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.
10. recycled paper pulp bricks samples
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.
