Concrete was not invented at a specific moment. It developed in stages, from ancient building materials used around 6500 BC to modern concrete made with Portland cement in 1824.
The answer to this question is based on how we define concrete. Early methods of creating concrete-like materials are connected with ancient peoples in the Middle East, particularly the Nabataeans and Bedouins, in areas that are now part of Syria and Jordan. In the region, the use of lime-based materials played an important role in the development of early construction techniques. These materials were used in buildings and floors that helped in laying the groundwork for later developments in concrete construction. It is difficult to give credit to a single person or civilization as the inventor of early concrete.
Ancient civilisations, including those in Egypt and China, used concrete-like materials. However, the Romans are particularly known for their extensive use of concrete. Their structures have stood for almost two thousand years, showcasing the strength of their construction methods.
Some of the key developments in the history of concrete and cement involve:
The Nabataeans (in present-day northern Jordan and southern Syria) established primitive construction methods with hydraulic lime. They used this material to construct their houses, floors, and water containers. Hydraulic lime was produced by heating limestone covered with clay, creating a cement-like material that stiffens when in contact with water.
The earliest known concrete floor was discovered in what is now Serbia, which was formerly part of Yugoslavia. This floor was made with a combination of lime, sand and gravel and was almost 25 centimetres thick. It was constructed around 5600 BC, which demonstrates that early civilisations used mineral-based building materials thousands of years ago.
Egyptians used mud and straw to create bricks and binding materials for construction around 3000 BC. At the same time, the earliest Chinese builders were establishing lime-based mortars. Evidence of lime mortar structures was identified near the Yellow River, originating around 2800-2300 BC. After that, lime mortar was also used in parts of the Great Wall of China around 700 BC.
The early Greeks made further developments with volcanic materials with high silica content. The constructors used a naturally formed volcanic material from the volcanic island of Thera, recognised as Santorini, as a pozzolanic component. When this component was mixed with lime and water, it would give a stronger, more resilient mortar appropriate for construction.
The Romans established concrete with lime and volcanic pozzolans that create combinations that toughen even in rainy situations. They further developed construction methods by learning from early Greek constructors. For instance, the Porticus Aemilia in Rome proves the Romans’ capability to use concrete on an extensive scale in a building around 193 BC. This Roman concrete was extensively used in structures like buildings, roads, and baths.
After the decline of the Roman Empire, the methods and knowledge related to Roman concrete were used less in Europe. Several building procedures established by the Romans lost their popularity during the Middle Ages. At that time, European engineers and builders reestablished the method of concrete, testing it with more resilient building materials.
In 1793, a British engineer named John Smeaton found out that limestone mixed with clay created a hydraulic lime when heated. The material hardened in moist environments, which made it especially useful for structures exposed to water. This type of material was used by Smeaton in building Eddystone Lighthouse in Cornwall, which helped prove the capabilities of hydraulic binding materials in advanced construction.
Portland cement was registered by English bricklayer Joseph Aspdin in 1824. He used a blend of finely ground limestone and clay to produce cement by heating. It was called Portland stone due to its visual similarity. Portland cement emerged as one of the most crucial advancements in concrete history and is still the foundational cement used in modern concrete. The main components consist of materials obtained from silica, limestone, and alumina.
In the nineteenth century, reinforced concrete developed as constructors aimed to bypass concrete’s limited resistance to tension. In 1848, French creator Joseph-Louis Lambot constructed and patented reinforced concrete products that involved small boats and water containers by blending cement mortar with iron reinforcement. His trials confirmed that mixing concrete with metal made structures more durable.
In the 1990s, 3D-printing technology created new opportunities for concrete construction. Blends of traditional concrete were not always appropriate for printing, as they can cause equipment blockages and struggle to sustain their shape after being squeezed out. Therefore, investigators and producers started to establish specialised concrete blends tailored to pass through the printing nozzles while sustaining enough stability and load capacity.
Investigators and construction experts expanded research into reusing concrete and other construction materials in the 21st century. Reusing materials from existing concrete can minimise the necessity of producing new ones and possibly reduce carbon emissions. However, examination, transport, processing and preparation can produce emissions.

Concrete remains one of the most commonly used building materials because its properties can be changed to meet the requirements of a wide variety of construction projects and applications.
Concrete works well, especially under compressive forces, enabling it to support massive loads. This makes sure this material is appropriate for floor slabs, foundations, structural components and other load-bearing applications. Steel reinforcement can be used where extra tensile stress resistance is needed.
Fresh concrete can be cast in formwork to produce various shapes, depths, and finishes. It can be used for minor shed foundations, garden paths, as well as for massive industrial slabs.
When the concrete is accurately defined, placed and cured, its load-bearing capacity and resistance to harsh environments are enhanced. However, the longevity of the concrete depends on choosing the accurate mix aligned with the setting instead of expecting a single variant to be universally appropriate for each project.
Concrete does not generate flames when subjected to fire and is considered fireproof. It has thermal properties that resist heat, while the fire resistance of the entire structure will depend on its structural configuration.
When taking into account the initial cost of the concrete, it is crucial to look for its strength, longevity, and low maintenance needs. This makes it a more affordable option in the long term.
The concrete mixtures are primarily intended for exterior settings where the finished surface will be exposed to rain, ice, and fluctuating weather. The right placement, drainage, and curing continue to be crucial, particularly in cold or hot weather.
Modern concrete can be modified for many domestic, commercial and civil engineering applications that include:
Concrete has evolved over thousands of years instead of being invented in a single event. From early lime-based materials used by ancient societies to Portland cement and reinforced concrete used in modern construction, all have contributed to the material used today. Concrete’s strength, adaptability, and durability make it an essential building material, as showcased by Roman structures that lasted for centuries and by its use in modern foundations, roads, floors, and infrastructure. Recent advances such as 3D-printed concrete and concrete reuse are also broadening its applications and helping transform the construction industry.
