What Is Concrete?
Concrete is a composite material comprising fine and coarse aggregate bonded together with a fluid cement that hardens over time. Most people only see the finished product of a concrete construction, not understanding the intricate process that has taken place to get it there. So, let’s dive into how concrete is made.
The Process of Making Concrete
- Acquiring Raw Materials: The first step involves gathering the necessary materials, primarily sand, gravel, and cement. These components are essential for creating a reliable concrete mix. The Australian Government’s Geoscience Australia website provides ample information about the country’s abundant mineral resources.
- Creating the Mix: Here, the components are blended in specific ratios. The typical ratio, by volume, for standard concrete is 1 part cement, 2 parts sand, and 3 parts gravel. However, this ratio can vary depending on the project.
- Adding Water: Water is then added to the mixture. This step initiates the chemical process known as hydration, where the cement reacts with water to gradually harden and form a rock-like substance.
- Curing: After the concrete is poured into a desired mould, the curing process begins. Curing involves maintaining adequate moisture and a favourable temperature for the concrete to reach its desired strength. According to Cement Concrete & Aggregates Australia, curing can take anywhere from a week to a month.
A Deeper Dive Into Concrete Ingredients
Understanding the creation of concrete isn’t just about knowing the steps. We must also delve into the materials involved, and why each is vital in the process.
Cement: Cement acts as the binder in the concrete mixture, often referred to as Portland cement. Comprising limestone, clay, and iron, cement begins as a powder. Once mixed with water, it undergoes a chemical process called hydration, binding the mix elements together.
Aggregates: These include sand, gravel, and crushed stones. They form the bulk of the concrete mix and provide its structure. The aggregate choice can significantly impact the concrete’s durability, strength, and ability to insulate, making its selection a critical part of the process.
Water: Water activates the cement, and its amount is critical. Too much water can weaken the resulting concrete, while too little will leave it unworkable. Professionals like Skyco Group ensure the right balance for optimal strength and workability.
Innovative Concrete Techniques
Concrete has come a long way from its first known use by the Egyptians around 3000 BC. Innovations in technology have introduced new ways of creating and using concrete.
High-Performance Concrete (HPC): HPC has high durability and strength, making it ideal for structures requiring longevity. The Concrete Institute of Australia offers more insights into the benefits and applications of HPC.
Self-Consolidating Concrete (SCC): Also known as self-compacting concrete, SCC can flow into place under its weight. It’s perfect for areas with heavy reinforcement, and it requires less labour to pour and consolidate.
Green Concrete: This concrete variant is more environmentally friendly than conventional types. It incorporates recycled materials like crushed glass or wood chips as part of its aggregate.
Concrete in Australia
Concrete plays a significant role in the Australian construction industry, with about 30 million cubic meters of pre-mixed concrete produced annually. The use of concrete in various sectors is growing due to its durability, cost-effectiveness, and sustainability. Moreover, the availability of raw materials within Australia contributes to the concrete industry’s growth.
Australia also has stringent quality standards for concrete production. These include Australian Standards AS 1379-2007 for the specification and supply of concrete and AS 3600-2018 for concrete structures.
The Art and Science of Concrete
Creating concrete is both an art and a science. While the basic ingredients remain the same, knowing how to manipulate them for various applications is a skill honed over years of experience. It involves understanding the interplay between elements and knowing how to optimise them for the desired outcome.

Frequently Asked Questions
Why is concrete so important in construction?
Concrete is an incredibly versatile material that provides superior fire resistance compared to wooden construction. It’s also relatively inexpensive and has excellent load-bearing capabilities.
What affects the strength of concrete?
The strength of concrete is influenced by several factors such as the water-cement ratio, the quality of the raw materials used, and the curing process.
What’s the difference between concrete and cement?
Cement is an ingredient used in the production of concrete. Concrete is a mixture of cement, sand, gravel, and water.
What’s the environmental impact of producing concrete?
Concrete production does have an environmental impact, including the emission of greenhouse gases. However, steps are being taken to reduce this impact.
