TESTING EARTHQUAKE DEBRIS IN PORT-AU-PRINCE

  • Published on September 5, 2022

The overall objective was to investigate the possibility for converting debris into materials for vertical construction, specifically housing Create value chains for debris removal and housing delivery suited for small and/or informal businesses. This project will create value chains for debris removal and housing delivery in Haiti after the earthquake 2010. There was massive debris after the earthquake and at the same time scarcity of suitable sand and gravel. The underlying idea was to investigate to what extent the debris included cement and lime that had not reacted when originally cast and how much they could be reactivated and add to the quality of future cement based products if used in concrete. 

The project did not achieve much, by the time the study had passed through the bureaucracy the debris was contaminated with all type of garbage and human waste.....it was dumped into the sea and landfills. UNDP commissioned the study, EcoSur network implemented it with specialists from the Cuban Institute "CIDEM". Conclusions of teh study include:

1 - The debris can be recycled as aggregate for manufacturing concrete, it is recommend to use water-reducing admixtures. It can be used as masonry mortar

2 - The debris is a good alternative for the manufacture of items such as micro-concrete tiles and ferrocement panels.

3 - The debris can be used in ordinary structural concrete with a characteristic strength of 20.0 MPa.

This case study is directly related to the work of the OPN SBC programme.
