Cement Impregnated Canvas
Contents
Basics
- Cloth Canvas that has been Coated/Enfused (AAAAA NEED A WORD) with cement or concrete with only VERY FINE aggregate
- Can go from a dense, yet flexible cloth to a semi structual componet via just water
- The literal "Just Add Water" material
- May present health issues and enviromental issues if not handled/used/disposed of properly
- Main use is temporary structures for Disaster Relief , Refugee Camps , or Construction Material Storage

A fabric/twine 1/4" matrix is printed in rolls and sewn to arbitrary shape. It is coated on one side with PVC (or bioplastic) and then impregnated with a concrete mixture to create thin flexible fabric panels that harden into solid concrete after wetting. Inflation makes for quick prefab buildings. I feel a derivative of such a flexible technology (sans inflation) could be a good pairing for CEB and strawboard for creating roofs and other structural components ... A similar thing could be done with agriculturally derived resins instead of concrete. Something to think about for the long term.
Potential Health Issues
- Main is dust inhalation
- Most likely a non issue, but encourage people all along the use chain to wear at least minor respritory protection as this is essentially cloth coatred with a fine powder
Enviromental Issues
- In using Use Predictive Enviromental Design Considerations you can see that this could lead to increaased concrete use if it were to replace UN Disaster Relief Tents and other similar products
- Unless using Solar Lime Kiln or Charcoal Fueled Lime Kilns this could leave a LARGE Carbon Footprint
- Thus this must be considered in design and use case choices
- Other issues may be water use, as well as potential alkalization and dust pollution of area of use once demolished
- Using a Silt Fence and Dilute and Dispose practtices, as well as taking most rubble/dust gatherd away should help
- Could potentially be reused in either Cement/Concrete Recycling or as a Wave Barrier or Rubble Road
- Yet again consider the Full Product Cycle when designing, and considering the use of these
Research Needed
- How to impregnate canvas and other cloth with cement
- How long it can be stored for
- If it needs to be stored with Dessicants or other Dry Storage Methods , or if this increases shelf life
- Structual Properties Mechanical Stresses simply test samples made in a Universal Test Machine
- Chemical Properties (How it does agains acids and solvnets, may be neccisary in some use cases
- Longevity tests (Make a tent, and check on it on a daily or monthly basis and reccord changes until total structual failure
- How to patch leaks/if they can be patched (Does tape work like it does on canvas, also can cement impregnated canvas sheets be added, and wetted to bond and repair holes
- HOW does it fail? Elastically? Explosively? Small Holes due to Erosion?
- Can it be painted/does paint help
- Does fine aggregate do anything
