    Abstract:

    This article is closed access, it was published in the journal, Construction and Building Materials [© Elsevier]. The definitive version is available at: http://www.sciencedirect.com/science/article/pii/S0950061809003547comprehensive laboratory experiments were conducted to improve the mechanical properties of Glass fibre reinforced Plastic (GRP) waste powder filled concrete using superPlasticiser for widening the scope for GRP waste recycling for different applications. It is imperative to note that the 28 days mean compressive strength of concrete specimens developed with 5–15% GRP waste powder using 2% superPlasticiser resulted 70.25 ± 1.43–65.21 ± 0.6 N/mm2 which is about 45% higher than that of without the addition of superPlasticiser (with GRP waste) and about 11% higher than that of the control concrete (without GRP waste) with 2% superPlasticiser. The tensile splitting strength of the concrete showed 4.12 ± 0.05–4.22 ± 0.03 N/mm2 with 5–15% GRP waste powder which is also higher than that of the control concrete (3.85 ± 0.02 N/mm2). The drying shrinkage, initial surface absorption and density of GRP waste filled concrete were evaluated and found better than the desirable quality for use in structural and non-structural applications

  • assessing the recycling potential of Glass fibre reinforced Plastic waste in concrete and cement composites
    Journal of Cleaner Production, 2009
    Co-Authors: Parthasarathi Asokan, Mohamed Osmani, Andrew D F Price
    Abstract:

    At present Glass fibre reinforced Plastic (GRP) waste recycling worldwide is very limited due to its intrinsic thermoset properties, lack of characterisation data and non availability of viable recycling and recovery routes. In the present study, efforts were made to recycle GRP waste powder and fibre in concrete and cement composites and assess its quality to comply with the British standards for use in construction applications. Results revealed that the mean compressive strength of concrete composites using 5%–50% GRP waste powder under water curing varied from 37 N/mm2 to 19 N/mm2. Increase in the concentration of GRP waste decreased the compressive strength. However, increase in curing duration (14–180 days) resulted in improving the compressive strength of concrete with 5% GRP application to 45.75 N/mm2. Moreover, the density of concrete with 50% GRP waste was reduced by about 12% as compared to the control sample. The bending strength in terms of modules of rupture (MOR) of 12 mm thickness cement composites developed using 5% GRP waste fibre attained 16.5 N/mm2. The findings of this work pave the way for further GRP waste recycling in precast construction products for use in various applications.

  • Study of glulam beams pre-stressed with pultruded GRP
    Computers & Structures, 2005
    Co-Authors: Zhongwei Guan, P. D. Rodd, D. J. Pope
    Abstract:

    Improvement of the load carrying capacity of glulam beams by the addition of reinforcement is now common practice. Recently it has been demonstrated that pre-stressing of beams using pultruded Glass fibre reinforced Plastic (GRP) tendons provides an available alternative due to the compatibility of the two materials and the low losses of pre-stress. This paper describes a finite element based model which was validated against test results and then used to investigate bond stress between a pre-stressed GRP tendon and the adjacent timber. Parametric studies were also undertaken to evaluate the effects of tendon thickness, beam span and the pre-tension force on the structural behaviour of beams.
