This is a recently developed material . It is made with re-pulped paper-fiber with a combination of Portland cement and or clay.
This type of material is considered environmental friendly material.
Paper-Crete is essentially a type of industrial strength paper Mache made with paper and cardboard, sand and Portland cement.
It was discovered by Eric Patterson and Mike McCain.
Relevance:-
Paper-Crete is suitable for making low cost homes with limited longevity and durability.
It is also suitable for making community rooms, sale booths, storage rooms and dwellings for livestock. Paper-Crete can also be used as a plaster.
It can be sprayed on walls to give them good sound and heat insulating properties.
Pros of Paper-Crete:-
Raw materials are very inexpensive and freely available.
Equipment used is relatively low-tech and inexpensive.
Compressive strength of 0.99-1.12 mpa.
It has excellent heat and sound insulating properties.
Paper-Crete is light weight and can be used to make inexpensive roofing alternatives.
Paper-Crete is very workable and can be formed into different shapes such as blocks, panels and sheets with ease.
It does not catch fire easily but smolders for hours.
It is dimensionally very stable.
The more cement and mineral material is used the more fire proof it becomes.
Resist rodent and insect infestation.
R-value is about 2.0 and 3.0 per inch.
Methodology we are Adopting:-
Literature review.
Casting of cubes with different material and with different ratio.
Curing of cubes. {air dry curing}
Testing of the compressive strength.
Permeability test.
Flame test.
Conclusion
SUMMARY OF THE PROJECT:-
During this project we had casted total 12 cubes, i.e. 3 sets. Out of each set 1 cube is kept for oven drying and remaining cubes for air drying.
After casting the cubes we had observed that compressive strength of the oven dried cubes is greater than air dried cubes.
We had also observed that this cube’s fail in shear only.
CONCLUSION:-
From the above results we conclude that density of the paper-crete is less than the ordinary bricks density.
Thus we can use the paper-crete for inner wall construction in place of bricks which has high density, thereby they increase the dead weight of the structure which is reduced by using paper-crete.
