- 1. MEL203 MANUFACTURING with NON-METALLIC MATERIALS INDIAN INSTITUTE OF TECHNOLOGY ROPAR [INDIA] PROJECT REPORT TOPIC PAPERCRETE BY MANISH ANAND [P2009ME1103] NARKHEDE SHRIDHAR WASUDEO [P2009ME1077]
- 2. Introduction • Papercrete is a recently developed construction material which consists of re- pulped paper fibre with Portland cement or clay . • Paper + concrete=Papercrete • Discovered by Eric Patterson and Mike McCain in year 1928.
- 3. Make papercrete • Making papercrete is simple and easy • Use volatile sources – Water + waste paper + portland cement[binder] Tow mixture Add water upto2/3rd height
- 4. Tow mixture contents sharp blade • to chop paper and to mix • Rate of rotation determine rate of mixture production Collect waste papers
- 5. Put in tank paper + portland cement After running the tow mixture for four to five minute at moderate speed Must look like this
- 6. Pour into gang mold from bottom exit of tow mixture Level it equally
- 7. Wait for 20-30 minutes so that excess water can drain out After 3-4 four sunny day Source : snapshots from “DIY How to Make Papercrete in a Tow-Mixer – YouTube”
- 8. • Sample data 6000 liters of water +35 kg paper + 40 kg Portland cement Takes 3 days To produce 40 block of size 12 in X 8 in X 5 in Source: ” DIY How to Make Papercrete in a Tow-Mixer – YouTube”
- 10. Properties Papercrete Concrete Wood • Compressive Strength • Compressive • Compressive – 0.1 MPa -1.2 MPa strength – 60MPa – High but less than concrete – 50 MPa – Much higher • Tensile strength – Much higher • Tensile Strength – Very low • Tensile Strength – 1.9 MPa • R-value – 3 MPa – Resistance to heat flow • R-value • R-value – 1.25/inch – 2-3/inch – 1 -2/inch • Seven times lighter than concrete
- 11. Other properties of Papercrete • Sound absorption properties • Papercrete blocks are lightweight, less than a third of the weight of a comparably-sized adobe brick. • Mold Resistance • Flame retardant – does not catch fire easily but smoulders for hours. • Fungus retardant • Lighter than concrete
- 12. Fire test Papercrete vs Wood
- 13. Screenshots from video “Papercrete Flame Test – YouTube” Less spread and damage in papercrete as compared with wood
- 14. Insulation Test We can place our hand for longer time as it is anon conductor
- 15. Temperature v/s Distance Graph Three samples- prepared in accordance with the requirements of the ASTM C1061 1986.
- 16. Temperature vs Time of Heating
- 17. Impact Energy Test Impact Tester MT 3016 machine Specimen Specifications 10mm x 10mm x 70mm Height of release of Average fracture toughness of hammer=450 mm Papercrete=1.12 J Conventional Mortar=0.24J
- 18. Applications and limitations • Large use in house building • Used as sound and heat insulator • Different shapes to decorate houses , flower pots • Large number of shape which generate large area of constructions. • As it is lightweight it could be used in various applications. • Limitations – Building made from this could be only of one story. – Rainy or marshy area are not suited.
- 20. Advantage of papercrete • Environmentally friendly-one of the major component is paper lading into the landfills. By using paper in buildings we can significantly decrease the amount of paper landing in the landfills. • Everyone can make with little knowledge • Lightweight but strong. • Easy to use • Insulating • Low cost
- 21. Disadvantages of papercrete • As of 2007, papercrete lacks approval from the International Code Council. • Papercrete is not particularly ‘structural’, which means it can’t be used over doors and windows without some additional support – either wood or traditional concrete. • Another disadvantage is that it absorbs water.so we have to protect it from water in the rainy season. • The cost of raw paper will increase as the number of people using the papercrete will increase.
- 22. Future • Trying to reduce the amount of concrete required to prepare the papercrete with same strength and also ultimately reduce CO2 amount. • Decrease in the carbon footprint of the house. • Use of different materials at the place of cement such as gypsum and lime. • sustainable construction materials, decorating materials and etc. • Large market in Africa , India , China [because people has less money]
- 23. Conclusions • Good choice to utilize waste paper. • Big market India, China, Africa. • Good choice for one story building. • Inner walls of house can be made by papercrete. • No govt. approval-but can be used. • Increase in demand may lead to deforestation.
