Study of Influence of Recycled Waste Plastic Bottles (PET) in Concrete Masonry Units
Subject area: Science,Engineering and Technology · Area of research: Structural and Material Engineering
Abstract
In Nigeria, plastic-based products are getting more demand in many industries for packaging. Also, the disposal of plastics is also getting serious and there are still no solutions yet to cope with this matter. The objective of this research is to find an alternative way to cope with this environmental problem. Polyethylene Terephthalates (PET) were used for the production of sandcrete blocks of size 225 x 225 x450 mm. The PET bottles were filled with sand and arranged in the mould vertically and horizontally. This gave rise to two sample types: Vertical Bottle with Sand (VBS), and Horizontal Bottles with Sand (HBS). Eight PET bottles were placed in each block mould to create void in the masonry units. The mix ratio used in this research was 1:6 with water-cement ratio of 0.6. The PET sandcrete blocks were tested for compressive and flexural strength after 7 and 28 days. Thermal conductivity test was also carried out on the PET blocks. Plastic PET blocks gave higher compressive and flexural strength at 7 and 28 days when compared with sandcrete blocks without the PET bottles. It was, however, observed that HBS sandcrete block gave the highest strength and the lowest thermal conductivity. The use of PET bottles in sandcrete blocks will improve the strength and thermal performance of blocks while saving the environment from pollution.
