ASTM C - 11 Standard Specification for Liquid Membrane-Forming Compounds for Curing Concrete

White-pigmented membrane-forming compounds serve the additional purpose of reducing the temperature rise in concrete exposed to radiation from the sun. The membrane-forming compounds covered by this specification are suitable for use as curing media for fresh concrete, and may also be used for further curing of concrete after removal of forms or after initial moist curing.

Liquid membrane-forming compound types 1 and 1-D shall be clear or translucent. Type 2 liquid membrane-forming compounds shall consist of finely-divided white pigment and vehicle, ready-mixed for immediate use as is.

Liquid membrane-forming compounds, when tested, shall restrict the loss of water not more than the requirements prescribed. Note 1—This specification addresses only those properties listed in Sections 5 through 8. Membrane-forming compounds with special properties including better water retention, minimum solids content, resistance to ultraviolet radiation, acid and alkali resistance and non-interference with adhesives are described in Specification C Note 2—Solutions of silicate salts are chemically reactive in concrete rather than membrane-forming; therefore, they do not meet the intent of this specification.

The values given in parentheses are provided for informational purposes only. This standard does not purport to address all of the safety concerns, if any, associated with its use.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

These notes and footnotes shall not be considered as requirements of the standard. The allowable composition of products covered by this specification is limited by various local, regional, and national regulations.

Issues related to air quality solvent emission , worker exposure, and other hazards are not addressed here. White-pigmented membrane-forming compounds serve the additional purpose of reducing the temperature rise in concrete exposed to radiation from the sun. The membrane-forming compounds covered by this specification are suitable for use as curing media for fresh concrete, and may also be used for further curing of concrete after removal of forms or after initial moist curing.
