Concretes are highly regarded as one of the most utilized materials in different construction and infrastructures both in rural and urban areas. It is also the very material that is mostly produced all over the world.
We might think we know everything there is to know about concretes. Most people would say that concretes are strong, hard, and high-performance. However, it depends on several factors. The Richardson concrete works and other companies that specialize in the industry have shared their knowledge with us and we have come up with a list of misconceptions about concrete that we need to reveal to people.
The following are the myths about concrete you need to know:
1.High-strength concrete improves the durability – a durable concrete is what is now needed by most construction projects since it is related to the ability of the concrete material to resist the ingress of carbon dioxide or chloride in the environment. However, stronger concrete does not mean more durable concrete. According to the experts, if one wants to have a durable concrete, it is essential to choose the right type of cement for the kind of environment it would be exposed to and this depends on several factors such as temperature and humidity. The entire choosing process also depends on the mixing, batching, and placing of concrete.
2. A high-performance concrete is equal to high-strength concrete – most engineers think that high strength concrete, which is concrete that has more cement and less water, results in high-performance concrete. A high-performance cement requires several things and not just a high concentration of cement, and it sometimes may not require it at all. It may need low density, high workability, and improved durability. It is true that increasing the amount of cement and its strength, some properties may also improve. However, it is also linked with high cost, higher heat of hydration, and less sustainability.
3. High cement in the mixture means a better product – similar to what e mentioned above, having a higher cement in the concrete mixture does not guarantee durability and quality. The truth is, the opposite would be likely to experience. A concrete with higher cement can result in disadvantage, bad performance concrete, high costs, and unsustainable project materials. When the concrete has a high amount of cement, it becomes more susceptible to cracking and being brittle.
4. You need to stick to a mix-design prescription to have the best results – most engineers think that you need to stick to the mix-design prescription in order for you to have the most durable concrete mix product. However, according to the experts, it is something that needs reevaluation. Better performance is not definitely defined in this. There are things and factors that need to be assessed and taken into consideration. the performance needs to be quantified and qualified.
So, those are the things you need to debunked and forget about concretes. While it is understandable that we often think that concrete has certain qualities, we also need to take into consideration the important things that determine the quality and durability of the concrete and not just mere hearsay.
