specialised additives. In contrast to concrete that is made by hand on the site, ready-mixed cement is made in a controlled setting and then delivered onto the site of construction, ready to use immediately.
In the UK Ready-mix concrete is generally prepared at an industrial plant for batching, in which all the components are precisely measured prior to loading onto delivery vans. The delivery vehicles that are used typically include:
- Drum mixer trucks, or
- Mixer trucks that are volumetric, in which concrete is mixed in a fresh manner at the time of its arrival
This controlled procedure guarantees consistency, reliability and conformity with British Standards, something that is a lot more difficult to achieve using traditional mixing techniques.
In the UK construction industry, the use of ready-mixed concrete has been deemed the most reliable choice for structural construction because it is a reliable strength material with uniform performance and a consistent conformity with the building regulations.
Ready Mix Concrete vs Site‑Mixed Concrete
One of the most important decisions when planning a concrete project is choosing between ready-mix concrete and site‑mixed concrete.
What Is Site‑Mixed Concrete?
Site‑mixed concrete is made by manually mixing cement, sand, aggregate, and water on the construction site, often using small mixers or hand tools. While this method may seem cost‑effective for very small jobs, it comes with several drawbacks.
It is possible to have a myriad of issues that result from mixing websites like:
- Inconsistent mix ratios
- Poor quality and inconsistent strength. Quality control
- Very large amounts of material waste
- Longer labour duration
- Greater risk of structural issues
It is crucial to take into account mistakes made by humans when combining web pages, especially when it comes to large or complex projects.
Why Ready Mix Concrete Is Different
This risk is mitigated by batching plants that make exact measurements as well as controlled procedures. Every batch is created according to precise specifications, and it is ready to be put in place on the day of delivery.
Key differences include:
- Performance and strength that is consistent
- Faster project timelines
- Reduction of waste
- Conformity in line with UK construction regulations
For projects that go beyond simple DIY tasks Ready-mix concrete is the most efficient, safest and reliable option.

How Ready Mix Concrete Is Made at a Batching Plant
The quality of ready-mixed concrete begins at the batching plant.
The Batching Process Explained
In a batching facility, the ingredients needed to make concrete are kept in silos or designated areas. The materials used to make concrete comprise:
- Cement
- Sand
- Coarse aggregates
- Water
- Enhancers (such as water-proofing agents)
Each ingredient is meticulously weighed or measured in accordance with the concrete grade required and specifications.
The material is then placed in a drum mixer truck or sorted for the use of a volumetric mixer truck dependent on the delivery method.
Drum Mixer vs Volumetric Mixer Trucks
Drum mixer trucks:
Concrete is fully mixed at the batching plant and kept rotating during transport to prevent setting.
Volumetric mixer trucks:
Materials remain separate until arrival on site, where the concrete is mixed fresh as needed. This method allows:
- Exact quantities to be produced
- Last‑minute adjustments
- Minimal waste
Volumetric concrete is particularly popular for domestic and commercial sites where flexibility is essential.
Why Controlled Mixing Matters
Controlled batching ensures:
- Uniform strength
- Consistent workability
- Reliable curing performance
This level of quality control is extremely difficult to achieve with site‑mixed concrete and is one of the main reasons ready-mix concrete dominates the UK construction industry.
Because batching plants operate under strict quality control systems, every mix is traceable and produced to a defined standard. This is particularly important for UK projects, where consistency and compliance play a key role in meeting structural and safety requirements.
Types of Ready Mix Concrete in the UK
There are several types of ready-mix concrete, each designed to suit specific applications.
Standard Ready Mix Concrete
Concrete that is standard ready-mixed can be used to:
- Foundations
- Slabs
- Driveways
- Structural applications
It is typically offered in grades that range between C10 and C40 according to the load requirements.
Volumetric Ready Mix Concrete
The concrete mix is created on the spot using specially designed mixer trucks. They also offer:
- Precise quantities
- No wasted material
- Greater control over timing
This is a great option for projects where precise volumes aren’t known. Concrete that is volumetric ready mix is particularly popular for UK residential properties, as access is limited, and project amounts can be difficult to estimate prior to the project’s completion.
Specialised Ready Mix Concrete
Specialist mixes include:
- Waterproof concrete
- Fibre-reinforced concrete
- Screed
- Rapid-setting concrete
Mixes are typically employed in basements, flooring systems, industrial or commercial constructions that require higher performance.
Concrete Grades Explained and Their Uses
Making the right choice of concrete grade is among the most important choices in any construction venture, and it’s an area where professional guidance is able to prevent costly errors.
Common UK Concrete Grades and Applications
C10 / C15
- Kerbs
- Pathways
- Non-structural work
C20
- Foundations for domestic use
- Shed bases
- Garage slabs
C25
- Driveways
- House extensions
- Light commercial projects
C30 / C35
- Industrial flooring
- High-traffic zones
C40
- Applications for heavy-load and structural applications
A mistake in the grade could result in breaking, weakness in the structure or even long-term failure. Professional advice is highly recommended.

