Why Are Aggregates Larger Than 5mm Not Recommended for UHPC? Analysis of the Core Reasons
Strict control of aggregate particle size is a key detail in UHPC achieving ultra-high performance. The industry consensus against using aggregates larger than 5mm is rooted in both materials science and engineering practice. Qinglong Group, with 28 years of R&D and production experience in UHPC/GRC/GRG/GRP, has validated the soundness of this rule across hundreds of projects, ensuring consistent quality of ultra-high performance concrete.
