The phrase "aggregates grade" is correct and usable in written English.
It can be used in contexts related to construction, engineering, or materials science, where it refers to the quality or classification of aggregates used in concrete or other building materials.
Example: "The aggregates grade must meet the specified standards to ensure the durability of the concrete mix."
Alternatives: "aggregate quality" or "aggregate classification".
ELN was histologically defined as the presence of follicular aggregates grade ≥ 2 with T/B cell segregation and HEV.
Twenty (43.5%) patients had synovial LN (follicular aggregates grade ≥ 2 with T/B cell segregation and HEV).
Thirty out of sixty-three patients (48%%) of the exploratory cohort (Table 1) had synovial ELN defined as the presence of follicular aggregates grade ≥ 2 with T/B cell segregation and HEV.
We also evaluated the presence of lymphoid neogenesis (LN) as defined by the presence of follicular aggregates grade ≥2 (>6 radial B-cells) with T/B cell segregation and high endothelial venules (that is, MECA-79 epitope positive) [ 20].
This could lead to contradictory findings, as is the case with ST TGF-β1 mRNA expression, which was higher in LN-negative patients, but paradoxically, it correlated with B-cell aggregates grade 3 and strongly with the percentage of B cells in ST.

The fine aggregates grading used conforms to the recommended grading of South Africa as contained in Fulton's concrete technology (2009).
Water/cement ratio and aggregates grading are among several variables that influence physical and mechanical behaviour of mortars.
This paper basically focuses on the effect of using different aggregates grading on the properties of SCC.
The influences of the specimen size, aggregates grading, and the existence of bedding surface in RCC on its dynamic properties are investigated.
The principal objective of this survey is to determine an acceptable aggregates grading zone which can be used in production of SCC with ideal properties.
