Concrete pavements are the responsible choice for our environment. Unlike petroleum-based products which use up our fossil fuel reserves, concrete is manufactured from three abundant, readily available ingredients: water aggregate and Portland cement. Concrete is built to last decades longer than alternative pavements.
The concrete and cement industries also rely on materials from other industrial processes that are diverted away from landfills. Slag (which comes from the steel industry) can be used to partially replace rocks. Also fly-ash (that comes from the power industry) or ground blast-furnace slag can be used to replace as much asphalt of the cement used in concrete. Even the process of making cement uses recycled materials. High-energy waste, such as scrap tires, can be safely used as fuel for the cement- making process. Each year, a single cement kiln can use 1 million scrap tires, conserving fossil fuels and reducing waste.
As a pavement, it reduces energy costs in many ways. The reflective quality of concrete’s neutral color creates a brighter surface allowing the amount of night light to be reduced. Up to 27% of light falling on a concrete surface will be reflected, compared to as little as 5% of light from asphalt pavements. This saves energy and offers real safety benefits This reflectivity keeps cooler during the day reducing energy costs in adjacent buildings. Concrete is also the smoothest rolling surface, promoting better fuel economy.
In urban areas, concrete also reduces the heat-island effect, a phenomenon associated with dark pavement and roof surfaces that cause temperature increases. The urban heat-island effect can contribute significantly to both energy consumption for air conditioning, and to smog formation.
Newer concrete techniques now allow water to filter through rather than run-off allowing for better storm water and pollution control.
Home and building owners who have built with concrete can lower their heating and cooling bills by 25 percent. Heating, ventilating and air conditioning of concrete structures can be designed with smaller capacity equipment.
Concrete is showing the way for communities to turn gray into Green and is the responsible choice for our workplace, homes and community.

Insulating Concrete Forms (ICFs) provide all the benefits that have made concrete the material of choice for home building worldwide: Solid, lasting construction that resists the ravages of fire, wind, and time.
But ICF’s do plain concrete one better – or rather, two better – by offering two built-in layers of foam insulation. This gives an ICF home some sizable advantages over an ordinary stick-built home. The ICF home provides greater energy efficiency, more peace and quiet, and more day-to-day living comfort.
Building a concrete home with insulating concrete forms (ICFs) saves energy and money. The greater insulation, tighter construction and temperature-moderating mass of the walls conserve heating and cooling energy much better than conventional wood-frame walls. This reduces monthly fuel bills. It also allows use of smaller heating and cooling equipment, saving money in construction.
How much will I save? Houses built with ICF exterior walls require an estimated 44% less energy to heat and 32% less energy to cool than comparable frame houses. A typical 2,000 square foot home in the center of the U.S. will save approximately $200 in heating costs each year and $65 in air conditioning each year.
The energy savings estimates are from a study of 58 single-family houses across the US and Canada. Half had exterior walls constructed with concrete using ICFs made of expanded polystyrene (EPS) or extruded polystyrene (XPS) foam. The other half were neighboring houses with wood-frame walls. All houses were less than 6 years old.


benefits_leed_photo Using concrete can facilitate the process of obtaining LEED® Green Building certification. Leadership in Energy and Environmental Design (LEED) is a point rating system devised by the U.S. Green Building Council (USGBC) to evaluate the environmental performance of a building and encourage market transformation towards sustainable design. The system is credit-based, allowing projects to earn points for environmentally friendly actions taken during the construction and use of a building. LEED was launched in an effort to develop a “consensus-based, market-driven rating system to accelerate the development and implementation of green building practices.” The program is not rigidly structured; not every project must meet identical requirements to qualify.

Three LEED products are currently available:

  • LEED-NC v2.1 for new commercial construction and major renovation projects
  • LEED-EB v1.0 for existing building operations
  • LEED-CI v1.0 for commercial interiors projects

Concrete and LEED
Using concrete can increase the number of points awarded to a building in the LEED system. The following are suggestions for earning LEED-NC v2.1 points through the use of cement and concrete products. The paragraph headings correspond to the credit categories and the credit numbers in the LEED rating system. Points must be documented according to LEED procedures in order to be earned. The USGBC Web site,, contains a downloadable “letter template” that greatly simplifies the documentation requirements for LEED v2.1. The potential available points that can be earned by using concrete range from 11 to 21.


benefits_struct_photo Concrete is one of the oldest and most widely used construction materials and possesses many unique qualities that benefit the owner, developer and designer.

Design Flexibility– concrete can be molded into any shape by using appropriate formwork. This capability can be used to provide tailor-made design solutions to specific problems and also aesthetically pleasing finishes which often eliminate the need for further fixings, e.g. false ceilings.

Specification Variety– concrete can be manufactured to an enormous range of specifications to suit a wide variety of applications. This can be achieved by using different mix designs or by the addition of different materials.

Durability– concrete is one of the most durable materials on earth. Well designed, well placed concrete offers exceptional durability and long life in any structure. Concrete structures built over 100 years ago (even some as long as the Roman times) are still in active service today.

Surface Finish– the aesthetic potential of concrete can be exploited through a variety of finishes. Exposed aggregate, and off-shutter, are two broad categories of decorative surface finishes. These methods, combined with colored aggregates, imagination and various other techniques, form the basis of aesthetic expression in concrete structures.

Sound Insulation – concrete offers protection against noise in densely populated urban situations. Concrete walls and floors are particularly suited to reducing airborne sounds like traffic noise, reducing vibration from plant and equipment, as well as providing insulation against music and conversation.

Thermal Insulation– concrete provides a sustainable, environmentally friendly solution to the growing need to control internal building temperatures. The thermal mass of concrete enables it to absorb, store and later radiate heat created by people, equipment, computers, lighting, appliances and solar gain, resulting in savings in air conditioning.

Fire Resistance– concrete is almost unique in being an inexpensive, readily available building material which is intrinsically fire resistant, needing no additional application of fire protection, and at the same time have structural and aesthetic qualities.
