Abstract:
The amount of waste has increased year by year and the disposal
becomes serious problem. Particularly, recycling EVA waste in life and
industry is low.
This study presents a simple way of recycling EVA waste in the field of
civil engineering as constituent in mix of light weight concrete, and to
evaluate its efficiency to produce a concrete with high strength and
lightweight .Also this work aim to study of permeability, sound insulation
property for concrete samples with different densities. Experimental study
was carried out by preparing different test samples using various
proportions of EVA waste (10%, 25%, 40%, 55%, and 70%) in the mix and
a blank sample of concrete of grade M25. Samples and Blank were cured in
water tanks for 7 days and 28 days. Resulted samples were then tested for
compressive strength of concrete and slump value, and then the results were
compared with the normal conventional concrete. Results showed that
using10% EVA gave the best performance. Accordingly it was concluded
that there is an indirect relationships between the amount of the EVA in the
mix and the weight of the product. Same relation was notices against
compressive strength.
An empirical formula to determine the sound insulation of this concrete
blocks by using the UPV, The sound insulation of concrete blocks
calculated according to a proposed empirical formula made in this work.
Finally the results of permeability decrease with increase in replacement
percentage of EVA waste compared with the normal conventional concrete,
Results showed that using 10% EVA gave the lowest permeability and the
best performance. Results of sound insulation showed transmission losses
~ V ~
increased with decreased the average weight per area unit for concrete
mixtures. Accordingly it was concluded that there is an indirect
relationships between the amount of the EVA in the mix and the sound
insulation of the product. Same relation was notices against compressive
strength . Study is recommended. to use of industrial EVA waste as
replacement of aggregate is better for non loads structure members for
examples light weight blocks ,tiles and interlock ,also EVA waste can be
used in thermal and water insulation, sound insulation as studio, halls of
universities, conference hall , schools.
