What type of plastic can be used in concrete?

Sand-sized Polyethylene Terephthalate (PET) particles derived from recycled plastic bottles provided the best results, achieving the target compressive strength. Using synthetics like plastic in concrete generally weakens the material because they do not bond to the cement mix as well as sand.

What: Waste plastic replacing sand in concrete

Where: University of Bath with Goa Engineering College

A new form of concrete could improve its green credentials by incorporating plastic in the mix. An international team of researchers has swapped sand for waste plastic, making a product that has the potential to cut the material’s carbon emissions and recycle plastic. The research, conducted by the University of Bath in partnership with India’s Goa Engineering College and published in the journal Construction and Building Materials, was prompted by a severe sand shortage in India as the country experiences an unprecedented construction boom. At the same time waste plastic is rarely recycled in India, with as much as 40% ending up in landfill. The study found that by replacing 10 per cent of the sand component of concrete (typically 30 per cent) with finely ground plastic particles, a target compressive strength of 54 MPa was achievable – similar to that of structural concrete and potentially saving around 820 million tonnes of sand per year. Dr Richard Ball, from Bath’s department of architecture and civil engineering, told RIBAJ: ‘This is timely research. Waste plastic is a big problem and people’s awareness of the associated drawbacks is heightened. Putting it into concrete is one possible solution. This work has demonstrated that it warrants further investigation.’ Researchers examined the impact of five finely graded plastics on the structural strength of concrete tubes and cylinders, experimenting with different particle sizes, ratios of sand to concrete, and two different chemical treatments. They tried to strike a balance between adding enough plastic to make a worthwhile impact on sand use while ensuring that the concrete produced was not too weak. Sand-sized Polyethylene Terephthalate (PET) particles derived from recycled plastic bottles provided the best results, achieving the target compressive strength. Using synthetics like plastic in concrete generally weakens the material because they do not bond to the cement mix as well as sand. Properties such as the type of plastic, particle size and shape, and the rheology of the wet mix all have an influence on the strength of the finished concrete.
