Should concrete blocks be filled

How to fill a cement block with concrete

Whenever you work with concrete blocks, you can greatly strengthen them by pouring them into concrete. Cement blocks are cheaper to work with than concrete in home construction projects, but they are not as strong. You can make up the difference by spending a little more reinforcing the blocks, a project that is still cheaper than using fully poured concrete.

This is something that is not difficult to do and will strengthen your concrete blocks considerably. You may also find that concrete can help with cracked concrete. However, you should use caution when working with cracked cinder blocks as the process for doing this can be difficult.

Step 1 - do the math

Find out how much concrete you will need for your concrete blocks. While it doesn't take much to fill them completely, the amount of concrete you will need will obviously have a lot to do with the number of blocks you have. A single bag should go a long way in most projects, but for a more accurate estimate, measure the length, width, and depth of the holes in your block. This will give you an approximate calculation of how many cubic feet of concrete can be filled per block.

Step 2 - drilling

It's a good idea to start your project by drilling the holes in the concrete blocks if there aren't any holes already. You need to make sure that you are using a hammer drill for this task as any other type of drill you use will not be able to do the job properly. Trying to use a regular drill bit could damage it or even the cinder block. Make sure you proceed with a 12 inch drill bit; This is the best size considering what you are doing. After these holes are drilled, you can measure the approximate volume using a procedure similar to the first step, adapted to cylindrical holes.

Step 3 - Prepare Concrete

It is a good idea to wait for the concrete to finish until you are ready to use it. Be sure to read the directions on the packaging of your product so you know you are getting it right. Each type or brand can have slightly different directions.

Pour the required amount of water along with the amount of the mixture you are going to use. Typically, a five-gallon bucket or even a wheelbarrow will suffice for a mixing container. Use your cement mixer until the material has been properly stirred. Then you are ready to begin.

Step 4 - pouring concrete

You pour the concrete into the holes, either pre-existing or ones that you have drilled. However, if you are going to use the concrete to repair cracks, you will need to add rebar to the other side of the crack to tie everything together. Once the concrete has been successfully poured into the concrete block, you need to give it time to dry completely.
