May 16, 2014· Methods Used For Curing of Concrete There are various methods of curing. The adoption of a particular method will depend upon the nature of work and the climatic conditions. The following methods of curing of concrete are generally adopted. Shading concrete work Covering concrete surfaces with hessian or gunny bags Sprinkling of water Ponding method [.]
Feb 06, 2014· What are additives for concrete that increase initial strength and shorten curing time when the concrete also contains rebar? Use a higher strength mix, like f'c=8,000psi. Use Type III Portland Cement in the mix. This is a finer cement that reacts faster,... Reduce the water/cement ratio. ...
Add the CONCURE SYSTEMS ADMIXTURE to the concrete truck and let drum rotate for 7 minutes before discharge. CURING. CONCURE SYSTEMS recommends following established ACI guidelines for curing interior slabs to receive flooring. Complete installation recommendations are available from the manufacturer. PRECAUTIONS
Accelerators. Accelerators shorten the curing time of concrete, enabling poring in cold weather. Care must be exercised when using accelerators as they can cause an increase in the drying shrinkage of concrete. Calcium chloride is a common accelerator, used to .
Oct 05, 2018· Concrete Curing Blankets. Concrete Blankets are an effective option that cure concrete times faster than a typical insulated blanket and properly maintain moisture throughout the hydrating process. Concrete Blankets are easily transported and installed and maintain ACI compliance for coldweather concreting.
Concrete will cure faster in hotter and dryer conditions. Spray the concrete with the hose. Apply a light spray over the entire surface. Let the water dry and repeat. Spray the concrete repeatedly over a period of several days to slow the curing process. Cover the wet concrete slab with a sheet of plastic.

Ensure the quality of concrete with concrete admixtures. Find admixtures to modify the properties of hardened concrete and ensure quality during mixing, transporting, placing and curing. Find chemical and mineral admixtures that perform variety of functions. Shop set retarders that delay setting or set accelerators that speed up set times.
During the curing process, the concrete should naturally contract slightly, pulling away from the forms and making it easy to pop them off. Using a wooden wedge to help pry the form away from the concrete in order to avoid breaking the concrete edge. 6. Rushing to pour concrete without proper site preparation.
Covering the concrete with impervious paper or plastic sheets. Polyethylene film is an effective moisture barrier for curing concrete and easily applied to complex as well as simple shapes. To minimize discoloration, the film should be kept as flat as possible on the concrete surface. Applying membraneforming curing compounds.
The major reasons for using admixtures are: 1. To reduce the cost of concrete construction 2. To achieve certain properties in concrete more effec tively than by other means 3. To maintain the quality of concrete during the stages of mixing, transporting, placing, and curing in ad verse weather conditions 4.

Concrete is such a hard and durable substance that it's somewhat ironic that it starts out as a liquid mix of cement, aggregate and water. Once concrete is poured, it needs time to solidify and form solid chemical bonds before it can support weight or withstand force.
For more than 40 years, Xypex has been providing Concrete Waterproofing products using Crystallization technologies. Read more about our Concrete Coating Products.
To allow concrete to cure correctly, keep it wet and warm at temperatures between 50 and 90 degrees Fahrenheit for the first week at least. Concrete that does not cure properly can shrink, crack or even develop a dusty, weak and crumbly surface. The longer you allow concrete to cure, the harder it becomes.
