Why concrete watering curing

Concrete is a water-hardened material, concrete curing is an important process to ensure the quality of concrete construction. In the concrete strength growth period, in order to avoid surface evaporation and other causes of water loss, so that the hydration of concrete is fully carried out to ensure that the strength of concrete, durability and other technical indicators, and at the same time, in order to prevent cracks due to drying, it must be maintained. Traditional concrete curing methods include natural curing (watering), atmospheric steam curing and high temperature and high pressure curing.

Watering is only one of the methods of natural concrete curing. Do a good job of freshly poured concrete curing work, is to ensure the strength of concrete, crack prevention and control of one of the important links. Room temperature concrete within 12 hours after pouring, must be covered with heat preservation and maintenance, ordinary cement not less than 7 days, if you ignore the watering of concrete maintenance, on the one hand, will reduce the strength of the concrete, on the other hand, will make the concrete in the hardening process is too late to replenish the water, and therefore a large number of water shortages and cracks. So do a good job of watering concrete maintenance, both to reduce the temperature of the cracks, but also to reduce the concrete shrinkage and cracks.
