At Terrebonne Concrete, we offer our customers with the industry’s leading ready-mix concrete products. We know that every construction project is unique and may require a different type of concrete. We also know that not all products are created equal and not all concrete solutions are meant for every job.
What is Concrete?
Contrary to popular belief, concrete and cement are not the same thing. Cement is actually just a component of concrete. Concrete is a construction material composed of cement (commonly Portland cement) and other cementitious materials such as Fly Ash and Ground Granulated Blast Furnace Slag Cement, aggregate (generally a coarse aggregate made of gravels or crushed rocks such as limestone or granite, plus a fine aggregate such as sand), water and chemical admixtures.
The word 'concrete' is derived from several sources. Its base origin comes from the Latin word, “concretus”, meaning compact or condensed. The second origin stems from the word,'concresco', which has a two part meaning. “Com” means "to come together" and “cresco” means "to grow."
What is Concrete Used For?
Concrete solidifies and hardens after mixing with water and placement due to a chemical reaction known as hydration. The cement reacts with the water which bonds the other components together, eventually creating a stone -like material. Concrete is used to make pavements, pipes, architectural structures, foundations, roads and bridges, walls and footings, etc. Concrete is one of the most man-made materials used in the world. Concrete powers a U.S. 35 billion dollar industry which employs more than two million people.

Desired Properties of Concrete
Quality concrete should be able to be placed and consolidated in various applications.
Qualities of hardness should always be met with every product. This includes things like resistance to freezing, thawing, water tightness, strength and wear resistance. You should know what you are trying to achieve with concrete and we will ensure that the product meets those expectations.
Quality depends on the material consistency and the water to cement ratio in a product. With this in mind, we believe that water should be minimized as much as possible without sacrificing durability or workability.
The following steps can be used to achieve desired properties:
- Use lowest water to cement ratio as applicable
- The use of Fly Ash and Slag Cement to replace Portland Cement (Enhances concrete's value, therefore reducing customer cost.)
- The use of Chemical Admixtures
- Use the optimum ratio of fine to coarse aggregates
We Use Limestone Aggregate vs. River Gravel
There are many advantages to using crushed limestone over river gravel. First off, crushed limestone has a 5-12% strength advantage in a given amount of cement in the mix. This advantage comes from the fact that cement bonds tighter to limestone than to a slick/smooth gravel, and the strength is derived from the crushed aggregate’s sharp angular faces.
In addition, crushed limestone has a lighter unit weight than gravel, which means it requires about 12% less crushed limestone than gravel to mix a cubic yard of concrete. The crushed limestone concrete is easier to saw through than gravel concrete (most gravel is silica, which is almost impossible to cut with a steel saw.
Limestone also has a lower thermal coefficient of expansion than gravel concrete, which means that slabs poured with limestone concrete will expand and contract less than gravel concrete. Studies have shown that this thermal stability — coupled with limestone’s superior curing properties — results in greater crack spacing and less crack width in limestone slabs.
