Ready-mixed concrete, also known as ready-mix concrete, is an essential material in the construction industry. It is produced in a concrete plant and then delivered directly to the construction site, where it can be used immediately. This method offers numerous advantages, including high quality, consistency, and efficiency. It is the second most used substance on earth after water.

What is ready-mixed concrete?

Ready-mixed concrete consists of a mixture of cement, water, sand, and gravel or other aggregates. The exact composition can vary depending on the specific requirements of the construction project. By producing it centrally in a concrete plant, consistent quality is ensured, meeting stringent norms and standards.

Advantages of ready-mixed concrete

  • High quality and consistency: Central production allows precise control of the mix and quality.
  • Efficiency: Ready-mixed concrete is delivered directly to the construction site and is ready for immediate use, saving time and labour costs.
  • Flexibility: The mix can be tailored to the specific requirements of the construction project.
  • Sustainability: Heidelberg Materials focuses on innovative technologies for CO₂ capture and storage (CCUS) and the development of CO₂-reduced products

History of concrete

Concrete has been used since ancient Rome, where a form known as Opus Caementitium was utilised. This concrete consisted of a mixture of lime, volcanic ash, and water, which provided exceptional durability and strength. Roman concrete was used to construct impressive structures such as the Pantheon and the Colosseum, which still stand today.

Ready-mixed concrete was first used in the 1920s in the USA and has since become established worldwide.
