Introduction: Concrete Ring Holder
What inspired me?
Well, I love obscure, weird and impractical materials such as concrete while incorporating the material into a project where its features, properties and function isn't required. I love concrete as its such an industrial material and has a very smooth finish.
What will you need?
- Duplex board
- Hot glue
Step 1: Making the Mould
Step one - Making the mould
To make the mould, first grab a sheet of duplex board. When you have this, turn it over so the grey side is facing up. Grab your compass and draw a circle that has a radius of 100mm. When you have this drawn, draw a radius going straight up. After that, draw another about a third of the way around.
When you have something that looks like the pictures, garb a pair of scissors and begin to cut it out. Be careful when you are cutting the tip as this is quite important. Curl the net such that its a cone. Make the circle at least 20mm in diameter.
Using the hot glue gun, begin to secure the net in place. Remember to place a blob of hot glue at the end to ensure the concrete will not pour out.
Step 2: Mixing the Concrete
Step two - Mixing the Concrete
Before you mix in the sand with the cement and water, it's best to mix the cement and the water. First, place the cement mix in the container. Add about 20ml of the water in small intervals, this will allow you to ensure you dont make any errors.
Its now time to add the sand. Never put in all of the water in one go. You will need to add about 100g then stir. Complete this step until the mix becomes like cookie dough. If you add too much or too little you will end up with a weak mix.
Step 3: Pouring the Concrete
Step three - Pouring the concrete
Place some of the concrete bit by bit until 1/4 of the mould is full. Tap gently just to release a few bubbles caught in the bottom. This also helps the concrete spread. Place more of the concrete mix into the mould until it is half full. If there are still gaps, tap the mould on a desk. The concrete needs vibrating before setting as it ensures the mould if definitely covered.
After a day or two, it's ready to remove that mould. Taking off the mould is actually easy, just rip the card and then gently take off the residue from the concrete block.
