The evolution of ready-mix concrete is marked by a slow beginning followed by rapid, large-scale adoption. The first recorded delivery occurred in Baltimore in 1913, but the industry's significant expansion didn't begin until the 1960s, establishing it as a cornerstone of modern construction.
Ready-mix concrete's history is not just a story of a product, but of a logistical revolution that transformed construction from a variable, on-site craft into a standardized, highly efficient industrial process.

The Genesis of an Idea: The Early 20th Century
Ready-mix concrete was born from the need to solve a fundamental construction problem: consistency.
The First Delivery
The first known commercial delivery of ready-mixed concrete took place in Baltimore, Maryland, in 1913. This event served as the initial proof-of-concept for a new way of thinking about material supply.
The Problem It Solved
Before this, concrete was mixed on-site. This process was labor-intensive and often resulted in inconsistent quality, with strength varying from one batch to the next. Centralized batching promised a more uniform and reliable product.
From Concept to Industry: Pre-War Growth
The idea slowly gained traction over the next two decades, laying the groundwork for a viable industry.
Initial Commercialization
By 1929, there were over 100 ready-mix plants operating across the United States. This demonstrates that the business model had proven itself on a small but significant scale.
Establishing the Model
This period was crucial for developing the logistics of production and delivery. It established the core components of the industry: the centralized batching plant and the delivery truck, which were far less sophisticated than their modern counterparts.
The Modern Era: The Post-War Boom
The true inflection point for ready-mix concrete arrived in the mid-20th century, driven by unprecedented construction demands.
The 1960s Expansion
The 1960s marked the beginning of a massive expansion for the ready-mix industry. This growth has been continuous ever since.
Drivers of Growth
This boom was fueled by post-war economic prosperity, large-scale infrastructure projects like the interstate highway system, and a surge in urban and suburban construction. Ready-mix was the only practical way to supply the volume and quality of concrete needed for these massive undertakings.
The Significance of This Evolution
The shift to ready-mix was more than a convenience; it fundamentally altered construction project management and structural engineering.
Centralized Quality Control
The primary advantage was moving quality control from the chaotic job site to a controlled factory environment. This allowed for precise measurement of aggregates, cement, and water, leading to predictable strength and performance.
Unprecedented Scale and Speed
Ready-mix enabled a scale and speed of construction that was previously unimaginable. It allowed for continuous pours and ensured that a consistent supply of material was always available, dramatically reducing project timelines.
Understanding the Historical Context
Each milestone represents a distinct phase in the maturation of a critical industry.
- If your focus is on initial innovation: The 1913 delivery in Baltimore is the critical event, representing the shift from concept to reality.
- If your focus is on commercial viability: The growth to over 100 plants by 1929 shows the establishment of a functional business model and the beginning of a true industry.
- If your focus is on market dominance: The 1960s expansion is the key period when ready-mix concrete became the undisputed standard for large-scale construction.
Understanding these stages reveals how a simple idea fundamentally reshaped the way we build the modern world.
