Poor quality concrete kills in Lyari
A group of construction experts are blaming poor concrete production methods for the deaths of more than 30 people in Lyari Pakistan. This is yet another story of crushing devastation from a failed concrete supply chain in the poorest countries of the world.
Concrete should be the focus of international development programs and must not be ignored. Without quality cement-based construction it will be impossible to make reconstruction sustainable in countries like Pakistan and Haiti. People will never feel safe in these building until they have confidence in the concrete that supports and surrounds them.
The news report from Karachi quoted the experts as saying that concrete quality was the probable cause of the collapse of a multi-story building. They suggest that the concrete was probably produced by those who did not have the skill or training to produce the level of quality concrete needed for such a structure.
After studying the remains of the building, the members of the Pakistan Engineering Council (PEC) expressed the need for engineers to be more involved in the production of concrete. This building and the thousand in Haiti testify that allowing the poor to make concrete on the ground with shovels seems to be an international problem.
The Pakistani engineers suggested that mixing machinery, proper water ratios and appropriate cement quantities are the tools that engineers use to create good concrete. They basically echo the issues that CementTrust has been publicizing concerning the production of concrete in poor nations. Too much water, too little cement and poor mixing tools contribute to death and destruction in Pakistan and all around the world.
Another common issue in poor nations like Pakistan and Haiti is the failure in oversight when it comes to concrete construction practices. This must also be fixed as a part of creating a better concrete supply system.
You can read the frustration in these stories from the engineers who witness this destruction time and time again. We join with the engineers in the plea to provide better designs, more training and adequate equipment that will allow concrete construction to become trustworthy in every corner of the world.
