From Animal Draft to Digital Automation, The History of Concrete Mixers Reveals How Technology Transformed Construction and Boosted the Growth of Cities
Concrete mixers are present at almost all construction sites. They are essential equipment for mixing stones, sand, and cement in the right proportions. Nowadays, it is hard to imagine a construction site without them. But it wasn’t always this way.
Beginning with Animal Draft
In the past, horses were used to pull concrete mixers. This required effort and a lot of time. Concrete production was limited and inefficient. Everything started to change at the end of the 19th century when the construction of roads and buildings began to require large volumes of concrete.
The first mechanical concrete mixers appeared at that time. They were simple, powered by hand cranks or animal draft. Their capacity was small, but they represented an important step. It was the beginning of the automation of the mixing process.

The Creation of the Motorized Concrete Mixer
The great advancement came in 1916, with Armenian-American engineer Stephen Sepanian. He created the first motorized concrete mixer in history. This invention transformed concrete production, bringing more speed and practicality.
Emergence of the Concrete Mixer Truck
After World War II, in the 1940s, the first concrete mixer truck emerged. A piece of equipment that began to combine transportation and mixing into one system. This model is the basis of what we know today.
Technology Evolution in the 21st Century
Since then, concrete mixers have evolved significantly. Permanently attached to trucks, they have undergone continuous improvements. The goal remains the same: to make the concrete more homogeneous, with speed and efficiency.
In the 21st century, technology has taken concrete mixers to a new level. Automated systems allow precise control of the mixing. There is real-time monitoring and automatic parameter adjustments. With telemetry, it is possible to track performance remotely and improve fleet maintenance.
Changes are also following a sustainable path. More efficient engines, energy recovery systems, and emission reduction are helping with cost savings and environmental respect. This concern is present in new projects and models.
Highlight on SITI in the National Market
In Brazil, SITI is one of the standout manufacturers in this market. With over 30 years of experience, the company invests in cutting-edge technology. Its concrete mixers are made by trained and certified professionals, ensuring greater productivity, performance, and precision.
The focus is on facilitating the work of teams on construction sites. The equipment was created to optimize processes and provide more quality to projects. Over more than 100 years of history, the concrete mixer has established itself as one of the most important inventions in construction.
Today, its evolution continues to drive the growth of cities and the structures around us.
