Architectural Concrete and What You Should Know About It

Architectural concrete combines function and beauty, transforming modern construction. Like traditional concrete, it’s durable but can mimic different textures, colours, and shapes.

This gives architects the freedom to design robust and visually attractive buildings. It’s used for exteriors, interiors, and landscapes, making it a key material in innovative design and architecture.

What is Architectural Concrete?

Architectural concrete is used on visible surfaces for aesthetics and strength. It needs a careful selection of materials to be durable, functional, and visually appealing. Composition, colour, and finish are chosen explicitly for design goals, making them popular with architects for balancing form and function.

Benefits of Architectural Concrete

Architectural concrete offers:

  • Versatility for all structural components.
  • High durability, reducing maintenance costs.
  • Cost-effectiveness with low initial costs and long lifespan.
  • Resistance to mechanical and natural damage.
  • No need for secondary finishes, saving cost and time.
  • Numerous design, colour, and finishing options.

What are the Applications of Architectural Concrete

What are the Applications of Architectural Concrete?

There are many different uses of architectural concrete. Some of the applications of these materials are:

Residential Buildings:

Architectural concrete is an important element for residential construction elements that require a high focus on aesthetic appeal while maintaining the ruggedness of the material. These elements include:

  • Driveways
  • Footpaths
  • Facades
  • Balconies
  • Other internal and external architectural elements

Commercial Buildings:

Architectural concrete is a versatile material for commercial construction and is suitable for malls, concert halls, skyscrapers, and office buildings. It’s used in:

  • Parking garages
  • Flooring (e.g., faux marble, terrazzo)
  • Facades
  • Curved building elements

Transport Infrastructure

Architectural concrete is crucial for transport infrastructure due to its high strength. It’s used in:

  • Highways
  • Retaining walls
  • Footpaths
  • Bridges
  • Tunnels
  • Airports
  • Car parks
  • Street furniture

How to Achieve Architectural Concrete?

Achieving architectural concrete involves a multi-step process that requires careful planning and collaboration from the initial design to the final installation. The following are critical steps in this process:

Understanding the Designer’s Vision Is Vital

Involving all stakeholders early is key to turning designs into structures. Collaboration improves communication, ensuring everyone’s goals are aligned, including designers, architects, and suppliers. The goal is to balance aesthetics with structural integrity to bring visions to life.

Proper Formulation of the Concrete Mix Design

The concrete mix design is critical to the quality of architectural concrete. It requires selecting local aggregates and cement to meet the project’s structural and aesthetic needs.

Surface Finishing

Architectural concrete can be finished in numerous ways to achieve different textures and appearances. The choice of concrete surface finish significantly impact the structure’s visual appeal. Options include:

  • Formed concrete
  • Form-lined concrete
  • Exposed aggregate finishes
  • Trowelled finishes
  • Brushed finishes
  • Dry Shakes
  • Blast-cleaned or mechanically tooled surfaces
  • Patented imprinted concrete
  • Polished concrete

Attention to detail during the finishing stage is paramount, as it enhances the concrete’s aesthetic quality and durability.

Different Formwork of Architectural Concrete

The outcome of architectural concrete heavily relies on the formwork system in use. There are different groups of formwork systems, each serving a unique purpose in the construction process.

Walls Formwork System

Vertical surfaces like walls use two formwork types: panel and girder. Panel formwork is more common for walls. Its unique feature is that panel joints leave impressions on the concrete, adding aesthetic value or design elements.

Infrastructure Construction

Formworks support constructing traffic elements like highways, tunnels, bridges, and walls. They add visual accents to structures. Over time, weather impacts the structure’s appearance, adding character and helping it blend with its surroundings.

Slabs Formwork System

The slab formwork system, derived from wall girder formwork, uses metal or wooden girders. It has a large surface area with few joints, resulting in a smoother finish. This system suits large, uninterrupted flooring or ceiling areas in architectural construction.

Column Formwork System

The formwork system for columns is similar to walls, using either panels or girders based on needs. It enables the construction of columns of different shapes and sizes, ensuring structure and aesthetics.

3D Free Form Surfaces Formwork System

Niche construction projects use unique 3D free-form structures for art and aesthetics. Traditional formworks often don’t fit these unique needs. Formworks are made from a 3D model of the project, enabling unique, custom shapes that go beyond conventional design.

Challenges in Using Architectural Concrete

Challenges in Using Architectural Concrete

Even with all these benefits, architectural concrete can present particular challenges that must be carefully considered and managed throughout the construction process.

Carbon Footprint

The carbon footprint of architectural concrete is a significant issue. Cement production, crucial for concrete, significantly increases global CO2 emissions. Additives and admixtures in concrete can worsen its environmental impact. Since concrete is a top contributor to the construction industry’s carbon footprint, tackling this problem is critical for sustainability.


Compliance with safety codes is crucial for architectural concrete projects. Local and international regulations differ significantly, demanding careful research. Non-compliance risks legal issues and project delays.

Skilled Team Requirement

Architectural concrete success depends on expert teams, including skilled structural engineers and experienced contractors. Hiring and keeping these professionals is challenging but crucial for desired results.

Time-Consuming Processes

Architectural concrete construction is time-consuming. It involves mixing, pouring, and curing. Curing is vital for strength and durability, often taking weeks and affecting project timelines.

Thermal Mass

Architectural concrete has a high thermal mass, which helps stabilise indoor temperatures, but it is poorly insulated. Its low R-value means buildings might only meet energy efficiency standards with extra insulation, impacting comfort and energy costs.

What is Architectural Concrete Today?

In this day and age, these are the primary focal points of architectural concrete:

  • Glass Fibre Reinforced Concrete (GFRC): GFRC contains glass fibres for reinforcement, making it a popular architectural material.
  • Precast Concrete: Precast panels, available in various finishes and shapes, offer a quick, cost-effective option for large projects.


How is architectural concrete made?

Architectural concrete is made by selecting specific cement, aggregates, colour pigments, and admixtures. It starts with choosing the cement type and colour, which affects the concrete’s appearance. Aggregates are selected for colour, texture, and size to meet design needs.

Colour pigments are added for the desired colour, and admixtures improve properties like workability, strength, or curing time.

The mix is created in a controlled environment for consistency and poured into formworks.Form release agents ensure a smooth release, maintaining the concrete’s aesthetic qualities.

What are the materials used in architectural concrete construction?

Architectural concrete construction uses carefully chosen materials for structure and aesthetics. Critical materials include cement for colour and texture, aggregates for surface effects, pigments for colour, and admixtures for performance and durability.

Specialised formwork shapes the concrete, while steel bars and fibres reinforce it. These materials ensure innovative, durable, and appealing architectural concrete projects.

Which type of cement is only used for architectural purposes?

White Portland cement is preferred for its whiter, more consistent colour, ideal for aesthetic projects or when adding vibrant colours to the mix. It offers architects flexibility in design, supporting diverse architectural styles.
