Day 1:
Oh mai, need to buy so many items again TT
Here is a list of what we needed for the Creative and Craft tmr:

Lucky us! Someone from class A ordered an entire 8kg bag of cement! It was a lot less expensive than the one from Overjoyed which cost $11! My class only paid 50cents.
We were then briefed about cement and how to mix it.

We started by putting about 2 bowls of cement into the mixing (pail). Then add water in parts while mixing the cement with the rice scoop. The consistency should be like chocolate mud!

More water–>Lighter, Smoother consistency
Less water–>Darker , Rougher consistency

With/without plastic mould lining:
With plastic lining: The cement had a sheen to it and was dryer when it first came out of the mould.
Without plastic lining: The cement was completely matt and was still moist when it came out of the mould. It should be because the cardboard without the plastic lining absorbed moisture and caused the water to be retained in the cement. When the cement is removed, bits of cardboard stuck to the cement.
However after it is left to dry for another 3 hours, it’s colour is that of the cement dried in a mould with plastic lining.

The mould:
Our own mould
We created our mould using cardboard. For simplicity and easy reference I used the net of a cube to create a mould. The first one was made using the net with a shape of..(net cube). The second one is a square surrounded by 4 squares.
The lining is a plastic sheet that is spray mounted on the net. Even when the plastic sheet looks like it is mounted nicely on the cardboard, air bubble forms when the net is folded.
Hence the solution is to cut individual squares out to form the net. This will also facilitate the removal of cement from the mould.

Using plastic cups as mould
The cement in the mould eventually dried and popped out very easily.

Using silicone moulds
I saw from my friend’s end product and my own that silicone moulds tend to produce a sheen to it. Also from using the mould, I learnt to be consistent in my experiment by putting only 2 spoonfuls of cement in each hole.

Time it takes to dry:
Drying time for the cement takes about 1 and a half day.

Other tips:
We can add cement hardener for larger pieces of work.
After placing cement in the mould, we should bang the mould on the table or hit it so that the bubbles can rise to the top and pop. Bubbles in cement will cause it to become more porous when dry.
