Waste Plastic Fibre Reinforced Concrete With Polymers

Another interesting aspect is the thermal conductivity of concrete reinforced with pet fibers.

Waste plastic fibre reinforced concrete with polymers.

In this study domestic waste plastics polythene fibres were used and the properties of concrete viz compressive strength flexural strength split tensile strength are studied. Investigated the recycling potential of glass fibre reinforced plastic waste in concrete and cement composites. Results revealed that the compressive strength of specimens using 5 50 glass fibre reinforced polymers gfrp waste powder under water curing varied from 19 mpa to 37 mpa. Fiber reinforced self compacting concrete frscc is a composite material consisting of cement based matrix with an ordered or random distribution of fiber which can be steel nylon and polythene etc which offers several economical and technical benefits.

The polymer is usually an epoxy vinyl ester. Tuladhar is now working with local concrete producers to find out how to apply the findings more broadly. It was noticed that there is an increment in the thermal insulation of the concrete both adding pieces of different shapes of waste rubber of tires and or plastic fibers strip square and irregular fraternali et al 2011 yesilata et al 2009. They can be added to almost all conventional concrete mixes.

Polypropylene fibre reinforced concrete non structural non structural fibres are not an admixture they are classified as an addition. A blend of waste plastics with mastic components and flooring materials provides floors of more strength especially in industrial units. In order to minimize the problem the proposed. The fibre reinforced plastics or fiber reinforced polymers are a category of composite plastics that specifically use fibre materials not mix with polymer to mechanically enhance the strength and elasticity of plastics.

Concrete mixes incorporating fibres comply with current european and british standards and require no additional specification criteria. In 2009 asokan et al. Fibre reinforced plastic frp also called fiber reinforced polymer or fiber reinforced plastic is a composite material made of a polymer matrix reinforced with fibres the fibres are usually glass in fibreglass carbon in carbon fiber reinforced polymer aramid or basalt rarely other fibres such as paper wood or asbestos have been used. Waste polymers also infuse greater strength when mixed with cement as a reinforced concrete.

Kandasamy and murugesan 2011 used polymer fibres in concrete by weight of cement and reported an increment in compressive strength of 0 68 at 7 d and 5 12 in 28 d. The concrete was reinforced using recycled polypropylene plastic instead and strength and durability tests show that the end result could be used to build footpaths and precast elements such as drainage pits and concrete sleepers. Disposal of plastic waste in an environment is considered to be big hazard due to its very low biodegradability and presence in large quantities.
