3 Terms
3.1 Curing compounds for cement concrete
Curing compounds for cement concrete is a kind of emulsion or polymer solution sprayed or painted on the surface of concrete to form a layer of continuous, waterproof and airtight curing film.
3.2 Reference concrete
It refers to the concrete without curing compounds prepared according to the requirements of the test conditions in this standard.
4 General Requirements
4.1 Appearance: uniform, without obvious colour difference and other impurities.
4.2 Consistency: shall meet the requirements of prone to be sprayed (or painted or rolling brushed as required) above 4℃ and form uniform coating.
4.3 Adverse reaction: shall be free from harmful effects on the concrete surface and concrete performance.
4.4 Toxicity: shall be free from any chemical composition harmful to the human body, organisms and environment.
