Concrete aggregate

I have just written an essay on the mass demolition of concrete prefab council estates country wide regarding the discarding of invested energy and material that goes into constructing such estates. For example 3 football pitches full of waste would have accrued if the Park Hill estate (1000 flats) in Sheffield had not been decidedly redeveloped of recent, wasting 3 weeks continuous output from a power station. So with 1.0 to 1.2 million tonnes of demolition waste amassing annually, this project was a rather welcome find. Singaporean designers have developed a process to recycle aggregate concrete into various applications, further contributing to a more sustainable built environment.  

I am very keen to start experimenting with concrete as a material and have seemingly be saying so for too long, I must act. Concrete, though controversial, its possibly my most favorite, quite a statement but due to its emotionally received complexity: volatile, looming, intimidating, masculine, dominating, beautiful, cool, calm, straight talking, purposeful, austere, ugly, harsh and foreboding.
