| dc.description.abstract | Rapid industrial development causes serious problem all over the world such as
depletion of natural aggregates and creates enormous amount of waste material from
construction and demolition activities. Quantities of polymer wastes also have been
increased these recent years due to the boost in industrialization and the rapid
improvement in the standard of living. In Malaysia, most of polymer wastes is
abandoned and not recycled. This situation causes serious problems such as wastage of
natural resources and environmental pollution. Polymer products such as synthetic
fibers, plastics and rubber belong to petrochemical compound and not easily
biodegradable even after a long period. One of the ways to reduce this problem is to
utilize waste materials in the production of concrete. Use of these materials not only
helps in getting them utilize in cement, sand, aggregate, concrete and other construction
materials, it helps in reducing the cost of concrete manufacturing, but also has numerous
indirect benefits such as reduction in land-fill cost, saving in energy and protecting the
environment from possible pollution effects. An experimental research is made on the
utilization of plastic waste, High Density Polyethylene (HDPE) as coarse aggregates in
concrete with a percentage replacement of 10 %, 20 % and 30 %. The laboratory tests
include slump test, compressive strength and water absorption were conducted in this
research. The samples content 10 % of High Density Polyethylene (HDPE) has better
performance in term of strength and the samples content 30 % High Density
Polyethylene (HDPE) has a good resistance to water absorption. | en_US |
