Briefly, it seemed this might become a King Canute moment for Japan when the folly of human hubris was exposed by the power of nature. The carbon footprint of concrete can be lowered by using supplementary cementitious materials (SCMs) such as fly ash, slag cement, and silica fume; by using higher . The arches of the Colosseum are made out of cement, a remarkably strong building material the Romans made with what they had at hand: volcanic ash and volcanic rock. concrete, in construction, structural material consisting of a hard, chemically inert particulate substance, known as aggregate (usually sand and gravel), that is bonded together by cement and water. Pozzolana is derived from one of the primary deposits of volcanic ash used by the Romans at Pozzuoli near Naples. That is why it serves as the foundation of modern life, holding time, nature, the elements and entropy at bay. By Cathy Habas Concrete is a ubiquitous building material that has been in use for thousands of years.
