Biodegradable paving

As part of GLAS’ Materials and technology subject at Melbourne University, students designed recipes for different concrete mixes incorporating a variety of types and proportions of organic materials including soil, bark mulch and feathers. Blocks of ‘biocrete’ were mixed and allowed to harden. The blocks of biocrete were then incorporated into the reconstruction of a pond edge. The disintegration of the biocrete was observed over time.
