Abstract: In view of strength testing of cementitious grout components, a method based on rebound method for in-situtesting of compressive strength of test block was proposed. The background of preparation of regulations, the framework ofthe regulation, the content of the research, the requirement of the test block making, the test method, selection ofinstruments,the requirement of the strength curve and so on. Through the preliminary test results, the feasibility andnecessity of the research direction were proved. The test not only refined the test block making, the instrument selection,the strength classification method and the test step, but also improved the data processing, the strength curve fitting, theerror statistics and so on, which laid a good foundation for the later preparation of regulations.

Keywords:cementitious grout; rebound method; strength curve
