NOT YOUR FATHER'S CONCRETE

Conventional concrete is a simple mixture of water, aggregate, and cement, with additives and admixtures added occasionally for various purposes. From an environmental stand point, concrete is environmentally friendly, but suppliers are finding that they can do more to help protect the environment. This article describes two ways in which the cement production process can be altered to benefit the environment. First, the energy needs for cement production is intensive; burning tires to generate energy disposes of a waste material and conserves fossil fuels. Second, pozzolanic materials, such as fly ash and silica fume, can be added to create blended cements, increasing capacity without adding new kilns. The concrete industry believes that the potential to solve a number of difficult environmental problems are within reach.
