~150 BCE: Roman builders widely adopt hydraulic concrete
Roman builders widely used concrete bound with lime and volcanic material. The hydraulic binder hardened in wet conditions, enabling durable foundations, harbors, and large masonry structures without requiring every element to be cut from stone.

The rebuilt Pantheon in Rome was completed under Hadrian with a vast unreinforced concrete dome. Builders varied the aggregates and reduced the dome's thickness toward its crown, demonstrating how cement-bound materials could support ambitious structural forms.

John Smeaton completed the third Eddystone Lighthouse using hydraulic lime mortar selected through experiments. His work connected clay-bearing limestone with the ability to set in water, helping turn binder selection into a systematic engineering practice.

James Parker patented a fast-setting natural cement made by burning clay-rich limestone nodules. Marketed as Roman cement, the material differed from ancient Roman binders and became useful for renders and architectural details during Britain's building expansion.

Louis Vicat developed an artificial hydraulic binder by controlling the mixture of limestone and clay before firing. His experiments reduced dependence on naturally suitable stone deposits and provided a scientific basis for manufacturing cement.

Joseph Aspdin patented a binder made from limestone and clay and named it Portland cement after its resemblance to Portland stone. The product established the name and a manufacturing approach, although later producers developed the hotter-burning process used for modern Portland cement.

Working at Rotherhithe near London, where he had set up after leaving his father's Wakefield firm in 1841, William Aspdin was marketing a stronger cement by 1843. A modified recipe and higher firing temperatures gave a clinker-based product that widened cement's use in concrete, despite needing more fuel and grinding.

Joseph Monier patented cement garden containers reinforced with iron mesh. He later extended the approach to structural applications, contributing to reinforced concrete systems that combined concrete's compressive strength with metal's ability to resist tension.

Frederick Ransome patented a rotating kiln intended to process cement continuously. His own experiments struggled commercially, but the design provided a basis for successful American kilns in the 1890s and the eventual replacement of batch production.

Jules Bied of the Lafarge company patented a cement made from limestone and bauxite while seeking better resistance to sulfates. Calcium aluminate cement developed specialized uses where rapid strength gain or resistance to high temperatures mattered.

Hoover Dam was completed on the Colorado River using concrete placed in blocks with embedded cooling pipes. Controlling the heat released as cement hydrated was essential to constructing the massive structure without excessive cracking.
https://en.wikipedia.org/wiki/Hoover_Dam~1971: Japanese engineers introduce the precalciner
Ishikawajima-Harima Heavy Industries introduced a cement precalciner, moving much of the limestone decomposition into a separate vessel before the rotary kiln. The arrangement increased output from a kiln system and became central to modern dry-process plants.

The main concrete dam at China's Three Gorges project was completed, although generating equipment continued to be installed afterward. The project illustrated the scale of cement demand created by modern infrastructure, alongside major resettlement and environmental effects.

Swiss development funding supported research and industrial testing of limestone calcined clay cement by partners in Switzerland, India, and Cuba. Replacing part of the clinker with calcined clay and limestone offered a route to reduce manufacturing emissions using widely available materials.

Heidelberg Materials inaugurated its Brevik carbon capture and storage facility at its cement plant in Norway in June 2025. Part of Norway's Longship project, with captured carbon dioxide shipped to the Northern Lights storage site, it targets about 400,000 tonnes a year, including emissions released by decomposing limestone.
