Concrete Curing Compound and Membrane are Helpful in Curing of Concrete

Curing of concrete with the help of plastic sheets or membrane has become efficient and practical way to cure concrete in modern manufacturing and construction industries. Sometimes, people do not remain available with water for curing of concrete or perform the process by following an incorrect process. Incorrect process will result in alteration of finished surface of the concrete product. Moreover, many experts have said that addition of water to concrete surface, which remained unfinished in its setting procedures, can create adverse affects on hydration process by altering different properties of concrete. Therefore, professionals should cover the concrete by using suitable type of plastic material or a Concrete Curing Compound capable of sealing off small pores and retard evaporation of water from surface of concrete.

Common Forms of Membranes to Cure Concrete
Now, let us look over some common types of membranes capable of curing concrete.

Plastic Sheeting
Curing of concrete by the application of plastic sheeting involves covering of different exposed concrete areas in no time without causing any type of damage to concrete finish. However, whenever you use plastic sheeting above different plat surfaces, like for instance slabs and pavements, you should make sure of extending the same beyond slab edges by minimum 2 times of the entire thickness of slab.

Membranes

Some curing compounds are type of chemical products sprayed directly over the surface of concrete and allow its dryness to form impermeable Concrete Curing Membrane. These membranes can easily retard loss of moisture contents from surface of concrete. 

Reasons for Curing of Concrete

Curing concrete has become essential for construction process because of the fact that it allows constant and transitional evaporation of water from entire mixture of concrete. Now, many people ask one common question related to the time, after which concrete proceeds for its curing process. For this, experts related to construction sector have said that concrete curing process depends completely on different environmental conditions, where concrete remained placed, which include placement of concrete directly above the ground, in between different forms, submerged inside the water, directly above the ground and many more. Best practice in this case is the curing of concrete by using concrete curing chemical, which will allow hardening of concrete. Lastly, you should never allow concrete to become dry at any situation and at the same time should maintain curing condition during the starting 24 hours or until the passing of complete setting time of cement.

Concrete Curing Compound Helps in Sealing of Water from Concrete Slabs

Curing compounds are special types of compounds applied to new concrete for sealing the presence of water into it. Application of Curing Compound helps in setting of suitable concrete in relatively less time. Most of the experts related to construction industry prefer to keep concrete slabs in wet condition by traditional sources, including plastic film, burlap and wet straw and many more. Despite, the application of traditional sources help in curing of wet concrete, but such sources never allow using of concrete slabs for a particular period. Here comes the role of different types of curing compounds.

Features of Water-based White Colored Curing Compounds

In the recent few years, water-based white colored curing compounds have witnessed high demand in between different types of manufacturing and construction industries. Concrete Curing Compound of this category is wax-based dispersion available with suitable white pigments or colors. When the professionals apply concrete curing compounds belonging to these categories in proper way, compounds will form membranes of premium-grades, which can optimize retention of water. Furthermore, white pigment of the compound helps in reflecting UV rays of sun and in turn in keeping the surface of concrete in cool condition. In other words, white pigment of the compound plays vital role in prevention of heat formation at excessive amount. Water-based white colored curing compounds incorporate drying time of about two hours, based on different conditions of jobsite. The conditions will include wind, temperature and many more. In addition, the compound is capable to restrict traffic for minimum four hours.

Steps Involved in Application of Water-based White Colored Curing Compounds

Now, let us look over different steps needed for application of this Curing Compound for concrete slab designs. 

Preparatory Steps or Preparation

Professionals involved in manufacturing and construction jobs should make sure of following suitable preparatory steps before proceeding for exact application of compounds. This means, construction personnel should keep application equipment in clean condition and free from all types of materials used in the past.

Re-dispersion Process

Once you complete with the preparatory step, you have to move forward for re-dispersion of all types of separation and settlings present in the container via agitation in gentle way.

Application of Compound

Lastly, you have to spray the compound over an event coat by the help of power sprayer or hand once the water surface disappears from the surface of concrete. Hence, by the application of curing compound in exact way, construction professionals can expect to have strong and dry concrete slab to be used for accomplishment of construction projects.
