Factors That Affect The Strength Of A Concrete Installation

Posted on: 12 December 2017

Installing concrete is serious work, and it is not something you should do yourself. Even if you want to save money, it is best that you hire a concrete contractor. The reason for this is because certain conditions affect the strength of the concrete's installation. Furthermore, while you can watch videos and do internet searches to get the required knowledge, you still would not have the expertise and experience to get the installation done in a way that you wouldn't have to maintain the concrete again soon. Concrete is expensive so you should probably hire a professional residential concrete contractor to get the job done for you. Listed below are factors that affect the installation:

Raw Materials

High-grade cement is better to use for hydration purposes. Aggregates used need to have a certain consistency in terms of size, shape, grading, and texture to make them more workable and the water used just needs to be drinkable. Believe it or not, cement has a lifespan, and it needs to be stored in a cool, dry place if you want your concrete to be as strong as possible. Cement that was poorly stored can affect the quality of your concrete. Further, silt, clay, and salts in the mixture can reduce its quality.  

Water to Cement Ratio

The water to cement ratio is very important. Too much water can actually ruin a cement mixture. A professional cement contractor would be able to gauge what the right ratio is sometimes just by looking at the paste. A low water to cement ratio is ideal as it increases the strength of the concrete. Too much water dilutes the mixture. If you are doing the installation yourself, you may be tempted just a little to continuously add water to the mixture because water makes it so much easier to mix.

Temperature

Concrete work is best done when it is not too hot or too cold. Some persons would say September and other persons would say that you should not pour concrete in months like January or July unless you are a professional. The temperature needs to be just right. High temperatures strengthen concrete reactions but too low and too dry temperatures can complete stop reactions. Concrete needs both moisture and heat to be strong. Winter is a terrible time because the freeze-thaw reactions tend to deteriorate the concrete and allow cracks that leave room for moisture to penetrate.
