In Ghana’s growing construction industry, choosing the right type of concrete can make or break your project’s success. Many builders still ask the same question:
“Should I use ready-mix concrete or mix it myself on-site?”
While both options have their uses, there are major differences in quality, cost-efficiency, and reliability. This guide breaks down the pros and cons of each method — and explains why more contractors are turning to Jobadee Concrete for dependable ready-mix solutions.
What Is Site-Mixed Concrete?
Site-mixed concrete is produced directly at the construction site using cement, sand, aggregates, and water, usually measured manually. It’s common on small projects where space and machinery are limited.
Advantages
✅ Flexibility to adjust mix proportions on-site
✅ Easy for very small-scale or temporary works
✅ No need for large delivery trucks or batching plants
Disadvantages
❌ Inconsistent quality due to manual mixing
❌ Time-consuming process, especially for large projects
❌ Higher labour cost and material wastage
❌ Difficult to control water-cement ratio
❌ No quality testing or batching precision
In Ghana, site-mixing is still used for minor works such as block-laying, driveways, and small foundations — but it’s less efficient for major projects.
What Is Ready-Mix Concrete?
Ready-mix concrete (RMC) is manufactured in a controlled batching plant using computerized systems to ensure accurate proportions of cement, water, and aggregates. It’s then transported to the construction site in transit mixer trucks.
Advantages
✅ Consistent and high-quality mix
✅ Faster project completion
✅ Reduces material waste and labour costs
✅ Tested for strength and slump before delivery
✅ Can include additives for special requirements (e.g. waterproofing, rapid set)
✅ Saves space on-site — no need for piles of sand, cement, or gravel
Disadvantages
❌ Slightly higher upfront cost per m³ (but lower overall project cost)
❌ Requires proper planning to coordinate delivery time
❌ May incur a transport fee if the site is far from the plant

Key Differences Between Ready-Mix and Site-Mixed Concrete
| Feature | Ready-Mix Concrete (Jobadee Concrete) | Site-Mixed Concrete |
|---|---|---|
| Mix Accuracy | Computerized batching system ensures precision | Manual mixing; prone to error |
| Quality Control | Professionally tested before delivery | No testing; inconsistent results |
| Time Efficiency | Quick delivery and pouring | Slower, labour-intensive |
| Labour Cost | Low (handled by supplier) | High (requires extra workers) |
| Material Waste | Minimal | Significant wastage common |
| Durability | High strength, long lifespan | Often weaker and less durable |
| Suitable Projects | Medium to large construction sites | Small or temporary projects |
Why Ready-Mix Concrete Is the Better Choice for Ghana
The shift towards ready-mix concrete in Ghana is driven by three key factors:
- Time Savings:
With tight construction schedules, builders can’t afford delays. Ready-mix from Jobadee arrives exactly when needed, already mixed to specification. - Quality Assurance:
Every batch is tested for slump and compressive strength, guaranteeing that your concrete performs as required. - Cost Efficiency:
Although the initial cost may seem higher, ready-mix reduces labour, waste, and rework — saving money over the entire project.
