Hi Friends,

Even as I launch this today ( my 80th Birthday ), I realize that there is yet so much to say and do. There is just no time to look back, no time to wonder,"Will anyone read these pages?"

How about Energy Efficient Cement Concrete ?

 


Background :

 

Last year, Shri R K Singhji ( Minister for  Renewable Energy ) proposed an ENERGY EFFICIENT BRICK

Ministry is proposing that all government-funded construction projects use bricks certified as energy efficient, Minister of State (Independent Charge) for Power and New & Renewable Energy RK Singh said on Friday.

Under a new scheme being implemented by the Bureau of Energy Efficiency, fired clay brick manufacturers, who lower energy use during their manufacturing process, will be labelled as ‘Energy Efficient Enterprises(E3)’

“It should take around three years for brick manufacturers to implement these energy efficiency reforms, after which we have proposed that any government-funded project such as the Pradhan Mantri Awas Yojana use only E3-certified bricks,” Singh said at the launch event for the scheme.

Dear Shri Singhji,

I urge you to contact Dr. Behzad Nematollahi of Centre for Smart Infrastructure and Digital Construction, csidc@swinburne.edu.au at Swinburne University of Technology in Melbourne , for its development of ENERGY EFFICIENT CONCRETE [ b.nematollahi@sheffield.ac.uk ]

 

    Bendable, Green, and Cement-Free Concrete Created to Better Withstand Earthquakes

      ( Interesting Engineering  / 05 March 2020 )

Extract :

The product is a major improvement on conventional concrete that is not only very rigid but also very polluting. Traditional concrete shatters when being stretched or bent and has a high carbon footprint due to the calcination of limestone to produce its key ingredient, cement.


“Production of this novel concrete requires about 36% less energy and emits up to 76% less carbon dioxide as compared to conventional bendable concrete made of cement,” said Dr. Nematollahi.


The novel material is made of industrial waste products such as fly ash, a by-product of coal-fired power stations. The researchers have also included short polymeric fibers in order to ensure that the concrete can bend but not break.


This makes it ideal for use in areas where natural disasters such as earthquakes are common. “Building in areas vulnerable to that sort of natural disaster is one of the main uses that we can see for this material,” Dr. Nematollahi added.


“Our laboratory test results showed that this novel concrete is about 400-times more bendable than normal concrete, yet has similar strength.”


This is not only great news for disaster-prone areas, but it also great for the environment
