The Qualities of Concrete
In addition to being molded to any shape imaginable, this solid building material offers many advantages:
The Composition of Concrete
Recognized for its great durability and versatility, concrete is composed of two main elements: aggregates and paste (cement). Aggregates generally consist of crushed stone, gravel or sand. By mixing cement, water, and granulate, a chemical reaction occurs and hardens the compound over time.
Depending on the requirements of a project, the type of concrete to be used can vary considerably. Thus, it is possible to add additives to the mixture (admixtures) to modify the physical or chemical properties of the concrete. Under certain conditions, these additives make it possible to substantially improve the quality of the finished product.
Here Are Some of the Concrete Admixtures used by Carrière d’Acton Vale:
DAir entrainers (improves the durability of concrete during a frost period)
Water reducers (reduces the water content of concrete)
Superplasticizers (increases the handling of concrete)
Set retarders (slows the hardening of concrete)
At Carrière d'Acton Vale, we supply premium quality concrete to our clients in Montérégie (Saint-Hyacinthe, Granby), Centre-du-Québec (Drummondville) and Estrie. Whatever your project, you can rest assured that we have the experience and know-how for the job. For more information on the composition of our different concrete products or to get an estimate, get in touch with our specialists who will answer all of your questions with pleasure.
Characteristics of Fresh and Hardened Concrete Required by Garantie Construction Résidentielle
(It is recommended to use abrasives, such as sand and gravel, to replace de-icing salts on concrete.)
|Concrete elements||Class of concrete according to CSA A23.1||Compressive strength at 28 days (Mpa)||E / L ratio||Maximum nominal size of coarse aggregate (c) (mm)||Presence or absence of entrained air|
|Foundation footings||R-1||20(a)||0,70||20||Without entrained air (d)|
|Foundation walls||R-2||20(a)||0,70||20||With entrained air (4-7%)|
|Basement slabs (interior)||R-3||25(a)||0,65||20||Without entrained air|
|Garage slabs (interior and exterior)||C-2||32(b)||0,45||20||With entrained air (5 à 8%)|
|Balconies, stairs and decks||C-2||32(b)||0,45||20||With entrained air (5 à 8%)|
|Outdoor terraces and pool edges||F-1||30(b)||0,50||20||With entrained air (5 à 8%)|
|Walls in insulating formwork||N||25(a)||0,60||14||With or without entrained air|
(a) Values from current practice.
(b) Values from the CSA A23.1-09 standard referred to in the Quebec Construction Code based on the 2010 NBC (reference 7.5).
(c) The maximum nominal particle size of the aggregate is usually 20 mm, but the size can be decreased to allow the use of small diameter pumps and for placement in thin elements.
(d) 3 to 6% air content according to CSA A23.1-09.
