membrane curing

A process in which either a liquid sealing compound (e.g., bituminous and paraffinic emulsions, coal-tar cutbacks) or a nonliquid protective coating (e.g., sheet plastics) functions as a film to restrict evaporation of mixing water from a fresh concrete surface.

Concrete curing methods can be divided into four categories, namely, water curing, membrane curing, application of heat, and miscellaneous.
The strength and durability were examined under three different curing methods, namely, membrane curing (MBC); moist-air curing (MAC) and water curing (WAC) ponding, by conducting unconfined compressive strength (UCS) tests.
For the membrane curing (MBC) (Figure 1), compacted specimens were cured for 7 days at a relative humidity of 95 to 100 percent and temperature of 22[degrees]C to 25[degrees] C in a curing room.
The values of the UCS for the membrane curing (MBC) for the various cement percentages can be seen to be close to those for the water curing (WAC).
First, any membrane curing compound left on the surface can interfere with coating adhesion.
It also allows for lower material thickness--down to 1/16 inch--and obviates the need for wet or membrane curing.
* What is the cost to remove the laitance layer and membrane curing compound by abrasive blast or high-pressure water cleaning before coating?
