Sustainable concrete is possible
Cement is, of course, a key ingredient of concrete – so an obvious solution would be to reduce the amount of concrete the world needs. But concrete is the second most widely used material after water, and its global annual production is forecast to grow from 14 billion m³ today to 20 billion m³ by mid-century, as human societies urbanize ...

High Density Concretes for Radiation Shielding
An outgrowth of the development of nuclear energy, high-density concrete is gaining wide spread use as a shielding material to provide protection against radiation hazards. In contrast with conventional concrete weighing around 150 pounds per cubic foot, high-density concretes normally weigh from 200 to 250 pounds per cubic foot.

resistance to the ground. When struck, concrete's electrical resistance generates instantaneous and extreme heat that can vaporize moisture in the concrete, causing violently expansive forces that can spall or fracture the concrete. Further, the heat generated during the strike can melt siliceous minerals, creating weaknesses in the concrete.
