Joseph Aspdin
Joseph Aspdin was a British engineer and inventor who created Portland cement in 1824. By heating limestone and clay together, he produced a durable building material that hardens when mixed with water. This invention revolutionized construction, enabling the development of modern buildings, bridges, and roads. Portland cement is the primary ingredient in concrete, making it one of the most widely used construction materials worldwide. Aspdin’s work laid the foundation for the global cement industry, significantly impacting infrastructure and urban development.
