摘要

This chapter begins with a description of Portland cement, a complex material that hardens when wet and which resembles an English seaside rock. The chapter ends with our quest for approaches to reduce the carbon footprint of cement and its more widely used form, concrete. Building structures enabled by the durability of concrete has been an inspiration for architects ancient and modern to create structures that could last forever. The Pantheon, the Empire State Building, and the Burj Khalifa are all grand reflections of a country’s economic importance and ambition.
