Concrete is part of the movement
towards more environmentally sustainable built environments. As cities and
urban centers grew throughout the 20th century and environmental impacts of the
built environment became better understood, sustainable building practices have
become a focus of industries and states across the country. Documented by the
U.S. Green Building Council’s LEED Certification, sustainable building
practices include concrete as a major building material. Concrete’s capacity to
recycle materials, its thermal properties, and other characteristics make it a
sustainable choice for many building projects, including concrete contractor projects in Portland.
