Standard Specifications for Liquid Membrane Forming Curing Compounds and Curing and Sealing Compounds. The most common concrete curing specification in use today. States that the compound must form a membrane and have moisture retention properties equalling 0. ASTM C 3is the most common concrete curing specification in use today because it sets the amount of moisture loss that comes out of concrete during the curing process. ASTM C 3states that the curing compound must form a membrane that has moisture retention properties equaling 0. About ASTM International. Over 18ASTM Standards operate globally.

Defined and set by us, they improve the lives of millions every day. Combined with our innovative business services, they enhance performance and help everyone have confidence in the things the buy and use. Euclid Chemical’s curing and sealing line includes traditional solvent-based products, exempt solvent-based products for VOC-regulated areas, as well as water-base low-odor products for all application environments. This specification covers liquid membrane-forming compounds suitable for application to concrete surfaces to reduce the loss of water during the early-hardening period.

How often should fresh concrete be tested? What is concrete curing compound? The new ASTM specification that deals with curing and sealing compounds.

It does not replace ASTM C-3which covers membrane forming curing compounds. Calipers or Ruler - Measuring the diameter of each cylinder is vital to the test , as you will need to calculate the area of the cylinder to find the strength. Meets ASTM C-3requirement on moisture loss:.

Dry Time: Approximately hrs. SpecTilt 1Premium reactive solvent-based tilt-up bond breaker. A chemically reactive tilt-up bond breaker specially engineered to provide a clean, easy lift of tilt-up. Steel troweled finishes result in a harder, tighter surface that reduces moisture loss, aiding cement hydration. View all product details.

APPLICATION Mixing … For optimum performance, gentle mixing or agitation is recommended. CAUTION: TO AVOID FOAMING, DO NOT MIX EXCESSIVELY. Use WHITE WATER WAX CITY is suitable for use with a wide variety of concrete construction projects. Options include curing compounds and higher performance cure and seal materials.

This test method is under the jurisdiction of ASTM Committee Con quality control of concrete proportioning, mixing, and placing Concrete and Concrete Aggregates and is the direct responsibility of Subcommittee C09. Testing Concrete for Strength. Current edition approved Feb. Originally published as C 39.

Furnish curing compound with a resin consisting of 1percent poly-alpha-methylstyrene and with, by weight, percent or more total solids. Page 1- White pigmented. ASTM C3CURING COMPOUNDS WisDOT Tested and Approved Batches.

Notes: AASHTO M1has been superseded by ASTM C309. All Curing materials carried over the winter must be re-tested prior to use. Find submittal-ready datasheets, SDS, specs, ICC-ES reports.

They can be clear or translucent and white pigmented. White-pigmented compounds are recommended for hot and sunny weather conditions to reflect solar radiation. Curing compounds should be applied immediately after final finishing.
