Acids, oils, and other liquids pose a challenge to concrete floors, especially if the concrete is exposed to them frequently. Nevertheless, corrosive substances are not the only things that pose a risk to your concrete security. Freezing liquids have the potential to disrupt your concrete floor from the inside out. To better understand how this is possible, let’s first discuss a common component that plays a role in this issue.
The Role of Aggregate in Concrete
After cement is prepared, it needs other ingredients added to become concrete, like aggregate. Aggregate is typically defined as “any object or structure formed from a loosely compacted mass of fragments or particles.” When it comes to concrete, manufacturers typically use gravel or other rock fragments to create aggregate. Modern mixtures often use recycled concrete as an eco-friendly “green” option.
No matter what it consists of, aggregate generally has an absorbent characteristic which helps when water is added to the concrete mix. That absorbency continues even after the concrete is cured. Then, if the concrete is exposed to standing water, the absorbent materials again become saturated.
Introducing the Physics of Expansion
Saturated concrete is in for trouble when freezing temperatures set in. The water within turns to ice and then expands. The result can be aggregate popout, where bits and pieces of the concrete break away from the surface of the concrete, leaving a rough cavity. With continued or repeated exposure to water and freezing, an entire slab of concrete can gradually weaken and lose its smooth surface.
Protect Your Concrete from Water Expansion
The best option for concrete protection is a waterproof barrier. Epoxy coatings from Nevada Custom Coatings seal your concrete to prevent aggregate popout. Epoxy coatings can be temperature adjusted, so that they meet the needs of their environment. This feature of epoxy coatings works very well for freezers and walk-ins where cold temperatures are common.
