This part replaces DY-94 "Testing procedures for physical and mechanical properties of rocks. 16. Acid resistance and alkali resistance test". This part is related to DY-94 The main technical changes are as follows. --- Added two chapters "terms and definitions" and "principles"; --- Increased stone cutting machine equipment; --- Increased the accuracy requirements of the calculation results; --- Increased phenolphthalein solution; --- Modified the representation of chemical reagents; --- Modified the acid resistance (alkali) test record sheet. This part is proposed by the Ministry of Land and Resources of the People's Republic of China. This part is under the jurisdiction of the National Land Resources Standardization Technical Committee (SAC/TC93). This part was drafted by the Hubei Institute of Geological Experiments, and the Guangdong Material Testing Center participated in the drafting. The main drafters of this section. Yao Qianyuan, Zhao Guifang, Ni Weidong. The previous versions of the standards replaced by this section are. ---DY-86; ---DY-94. Rock physics and mechanics properties test procedures Part 12.

1 Scope
This part of DZ/T 0276 specifies test methods for determining the acidity and alkalinity of rock. This section applies to the rock acid and alkali resistance test in rock physical and mechanical properties test.
2 Terms and definitions
The following terms and definitions apply to this document. 2.1 Acid resistance acidresistance The rock sample is placed in an acidic medium, and the ratio of the remaining mass to the original mass after a certain period of time is expressed as a percentage. 2.2 Alkaliresistance The rock sample is placed in an alkaline medium, and the ratio of the remaining mass to the original mass after a certain period of time is expressed as a percentage.
3 Principle
The rock sample is placed in an acid-base medium. After immersion for a certain period of time, the acidity and alkalinity are calculated and the acid (alkali) solution is soaked. endurance.
