Texture // Concrete Bonding to Printed Form
Concrete Form-work
We designed a form-work structure that could be used for several test pours. It consists of:
WE WILL ATTACH A DIGITAL FILE OF THE FORM-WORK
- -Plywood Base - or any flat surface
- -8 pieces of 3/4" plywood for bracing and panel attachment
- -four pieces of 1/4" plywood - used as wall panels
- Use a nail gun to fasten the 3/4" pieces to the 1/4" plywood.
- There will be a short side and a long side.
- The Short side will take into consideration the adjacent 1/4" plywood dimension. (Corner detail 1)
- The long side will take into consideration the adjacent 3/4" plywood dimension. (Corner detail 2)
- At the corners, drill holes so that the panels can be braced to one another. (This will create easy fastening and removal)
- Base will also be drilled so that it can be fastened to the 3/4" pieces.

Testing Concrete Stress Under Normal Conditions :
"A displacement controlled test is possible using a machine with a servo valve, in a closed loop. As shown in the schematic diagram in Figure 5, the machine compresses the concrete specimen at a constant displacement rate of the specimen – the LVDT on the specimen provides feedback to the controller, which then indicates to the servo valve the degree of piston movement to be provided (to keep the specimen displacement constant). In this way, the load response of the specimen is continuously studied as it undergoes incremental displacements. Failure occurs when the cracks in the specimen grow to an ‘unstable’ size."

Electronics : Pressure Pad - 3/xx/2020
The use of pressure sensors would allow us to mimic an actual pressure test. The approach is economic in the sense that it can be constructed anywhere with very cheap components. The data collected from the pressure sensors would be constant, allowing us to "hypothetically" track the stress load on concrete cubes. Additionally, if there were to be any breaks internally, the sensors would be able to track the pressure change.
