Energy and resources efficient concrete

Energy and resources efficient concrete

Further improvements are foreshadowed by introduction of new materials and the application of more energy efficient processes for the manufacture of portland cement. In many locations, recycling of materials recovered from plastic concrete has proved effective, but general recycling of hardened concrete does not appear practical.
