Concrete

Concrete Milestones
Concrete has been used for many centuries and continues to be one of the most commonly used materials to date. It dates back as early as 7,000 BC when lime-based, hydraulic cements were originally used for concretes. In 1756, John Smeaton presented the concept of “natural” hydraulic cements that was then used to construct the historic Erie Canal in 1818. In fact, natural hydraulic cements were used in US construction throughout most of the early 19th century. Years later, Joseph Aspdin invented the process of making Portland cement in 1824 in which he named the material after the Isle of Portland.

Solid Research

Today, Portland cement has become the most common type of cement used around the world, and the challenge to build pavements or structures with Portland cement concrete to withstand increasing truck loads is ongoing. LTRC has been conducting concrete materials research since its inception and has consistently met that challenge through

a sound construction practice
practical specifications
a surplus of Portland cement concrete materials for research

Over the years, Louisiana Concrete Researchers have provided LADOTD with Portland cement concrete specifications based on knowledge and experience utilizing available materials.

Behind the Research
The foundation for reliable research is a well-equipped and well-staffed laboratory located in heart of LTRC. LTRC has Concrete Cement Reference Lab (CCRL) certification in concrete and aggregates. Two certified technicians, Randy Young and Matt Tircuit, as well as two engineers, Dr. Tyson Rupnow and Patrick Icenogle, manage the concrete materials research within LTRC’s 5,000 square foot laboratory.
