Concrete FAQ for West Palm Beach, Florida
What Makes Concrete Crack?
When concrete hardens, it shrinks slightly as excess water is expelled from the mix. To counteract this, control joints are placed at regular intervals to give the concrete some room to fluctuate without too much damage.
How Long Does Concrete Continue to Gain Strength?
The first seven days are considered the most important period of strength gain for concrete. As a general rule, the standard period of time after which concrete strength can be tested is 28 days. What some people fail to realize, however, is that concrete will continue to gain strength for months, as long as moisture is present, allowing the chemical processes to take place.
Why Does Concrete Need to Be Cured?
Curing concrete allows the freshly poured material to reach its maximum strength. In most circumstances, concrete that is cured for seven days can be up to 50 percent stronger than uncured concrete. In addition to developing strength, curing also minimizes the potential for any cracks to form
Is There a Difference Between Cement and Concrete?
Though the two are often confused, cement and concrete are distinct materials. Cement is a binding agent that, when mixed with an aggregate, forms concrete. Essentially, cement is what makes concrete stick together.
How Do You Determine the Strength of Concrete?
The main determinant of concrete’s strength is the water-to-cement ratio. This is measured by pounds of water per pound of cement or gallons of water per bag of cement. In general, the lower the water content, the stronger the concrete.
