| Significance and Use | ||||||||||||||
| 4. Significance and UseNumerous properties of cementitious
materials are controlled by their initial hydration rate. Examples
include early-age strength development, heat release, and crack
resistance. One direct and convenient measure of this initial
hydration rate is provided by the measurement of the chemical
shrinkage of the cement paste during its hydration. As cement
hydrates, the hydration products occupy less volume than the
initial reacting materials (cement and water). Due to this volume
change, a hydrating cement paste will sorb water from its immediate
surroundings, when available. At early times, this sorption is in
direct proportion to the amount of hydration that has
occurred.1.1 This test method measures the
internal (absolute) volume change of hydraulic cement paste that
results from the hydration of the cementitious materials. This
volume change is known as chemical shrinkage
.
1.1.1 Procedure A, volumetric method. 1.1.2 Procedure B, the density method. 1.2 The values stated in SI units are to be regarded as the 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.
