- "When the adjustment approach on amount of water is used, the normal consistency of
cement paste must be accordant with the consistency obtained when the dropping depth of the
test cone is 28 mm ± 2 mm." is changed into "When the adjustment approach on amount of
water is used, the normal consistency of cement paste must be accordant with the consistency

1Test methods for Water Requirement of Normal Consistency,
Setting Time and Soundness of the Portland Cement
1 Scope
This standard specifies the principle, instruments and equipment, materials, test
conditions and determination methods of test methods for water requirement of normal
consistency, setting time and volume soundness (caused by free calcium oxide) of the
portland cements.
This method is applicable to portland cement and ordinary portland cement, portland slag
cement, portland fly-ash cement, portland pozzolana cement, composite portland cement and
other cements specified to adopt this method.
2 Normative References
The following referenced documents are indispensable for the application of this
document. For dated references, only the edition cited applies. For undated references, the
latest edition of the referenced document (including any amendments) applies.
JC/T 727 Apparatus for determining normal consistency and setting time of cement paste
JC/T 729 Mixer for cement paste
JC/T 955 Boiling box for determining soundness of cement
3 Principle
3.1 Normal consistency of portland cements
Cement paste of normal consistency has a specified resistance to the dropping of a
standard test bar (or test cone). The water required for such a paste shall be determined by
testing the penetrations of pastes with different water contents.
3.2 Setting time
The setting time is the time required for a needle to drop into the cement paste of normal
consistency for a certain depth.
3.3 Soundness
3.3.1 Le Chatelier is used to indicate the volume expansion of cement paste of normal
consistency by determining the relative displacement of two needles boiled in Le Chatelier.
3.3.2 Pat method is used to indicate the volume soundness by observing the overall change
of paste pat of normal consistency.
5humidity shall not be less than 90%.
7 Determination Methods for Water Requirement of Normal
Consistency (Standard Method)
7.1 Preparation Work before Test
7.1.1 The sliding bar of Vicat apparatus can slip freely. Mould and glass base-plate shall be
cleaned with wet cloth, and mould shall be placed on the base-plate.
7.1.2 The pointer shall indicate the Zero when the test bar is adjusted to touch the glass
plate;
7.1.3 The mixer shall operate normally.
7.2 Mixing the cement paste
Use mixer to mix cement paste. clean the agitator kettle and agitator blade with wet cloth,
pour water into the agitator kettle, add 500g cement into water within 5s~ 10s, prevent water
and cement from spilling; place the agitator kettle on the base of agitator, raise it to the
mixing position, start the mixer and mix at low speed for 120s; scrap cement paste on blade
and kettle wall into the kettle, and then mix at high-speed for 120s before stopping.
7.3 Determination procedure of water requirement of normal consistency
Immediately after blending, the cement paste of right amount shall be loaded into the
mould on the glass base-plate at a time; remove the voids in the paste by gently tapping the
slightly overfilled mould five times with a straight-edged knife of about 25 mm in width, and
then slightly incline the straight-edged knife to the mould and gently saw the excessive paste
outward at the point about 1/3 of the upper surface of the mould, and then plaster the top
again from the edge for having a smooth surface. During sawing the excessive paste and
screeding, paste shall not be compacted. Then the mould and base-plate shall be rapidly
moved on to the Vicat apparatus, and the center of the mould shall be located under the test
bar and the test bar shall be lowered to the surface of cement paste. The screw shall be
tightened for 1s ~ 2s, then released suddenly so the test bar may drop into the cement paste
freely and vertically. After the test bar stopped dropping or was released for 30 s, the distance
between the test bar and base-plate shall be recorded. After test bar is raised, the test bar
should be cleaned at once. The whole operation shall be finished within 1.5min after mixing.
The normal consistency of cement paste shall be accordant with the consistency obtained
when the test bar is dropped into the cement paste with the distance 6 mm ± 1 mm from the
base-plate. The quantity of water for mixing is the water requirement of normal consistency
of cement (P). The unit is the percent according to the mass of cement.
8 Determination Method of Setting Time
8.1 Preparation work before test
When the pointer of instrument for measuring setting time is adjusted to touch the glass
6
plate, the pointer shall indicate Zero.
8.2 Preparation of sample
After the cement paste of normal consistency is made according to the water requirement
of normal consistency and 7.2 and loaded in the mould and scraped according to 7.3, it shall
be moved into humidity-maintenance box. The time when the cements are totally added into
the water shall be recorded as the initial setting time.
8.3 Determination of initial setting time ...
