documents, only the versions with the dates indicated are applicable to this document;
for the undated documents, only the latest version (including all the amendments) is

3 Terms and definitions
The following terms and definitions apply to this document.
Reactivity
The reaction rate of lime hydration, which is expressed as the number of milliliters
of 4 mol/L hydrochloric acid consumed in 10 minutes.
4 Activity testing methods
4.1 Principle
Hydrate a certain amount of the specimen. At the same time, use a certain concentration
of hydrochloric acid, to neutralize the calcium hydroxide produced during the lime
hydration process.
4.2 Reagents
4.2.1 Hydrochloric acid (4 mol/L).
4.2.2 Phenolphthalein indicator solution (5 g/L). Weigh 0.5 g of phenolphthalein. Add
50 mL of ethanol to dissolve. Add water to dilute it to 100 mL.
4.3 Test equipment and tools
4.3.1 Jaw crusher 60 mm × 100 mm.
4.3.2 Sampling sieve. 1 mm and 5 mm round hole sieve.
4.3.3 Ground mouth bottle. 500 mL.
4.3.8 Dryer. The diameter is 250 mm.
4.3.9 Beaker. 3000 mL.
4.3.10 Graduated cylinder. 2000 mL.
4.3.11 Burette. 500 mL, minimum scale not larger than 1 mL.
4.3.12 Thermometer. The maximum temperature is 100 °C; the scale is not greater than
1 °C.
4.3.13 Dropper bottle. 50 mL.
4.3.14 Stopwatch (or timer).
4.3.15 Stirrer.
4.3.15.1 The power is not less than 100 W.
4.3.16 Metallurgical lime reactivity automatic detector
4.3.16.1 Timing accuracy. 0.5 s.
4.3.16.2 Liquid level meter measurement accuracy. 0.05%.
4.3.16.3 Titration accuracy. 0.5 mL.
4.3.16.4 pH value detector. 0 ~ 14, resolution 0.01.
4.3.16.5 Mixer speed. 250 r/min ~ 300 r/min.
4.3.16.6 Equipped with constant temperature water outlet.
4.4 Specimen
4.4.1 Specimen size
Follow the provisions of YB/T 042.
4.4.2 Specimen preparation method
Crush the sample, until it passes through a 5 mm sieve. Then use a 1 mm sieve to remove
the fine powder. Mix thoroughly and separate out about 500 g using the sample
reduction method. Store it in a labeled ground-mouth bottle, for later use.
4.5 Test procedures
4.5.2 Automatic hydrochloric acid titration method
4.5.2.1 Turn on the hot water heater. (After the temperature reaches the requirement)
automatically inject 2000 mL of 40 °C ± 1 °C hot water, into the 3000 mL beaker.
4.5.2.2 Start the equipment and the stirring paddle will turn on automatically. The
system enters the test state. The pH value detector detects the pH value. It controls the
pH value to 7.0 ± 0.1.
4.6 Calculation of results
4.6.1 If the results of two independent measurements of the same specimen are not
greater than the allowable difference (see 4.6.2), THEN take the arithmetic mean as the
test result. If the results of two independent measurements are greater than the allowable
difference, increase the number of tests and determine the test results as specified in
Appendix A. The test results are rounded to integers, in accordance with GB/T 8170.
4.6.2 Allowable difference
The absolute value of the difference -- between two independent measurement results
of the same specimen -- shall not be greater than 4% of the average value.
5 Particle size test method
5.1 Key points of method
The specimens are classified for particle size, according to the prescribed sieve mesh
and operating methods. The test results are expressed as the percentage of the quality
of each particle size.
5.2 Test equipment and tools
5.2.1 Square hole sieve. The sieve hole specifications and size deviations comply with
GB/T 6003.The size of the sieve surface is approximately 800 mm × 600 mm; the
height of the sieve frame is approximately 120 mm; handles are installed at both ends
of the sieve frame.
5.3 Specimens
Follow the provisions of YB/T 042.
5.4 Screening steps
5.4.1 The specimen is screened from large holes to small holes. The height of the sieve
from the ground, steel plate or receiving plate shall not exceed 200 mm.
5.4.5 Combine the material above the sieve into the picked lime blocks. Use the same
method for the lime under sieve, to continue to sieve it on the smaller sieve in the
selected series of sieves. The following is same, until the screening is completed.
5.4.6 The screening end point shall be implemented, in accordance with the relevant
provisions of GB/T 2007.7.
5.4.7 Weigh and record the various levels of screened lime products.
5.5 Result calculation
Add up the mass of each level of lime samples. The difference -- between the total mass
and the mass of the original specimen -- shall be within 1.5% of the mass of the original
specimen. Otherwise, the test will be invalid. Loss of lime is calculated at the smallest
level.
5.6 Allowable difference
See Table 1, for allowable differences.
