Use of Recycled Plastic Bag Waste in the Concrete

The aim of this study is to e xp lore the possibility of re cycling a plastic bag waste material (BBW) that is now

produced in large quanti ties in the formulation of co ncrete as fine aggregate by substitution of a variabl e

percentage of sand (10, 20, 30 and 40 %). The inf luence of the PBW on th e fresh and hardened st ates properties

of the concrete: workability, bulk density, ultrasonic pulse velocity testing, comp ressive and flexural strength of

the different concretes , has been investigated and a nalyzed in comparison t o the control concre

showed that the use of PBW i mproves the workabilit y and the density, reduces t he compressive strengt h of

concrete contai ning 10 and 20 % of waste by 1 0 to 24 % respectively, w hich have a mechanical s trength

acceptable for lightwei ght materi als, remains always close to reference concrete (made without PBW). The

results of this investigation consolidate the idea of the use of PBW in the field of constructio n, especially in the

The valorization of waste in civil engineering i s an important secto r to the extent that the products to be o btained

are not subjected to ri gorous quality sta ndards too.

The valorization of waste af fects two major impact s, environmental impact is solved by disposing of such waste

and the economic impac t is the use of that in industry or in the field of construct ion, this waste has the advantage

performance in terms of mechanical strength and durability dominate the market of construction materials.

addition of polymeric waste to concrete corresponds to a new perspective in research activities,

Industrial and domestic waste has a significant percentage of polymeric materials in its constitution, which

occupies a considerable volume on landfills. Therefore its recycling is interesting to research and development of

technologies for minimi zing the problems caused by thi s waste.

Several studies have been conducted on the use of plastic waste in concrete. The works of Rebeiz showed that

the resins based on recycled PET can be u

studies have been conduct ed on the use of scrap tire/ru bber in mortar and c oncrete, and a rese arch work has been

2008) . In the other study, Choi et al. (2005) investigated the effect of plastic waste (PET bottles) as aggregate on

properties of concrete. T he results obtained in t his study showed that thes e wastes could reduce the we ight by 2

6% of normal weight co ncrete and the compres sive strength was re duced up to 33% com pared to that of normal

concrete. Sikalidis et al. investigated the utilization of municipal s olid wastes (MSW) for the production

of mortar. Batayneh et work, that the decrease of compressive strength was in

function of increase in t he content plastic conte nt. For a 20% substituti on of sand by the waste, the c ompressive

strength was reduced up to 70% compared to that of nor

Yazoghli - marzouk et al. 2007) have also studied the use of consumed plas tic bottle waste as sa nd

aggregate within com posite materials for building applicati ons. These authors sh owed that t

compressive strength were decreased when the PET aggregates exceeded 50% by volume of sand. Also, It was

found that the addition of pl astic waste (fractions

christians , which is the best way to recycle plastic bags and card Bord which you use every day?

The same way non-Christians do. Where in the Bible is recycling covered? I was not aware they use daluminum back then. Noah could have used this info!
