The process of concrete hardening as soon as it has been put is termed curing, which is a sluggish procedure. It ordinarily requires concrete around 4 months to achieve above 90% of its remaining toughness, plus the strengthening can continue on for up to three decades.

All-intent concrete can generally do The task For numerous DIY tasks and repairs, but take into account other choices such as substantial-power concrete, crack-resistant concrete, and swift-location concrete.
An early case in point at Hoover Dam employed a network of pipes concerning vertical concrete placements to circulate cooling h2o in the course of the curing method to avoid harmful overheating. Identical programs remain employed; according to quantity of the pour, the concrete combine made use of, and ambient air temperature, the cooling method may perhaps final For a lot of months once the concrete is placed. Different here solutions also are used to pre-interesting the concrete blend in mass concrete structures.[126]
