Concrete curing compounds chart
Research has shown the effects of delay in the application of curing compounds to flat slabs and formed vertical surfaces, by measuring the water loss from concrete specimens at various ages. Please contact marketing hanson. Concrete curing techniques fall into two groups - those designed to prevent loss of water, such as the application of impermeable membranes; and those that supply moisture throughout the early stages of the hydration process, such as ponding or the application of wet sand or hessian. Under no circumstances should water be used in periods of cold weather. The curing of structural concrete does not present as many problems as may be experienced in curing thick floor slabs or pavements, because the exposed surfaces are usually smaller. Care should be exercised to prevent large temperature differentials between the concrete mass and curing environment so as to avoid potential cracking due to temperature gradients within the concrete. Early curing of slabs is vital to minimise the risk of plastic shrinkage cracking, especially in climatic conditions combining high temperatures with strong drying winds. This is measured as a percentage of total water retained in the concrete.

The WHITE series of water-based, white-pigmented concrete curing compounds are wax-based dispersions with selected white pigments. When properly applied, WHITE forms a premium-grade membrane, which optimizes water retention. The white pigment reflects the sun’s rays to.

R. MEADOWS is well known for our line of concrete curing compounds that help protect and sustain America's concrete. Curing compounds are used to ensure adequate concrete performance, and is paired with a chart of the standard deviation between the replicate samples.
The use of cold water can be hazardous, especially in hot climates, because of the risk of thermal shock leading to cracking and surface defects.
This is a major concern with surface wear properties on concrete slabs.
The use of spray-applied curing compounds on formed vertical surfaces is difficult and is unlikely to be effective unless the selected grade of compound is applied immediately after the formwork is removed. Spray-applied curing compounds are rated by their manufacturers according to the efficiency with which they provide a barrier to evaporation.

Liquid Membrane-forming Curing Compounds for. Membrane-forming curing compounds are used to retard or reduce evaporation of moisture from concrete.
They can be clear or translucent and white pigmented .
Any such medium must be kept damp constantly during the curing period, for if drying is permitted, the cover itself will absorb moisture from the concrete.
This guide explains what curing of concrete is and gives practical recommendations for its application. The graph shows the effects of air temperature, humidity, concrete temperature, and wind velocity together on the rate of evaporation of water from freshly placed and unprotected concrete.

In dry, windy or arid conditions the formwork may need to be left in place significantly longer, depending on wind speed, air temperature, and relative humidity. Fogging is essentially the same, but the nozzles deliver a finer, mist like spray.
An absorptive medium such as sand, hessian or canvas will hold water on the concrete surface while curing progresses.
