How I did it!

Illustrated descriptions of hands-on make experiments done for the development of the Concrete Hydram


The format for reporting hands-on technical experiments is described here. This what should result:
A form of reporting that makes people with a technical mind set enthusiast and invites participation
A form of reporting that can later easily be transferred into a manual
A form of reporting that closely resembles the way Demotech publishes 'See it' and 'Make It'
A form of reporting that is inspiring for Appropedia
A form of reporting that gives a good presentation of all the experiments that have been conducted on this issue

Description of the layout of this page and how to upload picts
Go in a few moments to , click 'edit' and study the make up of the page. Note the following in this line with tags to attach and display a picture with a caption:
%rframe%Attach:D038_070625Exp1Tiles1.jpg | [--Parts to cast disk from candle wax/clay mix-]
%rframe%Attach: stands for a picture that is uploaded with the command 'Attach:' or the paperclip. It makes this picture move to the right side.
Then there is the line [--Parts to cast disk from candle wax/clay mix--] This is the text that can be added as a caption under the picture. Study all details of this example closely, such as the tag for double smaller fonds in the caption and copy it or vary it when presenting a picture differently.
Ok, there we go. ... And more text that is here removed. However limited to what fits next to the picture.
Do not end this paragraph with the usual '\\'. but with the stronger working '[[<<]]'

Hands-on experiments related to the Concrete Hydram



Attach:D038_StripDripTryOutOverview.jpg Δ | First experiment with strip drip irrigation Name: Strip drip irrigation and water transport development
Target: to get an idea of the strip drip irrigation system; to transport water cheap and efficient and to irrigate tranquilly
Done where and by whom: San Juan la Laguna, Guatemala by Bram de Vries
Degree of success on scale 1 to 10: 6 Sufficient. Slow water supply, good transport. Missing: better support for a straight hose. Holes tempt to close. Not suitable for e.g. union.
Based on info from: Name mail, document or source.



Attach:D038_TileSandProtoStarting.jpg Δ | Molds on flat sand to rapidly make thin tiles Name: Thin insert tile development
Target: to remove the wooden board out of the process of tile production and to ease making the reinforcement
Done where, when and by whom: San Juan la Laguna, Guatemala, 070707, Bram de Vries
Degree of success on scale 1 to 10: Yet unknown
Based on info from: Name mail, document or source.



Attach:D038_MakingWaxRingWithWoodenRing.jpg Δ | Other method of making wax rings Name: Making the wax ring with the wooden pipe connector ring
Target: to make the wax ring with no extra tools
Done where and by whom: San Juan la Laguna, Guatemala, by Bram de Vries
Degree of success on scale 1 to 10: 8 Good: fast, easy, less chance for mistakes
Based on info from: Name mail, document or source.



Attach:D038_070822Brokenrings.jpg Δ | Broken rings Name: Broken rings and wood selection
Target: to realize that not all wood types are suitable
Done where and by whom: San Juan la Laguna, Guatemala by Bram de Vries
Degree of success on scale 1 to 10: 7 All three rings broke, with other wood not. Missing: a knowledge base of wood types
Based on info from: Name mail, document or source.



Attach:D038_070625Exp1Tiles1.jpg Δ | Parts to cast disk from candle wax clay mix Name: Thin insert tile development
Target: to make insert tiles thinner and produce them more effective to achieve an accurate fit for the wooden ring connectors
Done where and by whom: Maastricht Demotech Lab, by Reinder
Degree of success on scale 1 to 10: 7 Good Fast, thin, steel 'hair', Missing: easy removal of wax core
Based on info from: Name mail, document or source.



Attach:D038_TileProductionOnWoodAndPlasticWedgeMoldOverview.jpg Δ | Mold with sheet metal for impulse valve tile Name: Tile Production on wood and plastic with sheet metal wedge mold
Target:

  • to replicate the method using bicycle spokes on planed wood that is covered with plastic
  • to replace the difficult to remove wooden wedge with a sheet metal mold

Done where and by whom: San Juan la Laguna, Guatemala by Bram de Vries
Degree of success on scale 1 to 10: 7 Good. Flat enough surface, well to do, good reinforcement distribution. Missing: better air removal, holes in impulse valve tile can leak concrete juice.
Based on info from: Name mail, document or source.



Attach:D038_070625Exp1Tiles1.jpg Δ | 8 words description of picture Name of project: Give describing name and link this name to the relating page.
Target: target to be achieved in the experiment
Done where and by whom: Location and name of person(s)
Success on scale 1 to 10: # Good: 10 words, Still Missing: 10 words
Based on info from: Name mail, document or source.
