What You Should Know About Concrete
Concrete is everywhere, from your home’s foundation to the bridge spanning the river to the skyscrapers downtown. Despite its ubiquity, many people know surprisingly little about this essential material. If you’re curious about the concrete basics, explore some fascinating concrete facts and misconceptions to help you understand why this age-old material continues to be so pivotal in construction today.
What is Concrete?
Concrete is a mixture of water, aggregate (such as sand, gravel, or crushed stone), and cement. The cement acts as a binder, holding the aggregate together once it hardens after mixing with water. This mixture results in an incredibly strong and durable material, making it suitable for a range of applications, including buildings, bridges, roads, dams, tunnels, and much more.
How Do You Measure the Strength of Concrete?
Concrete strength is typically measured in pounds per square inch (psi). It is determined by the compressive strength test, where concrete samples are cured under controlled conditions and then compressed until they crack. The strength of concrete depends on the ratio of ingredients, quality of materials, and curing conditions.
Why is Concrete Gray?
The typical gray color of concrete comes from the cement used in its composition. The most common type is Portland cement, which is naturally gray. When mixed with water and aggregates, the resultant slurry retains this gray hue after it hardens.
What is the Difference between Cement and Concrete?
It’s a common misconception that “cement” and “concrete” are interchangeable. Cement is actually just one component of concrete. It acts as the binding agent that, when mixed with water, forms a paste that binds the aggregates to form concrete. Thus, while cement is a raw material, concrete is the final composite product used for construction.
Is Concrete Cracking Normal?
Yes, some degree of cracking is normal and expected. It can occur for several reasons, including shrinkage during the curing process, thermal expansion and contraction over time, and subjecting the concrete to loads that exceed its strength. Proper design and construction practices help minimize and manage these cracks.
Does Concrete Require Maintenance?
While concrete is often touted for its durability and low maintenance, it does require some upkeep to prolong its lifespan and maintain its structural integrity. Regular cleaning, crack sealing, and repairs are essential for maintaining concrete structures.
What is the Biggest Problem with Concrete?
The biggest problem is the challenge of getting the mixture proportions just right and combating less-than-ideal curing conditions. Issues in these areas can reduce durability and strength.
