ASTM C1792 − 14 Standard Test Method for Measurement of Mass Loss versus Time for One-dimensional Drying of Saturated Concretes

ASTM C1792 − 14 Standard Test Method for Measurement of Mass Loss versus Time for One-dimensional Drying of Saturated Concretes

Scope
1.1 This test method determines the mass loss over time due to one-dimensional drying and moisture transport in an initially saturated cylindrical specimen with both ends exposed to constant temperature and relative humidity.

1.2 The values stated in SI units are to be regarded as standard.

No other units of measurement are included in this standard.

1.3 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.

Significance and Use

5.1 Drying behavior is related to the mass transport properties of concrete, such as liquid permeability and water diffusivity.

It depends on a number of factors such as concrete mixture proportions, presence of admixtures and supplementary cementitious materials, composition and physical characteristics of the aggregates and cementitious materials, curing conditions, degree of hydration, and presence of microcracking.

Drying behavior is also affected strongly by the degree of saturation and temperature of the concrete at the start of drying as well as the environmental conditions that exist during drying such as temperature, relative humidity, and air flow rate (wind speed).
