Twenty-Five Years of Making Concrete
At Atmosphyre, we make our concrete from scratch, buying each material as a single item that goes into our mix. This way we can measure out the exact amount needed for optimal performance. Buying cement powder as a separate material is the only way to know if it is fresh powder or not. After working with concrete for 25 years, we are confident in our tested mix and we are able to sell you products with this confidence.
Concrete and Cooking
Working with concrete is a lot like cooking. You start off with your ingredients and they are mixed together in a certain order to produce a finished product. Much like the final result of cooking is determined by the ingredients you use and how familiar you are with the cooking process, so it is with mixing concrete.
The Importance of Portland Cement
Many people who make concrete sinks to sell today purchase a bagged premixed concrete mix online. The main ingredient that gives concrete its strength is portland cement; however, portland cement has a short shelf life. Fresh cement powder is essential for good concrete. Cement powder hardens when it comes into contact with water or moisture, even while it is in the bag. Cement powder will harden with the moisture in the air in just a few months. Portland cement is also the key ingredient for the strength of concrete. It is also the most expensive ingredient in the mix, so most premixed bag companies are going to use as little as possible in their premixed bags. So when you buy a bag of premixed materials, you not only don’t know how long the cement powder has been exposed to air, you also don’t know how much portland powder is even in your premix bag.
