Experimental Study on Influence of Connection Defects on Joint Strength of Half-Grouted Sleeve Splicing of Rebar

Table 2

28-day compressive strength measured value of grouting material (unit: MPa).

Hydration ratio (%)	1	2	3	4	5	6	AVG	Standard
12	86.1	89.4	85.8	83.1	87.4	87.5	86.5	≥85

The standard means the demand of grout according to the specification content of JGT 408 [15].
