Efficient bricks for govt projects proposed
/ BL – 12 March 2021
Extract :
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.
Singh also said that India will
overachieve on the country’s voluntary commitment under the Paris Agreement to
raise the share of non-fossil fuel sources in the national electricity
generation capacity to 40 per cent.
“Share of non-fossil fuels in our power
capacity is already at 38 per cent today. It will reach 60-65 per cent by
2030,” Singh said. “We are the only country who will achieve its pledges under
the Paris Agreement.”

3D printed plastic beams are stronger than steel
Lightweight 3D-Printed Lego-Like Beams Are Just as Strong as Concrete / Interesting Engineering / 11 Mar
Extract :
Researchers have developed and patented a
new 3D-printed beam that assembles in a similar way to lego pieces, and is much
less heavy than traditional concrete or metallic beams.
The team from the Universitat
Polytècnica de València (UPV) in Spain, explains that its beams
use recycled plastic
as the raw material, can be printed and assembled in situ thanks to their
3D-printing nature, and weigh up to 80 percent less than regular reinforcement beams.
After three years in the making, all in
all, these new beams appear to be more sustainable, lighter, easier to
assemble and transport than concrete or metallic beams, which could change the tides in
the construction industry.
"It is a very intelligent natural system and its reproduction in these beams awards them, with the low structural weight, very high mechanical capabilities," says José Ramón Albiol, [ joalib1@ csa.upv.es ] one of the researchers of the study.
The main novelty of the beams lies in its
polymeric profile, which enables the pieces to be
assembled, linked, and concreted wherever needed. There are no metallic
components to the beams, which means they don't corrode with time.
Even though the beams' weight isn't as
heavy as concrete beams, they still maintain their structural rigidity, explains Albiol.
The way the researchers managed to
minimize the weight so drastically was by using an alveolar structure, a
natural system that can be found in human bones, and which was the inspiration
for the structure.
On top of all that, as they're 3D-printable,
the beams are more easily customizable nearer the construction site, which also simplifies
transportation and lowers costs.
"To be able to customize the beams
in situ makes it possible to adapt the characteristics of each of them to the
structural needs at each point of construction," mentions Miguel Sánchez, from the Department
of Systems and Computer Science (DISCA) of the UPV.
The team patented its creation in October
last year, and it'll be interesting to see how the construction world
integrates and welcomes these beams.
