3. Introduction Rural Population Cities (with the rapid industrialization) Large amount of construction materials will require buildings for housing and industry, mass transit for moving people and goods, and facilities for handling water and sewage etc The development of new building materials have been promoted by construction activities, shortage of conventional building materials and abundantly available industrial solid wastes

4. Solid waste for land filling

5. 80% emissions of CO2from the construction sector are resulting from Industrial process of Cement, Steel, Bricks and Lime. Direct energy on-site construction Indirect energy material processing, procurement and transportation The primary energy requirement of material manufacture is known as embodied energy. Minimization of the emissions through building can be traced from production of building materials, their procurement and use. The present study aims at comparing the performance of Recycled Paper Pulp-Cement bricks with Burnt clay bricks and fly-ash bricks.

6. Need of Low embodied energy bricks Lot of energy is required for manufacturing of bricks. Manufacturing of burnt clay bricks requires fossil fuel. Manufacturing of Fly Ash bricks requires Fly Ash, Lime & Gypsum Another waste raw material which has been attempted to manufacture lightweight energy efficient brick is the recycled paper pulp sludge from paper industry.

7. Production of Burnt clay bricks

8. Replacing the natural material clay in the brick manufacturing process helps in cutting the emissions to atmosphere. The unburnt carbon present in fly ash bricks helps in increasing the heat while burning the bricks and thus, reducing energy input. In recycled paper pulp bricks energy consumed in burning is totally eliminated. Thus, these materials reduce the total energy input in manufacturing.

9. Experimentation Prefabricated wooden moulds of modular dimension (230x105x80) mm were prepared. The mixes of reduced paper mill sludge and cement with different compositions were prepared. The series of tests were carried out according to ASTM C 67-03a to determine water absorption, specific weight, compressive strength, voidage and equilibrium moisture content.

12. Results Voidage of the light weight brick sample increases with increase in RPMS content. The specific weight of light weight brick is inversely proportional to RPMS% .

13. Equilibrium moisture content of dry light weight brick is directly proportional to RPMS content . The dry compressive strength of light weight brick samples showed excellent compressive strength (35±2 MPa) as compared to conventional burnt clay brick (3±0.5 MPa). .

14. Water absorption is directly proportional to RPMS content. Water absorption increases by almost 100% (by mass) by increasing the RPMS content from 35 to 75% .

16. Comparative Analysis of Physical and Engineering Properties bricks

17. Conclusion The physico-mechanical properties of light weight energy-efficient waste-create brick samples with paper RPMS and cement are investigated. The test results show that the RPMS-cement combination provides results which are of potential to be used in the production of lighter, higher compressive strength and economical new brick material. The observations during the tests showed high energy absorption capacity even beyond the failure load. This composition produces brick which weighs significantly of that of the conventional bricks. The paper-cement bricks are cheaper.
