Concrete blocks are often made of 1:3:6 concrete with a maximum size aggregate of 10mm or a cement-sand mixture with a ratio of 1:7, 1:8 or 1:9. These mixtures, if properly cured, give concrete blocks a compression strength well above what is required in a one-storey building.

DIY Cinder Block Bench
One of our annual family traditions is to chop up our Christmas tree after the new year and have a bon fire in our backyard with some S’mores and hot cocoa. We have a patio in our backyard with a steel fire pit that is perfect to host this tradition, but this space has always lacked seating for all of us.

To mix the concrete you should spread the sand out on a concrete slab or a steel plate. The sand must be 5cm to 10cm thick. Spread the cement over the sand and add aggregates.
What type of cement is used to make concrete?
The cement used to make concrete bricks must be strength class 42,5N or higher, as the concrete needs to cure as fast as possible. Sand and stones will form the aggregates for the concrete bricks. You can use pit or fine river sand, coarse sand (up to 5mm in size) or stones that are no bigger than 10mm for hollow bricks or 13mm for solid bricks. Usually, you can make concrete bricks with just coarse sand, but a combination of aggregates can also be used.
How to store cement and aggregate?
Keep aggregates and cement dry and separate until you need to mix them. Ideally, bags of cement should be stored in a dry room. You’ll need space to produce and store the concrete bricks and blocks. A flat concrete slab will be perfect. You will be able to store 1000 bricks or 200 blocks for curing and drying on a space of about 50 square metres.
How to test if concrete is strong?
For each ratio or combination, mix a batch of concrete with water and use the brick moulding machine to make some test bricks. This way, you can find the perfect mixture for your needs. The heavier the freshly moulded brick, the better. Knock the dried bricks together to test their strength. If you hear a hollow thud, it means the bricks may be weak. If you hear a ringing sound, it means that your bricks are strong.
How many bricks can you make with cement and aggregate?
If you use an aggregate to cement ratio of 8:1 with three-and-a-half bags of cement and a cubic metre of aggregates, you will produce enough concrete mixture to make about 400 bricks. This number can vary depending on the size of the bricks and whether the bricks are hollow or solid.

Basics of Building A Cinder Block Or Concrete Wall
When to Build A Cinder Block Or Concrete Block Wall
- Digging the trench for the cinder block wall's concrete footing and curing the mortar are the only weather-dependent parts of this project. If the ground is frozen, you will not be able to dig by hand, and extreme cold can affect the curing process of the mortar. Otherwise, the wall can be built at any time of year, in nearly any condition.
Estimating Number of Blocks
- Calculate the necessary cinder blocks by square feet. The typical cinder block is 8 by 16 inches, meaning that a cinder block covers an area of 1.125 square feet. The total cinder blocks needed will be 1.125 times the area of the wall, but be sure to subtract the openings such as windows, doors or any other architectural feature. The wall area is calculated by height times its length. Re…
Permits and Codes
- Free-standing concrete block walls may require permitting. Check with your local building department to determine if a permit is required. Even if the wall is exempt from permitting in your area, it may still require zoning approval. Check with your local planning department for zoning requirements.
Safety Considerations
- Working with masonry materials is labor-intensive, so take frequent breaks and stay hydrated. Keep your back straight and use your legs when lifting. Wear heavy-duty gloves when handling the concrete blocks. When pouring mortar or concrete or for any other activity that creates dust, wear breathing protection. Consult a structural engineer to design the footing including where to insta…
