EMCORIL AC Acrylic Based, Membrane Forming Curing Compound
One constraint in civil construction is the curing of concrete once it has been cast and the formwork is removed. Curing done by conventional methods cannot be ensured to its optimum efficiency when it is done with WATER. The strength and durability of concrete does depend not only upon the correct composition and placing of concrete but also on correct curing. The principle of curing is to prevent the evaporation of the capillary water in the concrete so that sufficient water is available for complete hydration. This leads to better end hydration products and avoids surface dusting and plastic shrinkage.
The conventional methods of curing like water spraying, covering with wet burlaps, polyethylene sheets etc, are not only time consuming but also start after the initial evaporation of water and after the appearance of the first cracks. Ideally curing should begin as soon as possible after the casting of concrete. Emcoril AC is an acrylic emulsion based membrane forming curing compound, to be brushed or sprayed on the fresh concrete only once, at initial stage which is the critical hardening period of concrete or mortar. It forms a seamless film on the surface of the fresh cast concrete and mortars, which arrests the evaporation of water from the capillaries and prevents quick drying of the concrete, thus avoiding the cracks and enabling the concrete to hydrate efficiently.
Emcoril AC should be applied as soon as possible after disappearance of water sheen from the surface. If the concrete is dry, it is recommended to fog down the surface before application of Emcoril AC. Emcoril AC can be applied by brush or by normal knapsack sprayers having suitable nozzle. In case of larger areas motorized continuous spraying devices can be used. The nozzle of the spraying device should be held about 0.7 to 1.0 m distance from the surface and it should be ensured that the complete area is covered. The pump pressure must be maintained throughout the operation to obtain a fine spray.

Advantages of Emcoril-AC:
- Emcoril AC protects green concrete against burning by acute sunrays
- Particularly suitable, where early plastering is required
- Optimum hydration leading to stronger end hydration products
- Does not affect normal setting process of cement
- Minimizes and heals shrinkage / microcracks at early stages of concrete setting
- Ideal for overhead curing, inaccessible places & places having water shortages
- Better solar reflectance lowering the concrete temperature
- No need for removal before application of subsequent surface treatments.
