Making Brick from Concrete 14 September 2015
In the beginning of making concrete bricks has been for wall coverings over the years, but they can be used for decorative purposes as well. Making the common brick has been molded from clay and fired in a oven. That isn’t the only way you can make brick. Another way, popular with do it yourself types, has been by using concrete. You can make your own bricks from concrete manually following the next steps.
The forms you need to use for the concrete bricks. That requires basic carpenter tools and a sheet of 20 mm. for your brick dimensions.
The strips will be layed on a flat level area and spread plastic sheeting over it to keep the concrete from bonding with the plastic. The work area will need to be left undisturbed for at least 24 hours.
Place the assembled side form on top of the 20 cm plastic covered plywood strip. Either nail the side forms to the plywood or drive wooden stakes around the sides of the forms to keep the forms from shifting off of the plywood bottom strips.
Produce the concrete and pour it into the assembled molds. That will most likely be the most physically challenging part of making brick from concrete. Using a commercially prepared dry mix of concrete materials is the easiest method.
Fill the wheelbarrow with concrete
Make a small hole in the middle of the dry mix using a shovel or a common garden hoe.
Add small amounts of water in that small hole, preferably from a bucket rather than a hose for better control of the amount of water that is added at any one time.
Batch the dry material and water together with the hoe or shovel, adding water until you have a concrete consistency that is workable. Too wet and it will want to push up the side and run under the forms.
Too dry and it will not want to consolidate, but rather it will leave air voids in your concrete brick blocks.
Tap on the side of the forms with the brick forms filled. Tapping on the top afterward will force any trapped air out from inside of the concrete.
Bring it to the drying area for 24 hours.
