/> 4. Precautions for the penetration type mortar strength tester:
The penetration instrument should not be kept in the hooked state for a long time, and the working spring should be released as soon as possible.
. Do not empty the bomb or disassemble the penetrometer host at will, so as not to affect the service life and test accuracy.
The digital penetration depth meter should be handled with care, and attention should be paid to protecting the measuring head to prevent it from falling.
The penetrometer should be calibrated at least once a year by the legal metrology department.
5. Calculation of mortar compressive strength:
In the test data, the larger and smaller values of the penetration depth values should be taken, and the remaining penetration depth values should be averaged. .
. According to the calculated average value of component penetration depth and different mortar types, the conversion value of mortar compressive strength can be obtained from the appendix of "Technical Regulations for Testing the Compressive Strength of Masonry Mortar by Penetration Method 1" (). Other types of mortar can be tested according to the requirements in the appendix by establishing a special strength measurement curve. When there is a special strength measurement curve, the calculation of the conversion value of mortar compressive strength should be based on the special strength measurement curve.
The estimated value of the compressive strength of masonry mortar should be determined according to the following regulations: when testing a single component, the estimated value of the component's masonry mortar compressive strength is the converted value of the component's mortar compressive strength. During batch inspection, the estimated compressive strength value of the masonry mortar of this batch of components shall be the minimum value of the average converted value of the mortar compressive strength of components in the same batch or the minimum value of .
