ASTM C1708/C1708M-19 PDF Download

ASTM C1708/C1708M-19 is a standard that specifies the test methods used to evaluate the properties of self-leveling mortars containing hydraulic cements. These test methods assess both the freshly mixed properties and the hardened properties of the mortars. The freshly mixed properties include initial flow, flow retention, and healing time, while the hardened properties include compressive strength, setting time, and flexural strength.

It is important to note that these test methods are conducted under standardized conditions for comparative purposes only and should not be considered representative of the performance of the mortars under field conditions.

The standard is applicable for evaluating the performance of self-leveling mortars that are used to improve the levelness, smoothness, and flatness of existing floors. These mortars can be used either as an underlayment to receive floor finishes or as an overlayment to serve as the wear surface. The self-leveling mortars covered by this standard are composed of hydraulic cements, along with fine aggregate, polymers, fillers, and other additives.
