Although concrete is one of the most commonly used building materials on the planet, there are a lot of misconceptions about what it is, what it can do, and how it can be used. In this article, we address 5 of the most common concrete myths.
Myth #1: Concrete is bad for the environment
It’s no secret that the cement industry is one of the world’s primary producers of carbon dioxide and this tends to mean that people believe that concrete is bad for the environment. In reality, concrete is the most durable building material on the market and a properly constructed concrete building can last for hundreds of years. In fact, the majority of greenhouse gases produced by a concrete building over it’s lifetime are produced by the electricity run in the house, rather than the structure itself.
Myth #2: Concrete is impermeable
Even the densest concrete is porous and technically speaking, any substance in a liquid or vapour form is capable of passing through concrete. Despite this, concrete comes in varying degrees of porosity, which varies depending on the mix design, supplementary materials, chemical admixtures as well as the membranes or sealants used to treat the surface of the concrete.
Myth #3: It’s easy to DIY concrete jobs
Whilst it’s true that pre-mix concrete is readily available in hardware stores and there are plenty of DIY tutorials available online, the reality is that it takes a great deal of skill to correctly install concrete. Of course small jobs like cementing in a new washing line, or repairing an existing concrete surface can be easily managed with DIY provided you know what you are doing, larger projects such as driveways, pathways, or any sort of concrete construction should absolutely be left to the processionals.
Myth #4: Concrete is ugly
When most people think about concrete, they immediately imagine the flat, grey type of concrete which is commonly used in construction or civil engineering. However, concrete comes in a variety of finishes and some, like exposed aggregate, can actually be quite beautiful.
Myth #5: Water weakens concrete
Although it’s true that concrete mixed with too much water will inevitably become weaker, concrete actually requires water to strengthen through curing. Concrete curing is not a drying process but one in which water is vaporized. In some cases, curing can take many decades and for this, the concrete needs to be adequately hydrated to avoid weakening and damage.
