Abstract

The production of paving block from sand and cement is becoming of immense and popular in Nigeria and is being used as finishing material in landscaping. Presently the cost of cement is becoming high and polythene waste is increasing daily causing pollution all over the land. This project researched into recycling of the polyethene and using it as binding agent in the production of paving blocks.

The pure water sachet nylon was collected, washed and dried. It was cut and melted in a machine fabricated to recycled the sachet water nylon. The recyclate was collected and mixed with sand at different temperature range of 200 – 300 OC. The condensate was mixed with sand poured in a mould and allowed to cool. Compression and hardness test were performed on the paving block produced.

The result shows that increase in temperature increases the compressive test of pave block and the more the content of the sand the higher the compressive strength of the paving block. The hardness test revealed that the pave block produced at 300 OC has a higher value than that at 200 OC while the pave block with higher sand content has greater hardness value.
