Portland Cement
Portland cement is a fine powder that, mixed with water and aggregate, hardens into concrete. Its consistent, high-strength hydraulic set made modern concrete construction possible.
Attribution — Built up over time by many contributors, often across different regions.
Joseph Aspdin patented the name 'Portland cement' in 1824, but the modern high-temperature clinker cement was cumulative: Louis Vicat had studied hydraulic limes earlier in France, and Aspdin's son William Aspdin and Isaac Johnson refined the burning process that produced today's cement.
What counts as the invention: The trademarked name (Aspdin, 1824) is distinct from the true clinker cement developed by later refiners.
