A laboratory study of effect of curing on strength, wear and surface hardness of concrete. Curing methods Included Immersion in water, exposure to moist air, or air at 50 percent relative humidity, surface application of proprietary bituminous compounds and other ma-terials. Both compressive and flexural strengths were improved with increase in duration of moist curing. Strengths for several curin proximately the same as f methods tried were ap-or 13 days moist curing. Methods developing the highest concrete strengths also showed greatest improvement in wear resistance and lowest absorption. Specimens showing lowest strengths showed greatest losses in moisture at test.