Benefits of Ready Mix Concrete Over Alternatives
Ready-mix concrete has a number of advantages over site-mixed and bagged concrete, which makes it the ideal option for the latest UK construction projects.
Consistent Quality and Strength
Ready-mix concrete can be created with precise measurements at an industrial plant that ensures that every batch meets the specifications. This ensures consistency and lowers the risk of cracks, weak spots or uneven performance, which could occur when mixing on-site.
Faster Delivery and Efficient Placement
Since ready-mix concrete arrives at the site in a state of readiness and is ready for use, it can save valuable time in construction. Its speedier placement results in fewer delays, smoother scheduling and increased productivity, which is especially crucial for large or time-sensitive projects.
Reduced Labour and Site Disruption
There is no need for mixing on the spot; there are fewer people required to help prepare the food, which can keep the site cleaner and more organised. This is particularly helpful in residential areas where space is limited, and disturbances must be minimised.
Minimal Material Waste
Volumetric ready-mix concrete allows the exact amount required to be produced on site. This avoids leftover materials, reduces disposal costs, and supports more environmentally responsible construction practices.
Improved Structural Reliability
Ready mix concrete is designed to meet specific load‑bearing and performance requirements. When matched to the correct grade, it delivers long‑lasting durability and structural integrity for both domestic and commercial applications.

Common Ready Mix Concrete Mistakes and How to Avoid Them
Even though ready-mix concrete offers consistency and reliability, problems can still occur when planning or preparation is overlooked. Based on real‑world experience across domestic and commercial projects, these are the most common mistakes seen on UK construction sites, and how to avoid them.
Ordering the Wrong Quantity
One of the most frequent issues is ordering either too much or too little concrete. Over‑ordering leads to unnecessary waste and additional costs, while under‑ordering can cause delays, cold joints, and compromised structural integrity.
How to avoid it:
Use volumetric ready mix concrete where possible, or work closely with your supplier to calculate volumes accurately based on depth, area, and site conditions.
Choosing the Wrong Concrete Grade
Selecting an incorrect concrete grade is a serious error that can affect strength, durability, and safety. A weaker grade may not support the intended load, while an unnecessarily strong mix can increase costs without benefit.
How to avoid it:
Always consult your concrete supplier about load requirements, exposure conditions, and intended use to ensure the correct grade is specified.
Poor Site Preparation
Even the highest‑quality ready-mix concrete can underperform if the site is not properly prepared. Restricted access, poorly built formwork, or delays during placement can all impact the final result.
How to avoid it:
Sufficient access must be provided to delivery vehicles, formwork must be built in advance, and concrete must be placed without delay.
How Long Does Ready Mix Concrete Take to Dry and Cure?
Concrete continues to cure after placement and continues to get stronger as long as there is a sufficient amount of moisture present to carry on the chemical reactions. There are many factors that determine how strong the concrete will become and how fast that will happen.
Initial Setting Time
After placement, ready-mix concrete will set anywhere from a few hours to 24 hours.
- Light foot traffic is usually possible after about 1 to 2 days.
Preventing moisture loss and protecting the surface from rapid temperature changes will help the surface cure properly.
Full Curing Time
Concrete may look like it’s ready to take on the world, but that bravado is a facade.
- Most mix designs will achieve maximum strength after about 28 days of curing.
Across the UK, moisture and cool temperatures have an impact on the cure speed as well, and require the most care.
