Experimental Study on Grouting Effect and Mechanical Properties of the Rockfill Materials Grouted with SCM

Table 1

Sequential numbers of mechanical test groups after grouting reinforcement and the mass percentages of particle size fractions at different gradation levels.

Test no.	Gradation characteristics	Grouted or not	Mass percentage of particle size fractions (%)
			60–40 mm	40–20 mm	20–10 mm	10–5 mm	5–0 mm
1	Average	Not grouted	17.2	39.2	18.6	11.3	13.7
2	Upper bound	Grouted	16.6	35.6	16.4	13.1	18.3
3	Average	Grouted	17.2	39.2	18.6	11.3	13.7
4	Lower bound	Grouted	23.5	48.3	12.8	6.9	8.4
