Difference between cement and concrete
Question: What is the difference between cement and concrete?
Answer: One of the most interchanged words in the construction industry is concrete and cement. There is no such thing as a cement driveway or a cement curb; the correct terms are concrete drive way and concrete curb. So what is concrete? Concrete is a mixture of cementitious materials, water, rock and sand. Cement is a powdered ingredient that provides the glue that binds the rock and sand together in a mass called concrete. A concrete mix design is accurately weighed by a computer at the plant, and then the concrete is delivered to the customer in a freshly mixed and unhardened state. The concrete normally sets or hardens within two to twelve hours after it is placed. Concrete needs to cure, and will achieve its maximum strength twenty-eight days after it has been placed. Below are some tips to maintain your concrete surface: • New concrete must be given at least seven (7) days of curing time (at temperatures above 32 degrees) before vehicular traffic is allowed on it. Concrete takes 28 days of curing time to achieve its maximum strength. • Concrete surfaces must be kept as clean as possible. Remove snow and ice as soon as possible. Use sand for traction instead of salt. • Keep lawn fertilizers cleaned off of concrete surfaces. • Apply a quality sealer annually or according to the manufactures directions. Sealer is easy to apply and the most important step to caring for your concrete. • Annual maintenance is important! As you care for your lawn, trees, shrubbery and house, please take the time to care for your concrete pavements. It is a SMALL INVESTMENT for such a GREAT RETURN! • Homeowner warranties covering exterior concrete are extremely rare. Proper care and maintenance is your responsibility. Your concrete surface is like your wood deck or the siding on your house, in that they all must be protected from the environment to reach their expected service life.
