In this material experiment, I worked with three different canvas patterns and three different cement formulas to examine what how they would form to the different patterns. I wanted the concrete to have a “plush” or fabric texture. Due to the viscosity the canvas has left a texture. and the darts and cut outs draw the material in and give the concrete an organic shape. The process of making these moulds was making the canvas pattern and than attaching the fabric an armature that uses gravity to help move the concrete. I filled the concrete while using a vibrating tool, then left the pieces to cure with a wet cloth and sealed in a plastic bag. Overall my process was successful, I would have like some of the gaps to be filled and would have made more functional stabilizers when pouring the concrete as the concrete become very heavy. The most optimal concrete formula for this form was; 2 Portland, 6 Sand, 1 Fondue, and Resin in 2400 ml water.
