Ensuring that the concrete is damp can increase the strength of the concrete during the early stages of curing. It typically takes concrete around four weeks to reach over 90% of its final strength, and the strengthening can continue for up to three years. The process of concrete hardening once it has been placed is called curing, and is a slow process.
Alternatively, in some factory settings, concrete is mixed into dryer forms to manufacture precast concrete products such as concrete walls. Some concretes are even designed to harden more quickly for applications that require rapid set time. Production of concrete is time-sensitive, and the concrete must be placed before it hardens since it is usually prepared as a viscous fluid. It involves mixing water, aggregate, cement, and any desired additives. Proper mixing is essential for the production of strong, uniform concrete. While there are many types of cement, Portland cement is the most commonly used cement, and is an ingredient in concrete, mortar, and plasters.Ĭoncrete can be purchased in multiple forms, including in 60 or 80-pound bags, or delivered in large amounts by specialized concrete mixer trucks. Cement is a substance that is used to bind materials, such as aggregate, by adhering to said materials, then hardening over time.

Purchasing slightly more concrete than the estimated result can reduce the probability of having insufficient concrete. The Concrete Calculator estimates the volume and weight of concrete necessary to cover a given area. Home / other / concrete calculator Concrete Calculator
