Concrete: An Ancient Material Reimagined

Concrete is often thought of as a modern, industrial material. Something associated with architecture, bridges and buildings.

In reality, its story stretches back thousands of years.

Some of the earliest known cement-like materials date to around 6500 BC, when communities in the Middle East discovered that heating limestone could produce a material which, once mixed with water, would harden again into something stone-like. What may have begun as a relatively simple building material would eventually become one of the most important materials in human history. (Nabataea)

From volcanic ash to Roman architecture

It was the Romans who truly began to explore what concrete could become.

Rather than simply using lime and stone, Roman builders mixed lime with volcanic ash known as pozzolana, much of it sourced from the volcanic landscape surrounding Naples.

This seemingly simple addition transformed the material.

The volcanic ash reacted with lime to create a cement capable of hardening in wet conditions and even underwater. It allowed the Romans to construct harbours, aqueducts, enormous vaulted spaces and buildings on a scale that had previously been extremely difficult to achieve. (HISTORY CHANNEL ITALIA)

Perhaps the most famous example is the Pantheon in Rome - Completed almost 1,900 years ago, its vast concrete dome spans approximately 43 metres and remains the largest unreinforced concrete dome in the world.

It is an extraordinary reminder of just how sophisticated this supposedly simple material can be. (DigitalCommons)

 

Concrete doesn’t simply dry.

One of the most fascinating things about concrete is that it doesn’t technically dry in the way paint or clay might. Instead, it undergoes a chemical reaction known as hydration.

When water is introduced to cement, new mineral structures begin to form. These microscopic crystals grow and interlock, binding the aggregates together and gradually turning a pourable mixture into something resembling solid stone.

In other words, concrete is effectively a material that creates itself through chemistry. And unlike many materials, water is not simply something that needs to disappear for the concrete to become strong - it is an essential ingredient in the chemical process that creates that strength.

A material capable of healing itself

Recent research into ancient Roman concrete has revealed something even more remarkable.

Researchers studying Roman building techniques have found evidence that particular lime-rich inclusions within the concrete could react when cracks developed. When water entered those cracks, calcium-rich material could dissolve and recrystallise, helping to seal the damaged area.

In effect, some Roman concrete possessed a primitive form of self-healing behaviour. (Reuters)

It goes some way towards explaining why Roman harbour structures exposed to seawater for nearly two millennia can still be found today. (ASME)

From liquid to stone

For us as furniture makers, perhaps the most captivating quality of concrete is its transformation. It begins almost like a liquid.

It can be poured, coloured, manipulated and encouraged into a mould. Then, over time, chemistry transforms it into stone.

This means concrete occupies a fascinating space between natural and man-made materials. Its fundamental ingredients come from the earth — minerals, sand, stone and water - yet the finished object can be shaped almost without restriction.

Unlike marble, where a form must be carved from an existing block, concrete allows the form itself to be designed first.

Curves, monolithic bases, exaggerated proportions, sculptural profiles and enormous seamless surfaces can all be created because the material takes on the shape of the mould surrounding it.

For a designer, that freedom is incredibly exciting. No two pieces are quite the same. Concrete also refuses to become completely uniform.

Minute differences in pigment, aggregate, temperature, water movement and curing can subtly alter the finished surface.

Small tonal movements, tiny pores and variations within the material become part of its character.

Rather than attempting to replicate the absolute uniformity of a factory-made surface, we embrace those differences. They are evidence that the material has been mixed, poured, finished and polished by hand.

Every piece carries a small record of the process that created it.

 

Ancient material. Modern engineering.

The concrete we use today has also evolved enormously from traditional construction concrete.

Modern high-performance systems such as UHPC (Ultra-High-Performance Concrete) and fibre-reinforced concrete allow designers to create much thinner and more refined sections while maintaining remarkable strength.

At Little London Studio, we use specialist concrete technology developed for decorative and architectural applications rather than conventional building work.

Systems such as Kodiak Pro take the fundamental chemistry of concrete and push it considerably further - using carefully engineered cementitious materials, fibres and admixtures to create concrete with exceptional density, surface quality and strength.

It means a material once predominantly used to build foundations, bridges and fortifications can now be refined into something much more delicate.

Why we work with concrete

There is something appealing about taking one of civilisation’s oldest building materials and using it in an entirely different way.

Concrete has built cities. It has formed Roman temples. It has sat beneath oceans. It has created some of the largest structures ever made.

Yet in the right hands, the same fundamental material can become tactile, refined and surprisingly elegant.

That contrast is precisely what draws us to it.

At Little London Studio, we aren’t trying to disguise concrete or make it imitate another material. We want to explore what concrete itself can become. Through colour, form, texture, polishing and modern material technology, we use it to create furniture that sits somewhere between object, architecture and sculpture.
