MEASURING METHOD OF ADHESIVE POWER BETWEEN ROCK-CONCRETE AND SPECIMEN FOR IT

摘要

PURPOSE: A method for measuring the adhesion between rock and concrete and a specimen therefor are provided to construct a stable structure, and to use the measured data for various building and civil engineering works constructions. CONSTITUTION: A method for measuring the adhesion between rock and concrete comprise the following steps of: processing; completing; fixing; applying shearing force (F); and measuring the shearing force. In the step of processing, the plate-shaped surface of rock is flatly processed. In the step of completing, concrete is cured on the surface of the processed rock, and the specimen is completed. In the step of fixing, the rock part of the specimen is fixed to the measurement device. In the step of applying shearing force, shearing force is applied on the top of the boundary surface of the specimen. In the step of measuring the shearing force, the shearing force is measured when the shear destruction is generated on the boundary surface of specimen by the shearing force.
