final assignment-volcano

In the final assignment, I want to continue with the fluid form, cause I want to develop the uncertainty and changeability of concrete.

At first, I did a small test to find the right supporting material. Pouring the same concrete onto a matte plastic film and a soft plastic bag. Although I know it’s hard to control the shape of fluid concrete, I want to see if it can be affected by material and has a predictable shape.

From the results, we can see too soft material increases the uncertainty of shape and too matte material prevent the flowing of concrete. So at last I chose the harder plastic film and made a pyramid to let the concrete flow down easily.20170426_143100

I simulated the shape of volcano with different layers (different water in every layer).

Firstly I poured down the most fluid concrete (0.200kg) onto the pyramid as the first layer. The concrete went far. After 1 hour, I poured down the less fluid concrete (0.150kg). However, the first layer didn’t dry very well and mixed with the second one. Then I waited another 3 hours and poured down the third concrete (0.100kg). This time it looked with obvious border. Finally I poured down the last concrete (0.050kg) after almost 20 hours.20170428_104057

As a result, I think the final casting looks like a volcano — every layer has an obvious border (except the second one). They come out in different time with different viscosities. We can feel the uncertainty and changeability of fluid concrete. For the future development, I consider we don’t need to do the casting once, but do it by steps to control the whole process.

assignment 5

1.I like the Aalto vase, so make the volume similar to it with the plastic film.

2.When I made the slurry as the recipe, it seemed very dry and cannot pour down at all. So I added more water little by little. Finally the weight was 500 g. And I added 15 g blue pigment.

3.Cause I didn’t find the right aggregate, and didn’t sieved it very well. When I poured the  final slurry, it was just on the surface.

4.The result is it. I think the reason is that the size of the inside aggregate is not coarse enough for the flow of slurry.

Assignment 4 – Impressions and Jigging

Impressions.jpg

Impressions :

After following the concrete mixture given to us, we used a 10×10 mold filled with various sizes of beads to create different dimples on the surface of the concrete. The fabric we used was very thin but didn’t have any stretch in it which might be why the impressions are not as well defined as we would have hoped. The concrete was still very damp feeling when we took it out of the mold two days later but fortunately didn’t crack which is more than can be said for our second cast.

Jigging.jpg

Jigging :

Our second casing method involved jigging and neither of us were super sure of how to do that. We ended up sewing large washers through the fabric and around wooden skewers that were laid across the top of the mold and then poured the concrete over that. We had doubled the amount of concrete we mixed because the mold was twice as large but it ended up being too much and did not sink down and settle as much as we expected it to. Unfortunately, when we went to take it out of the mold, we discovered that it had cracked all the way through on one side. This is probably due to us having had to add water in to the mixture in order to get it to the right consistency as well as the surface tension in the concrete at that point. There is also a very brittle “shell” on the fabric side of the concrete which just crumbles off whenever you touch it.

Concrete traces

Group 9, Assignment 03

We are interested in the pictures on the given assignment papers—-the study of splashes. Cause it’s really intriguing what will happen when we don’t shape the concrete by mould or hand, but just enter different projectiles into amorphous concrete to see the unexpected effects. We choose to use different kinds of projectiles (big/small, plastic/metal, sphere/annulus) and test them with different fluid concretes (with different masses of water).

Picture1

(Except water, we used the basic mix from the assignment.)

Text 1-①, 11:30, 0.100+0.030 kg water

At first, we made the default mix and drilled it for a while, but the degree of fluidity was not enough. Then we added 0.030 kg water and put it in the container cause it was so stiff that hardly flow itself, and we pressed it to flat. When we dropped stuffs, most of them were on the surface of the concrete, even can not leave traces.

Text 2-③, 11:40, 0.130×2=0.260 kg water

To the second experiment, we doubled the water to make it more obvious. But it seemed too fluid this time (almost water-like) that we can pour it to the container easily. When dropping stuffs, many of them submerged to the inside and cannot be seen anymore.

Text 3-②, 11:50, (0.130+0.260)/2=0.195 kg water

To the third experiment, cause we cannot see obvious splashes or traces in the first and third ones (we guessed that water was too little and much respectively), we averaged these two and made water 0.195 kg. And this time, stuffs were half sunk to the concrete but still no splashes.

12:30

In order to observe the traces, we used pinchers to get stuffs out of concrete. Obviously it destroyed the patterns a little. As a wrap-up, the depths of traces differ due to the degree of fluidity, the strength and the height we dropped and the mass of the stuff. But we still don’t know why there are no splashes like the given pictures.

Assignment 2 | Group 9

Assignment2.jpg

Group 9 – Melia Barnes, Wu Yue

Mix 1 :  8 parts Sand

Mix 2 :  0.9 parts Water

Mix 3, 4, 5 :  3.5% Pigment

With the exception of a few miscalculations in the beginning, the casting process went smoothly for us. The first mix turned out more like wet gravel and sand as opposed to concrete, so no matter how many times we hit it against the table it wouldn’t settle smoothly against the bottom. The second mix was obviously too watery but we are hoping that it is able to set enough to take it out of the mold without breaking it.

The third and fourth mixes went well. The concrete turned out really pigmented and when we were finished our hands and the spoon we were mixing with looked like we hand lost a fight with a smurf. However, when we got to the black pigment we discovered that the mix was much dryer than the other colored mixes . We were worried that it wouldn’t set correctly, so we added a very small amount of water to it before pouring it into the mold.

Wood Casting

Wood Casting

Made by: Artificial casting

Process: Casting

Material: Wood and Aluminum

Israeli designer Hilla Shamia uniquely joins the materials of aluminum and wood in this Wood Casting series. Using a whole tree trunk, Shamia pours molten aluminum directly onto the wood, which burns the surface and darkens the wood. The wood gets cut up lengthwise and put into a mold to form the frame and legs of the piece.

Each piece is completely one-of-a-kind due to the various trees used and depending on the “leakage” of the metal throughout the wood cracks. I love the mix of natural wood and the sleek modern metal.

The combination of two contrastive materials and the strange effect interest me most. We can open our mind to consider different materials and methods.

Glacier Cave

Made by: Natural melting

Process: Melting

Material: Glacier

Most glacier caves are started by water running through or under the glacier. This water often originates on the glacier’s surface through melting, entering the ice at a moulin and exiting at the glacier’s snout at base level. Heat transfer from the water can cause sufficient melting to create an air-filled cavity, sometimes aided by solifluction. Air movement can then assist enlargement through melting in summer and sublimation in winter.

Some glacier caves are formed by geothermal heat from volcanic vents or hotsprings beneath the ice.

Some glacier caves are relatively unstable due to melting and glacial motion, and are subject to localized or complete collapse, as well as elimination by glacial retreat.

This is particularly interesting to me because the transformation between water, ice and vapour results in this kind of beautiful scene. And we can think more about the effect of different forms of one material.
