Recycle concrete to protect environment,EZ RENDA stucco machine also support this
attitude
Why can't we recycle concrete from our deteriorating infrastructure for use as material in new
buildings and bridges? It's a question that a team of researchers at the University of Notre Dame is
examining.
"While concrete is the most commonly used construction material on earth, it is also the biggest in
terms of environmental impact," said Yahya "Gino" Kurama, a professor of civil and environmental
engineering and earth sciences, who is leading the research effort. "Coarse aggregates, such as
crushed rock and gravel, make up most of a given concrete volume. The mining, processing and
transportation operations for these aggregates consume large amounts of energy and adversely
affect the ecology of forested areas and riverbeds."
"Through my research, I want to contribute to efforts towards reducing these demands on our
natural environment by reducing the need for natural coarse aggregates," Kurama said. "
Especially in the years to come, the renovation and replacement of our nation's aging infrastructure
will result in both an increase in the supply of old concrete rubble and the demand for new concrete.
We need to be better prepared to utilize this growing resource at a higher level, which is what my
research is focused on."
The biggest barrier to using recycled concrete has been the variability and uncertainty in the
quality and properties of the recycled material and how this variability affects the strength,
stiffness and durability of reinforced concrete structures. Kurama's team is trying to develop an
understanding of how using recycled concrete affects the behavior of reinforced concrete
structures so that buildings using large amounts of recycled material can be designed for safety
and to serve their intended purpose without undesirable consequences in performance.
Talk about the recycle concrete ,we can from another view to figure that if we use concrete in a
stable standard and render in suitable quantity ,that also can protect environment and save a lot of
money.We can use EZ RENDA plastering machine,make sure the render efficiency don't need to
repair , because EZ RENDA stucco machine have special system-steady hydraulic system.
