Reinforced Concrete

The use of reinforced concrete is a relatively recent invention, usually attributed to Jean-Louis Lambot in 1848. Joseph Monier, a French gardener, patented a design for reinforced garden tubs in 1868, and later patented reinforced concrete beams and posts for railway and road guardrails.

The first reinforced concrete building constructed in the United States was the Pacific Coast Borax Company's refinery in Alameda, California.

The major developments of reinforced concrete have taken place since the year 1900; and from the late 20th century, engineers have developed sufficient confidence in a new method of reinforcing concrete, called prestressed concrete, to make routine use of it.

What is Concrete?

Concrete is an artificial stone-like material used for various structural purposes. It is made by mixing cement and various aggregates, such as sand, pebbles, gravel, shale, etc., with water and allowing the mixture to harden by hydration.

Quick Facts

  • Concrete is everywhere!!
    Roads, sidewalks, houses, bridges, skyscrapers, pipes, dams, canals, missile silos, and nuclear waste containment.
  • Concrete is strong, inexpensive, plentiful, and easy to make.
  • Concrete is versatile. It can be molded to just about any shape.
  • Concrete is friendly to the environment. It's virtually all natural. It's recyclable. It is the most frequently used material in construction.
  • Slightly more than a ton of concrete is produced every year for each person on the planet, approximately 6 billion tons per year.
  • By weight, one-half to two-thirds of our infrastructures are made of concrete.
  • Cement has been around for at least 12 million years and has played an important role in history (see the section on history of concrete).
