1. Water Curing Method
The Water curing method is most general methods of curing as it satisfies all the requirements of curing. These methods maintain the presence of moisture in the concrete during the early hardening period. One of the most common water curing method that is used in the business is the spraying method. Curing by spraying of water is one of the conventional methods of curing concrete in the construction industry. It can be an efficient method for curing by supplying additional moisture during hot weather. By using nozzles or sprayers, water is sprayed on the concrete members, which are to be cured.
2. Membrane Curing of Concrete
Another method of concrete curing is the membrane curing method. Sometimes you pour concrete at a remote place where there might be an acute shortage of water. The large amount of water required for water curing method is not possible for economy reasons too. One type of membrane curing is called the A)wet covering method. In this method water absorbent fabrics are used to maintain moisture on the concrete surface by completely covering the surface immediately after the concrete has hardened sufficiently. They must be continuously kept wet to prevent the fabric from absorbing water from the body of concrete, due to capillary action. Generally jute bags, cotton mats, hussian cloth, etc. are used as a covering.
B)Another type of membrane curing method that can be used is plastic sheeting. The plastic sheet covers the concrete so that it seals the evaporation of water from concrete. A plastic sheet made from polyethylene film is an effective moisture retarder, lightweight and can be used on horizontal and vertical surfaces as well as on the surface of different shapes and sizes.
3. Concrete Curing Compounds
The last type of concrete curing method on the list is the concrete curing compounds. This type of compound form a thin liquid membrane on the concrete surfaces and result in prevention to a certain extent of evaporation losses. Generally, they are available in two types, clear or translucent and white pigmented. The clear or translucent concrete curing compound may contain a fugitive dye to assure complete coverage of the concrete surface by visual inspection. This dye fades as the application is few hours old.
