California-based construction materials specialist Surface Tech is commercializing an alternative supplementary cementitious material (ASCM) whose requisite chemical profile (silicon dioxide + aluminum oxide + iron oxide content > 75 percent) belies binder-optimizing performance potential exceeding that of leading SCM. While fly ash, GGBF slag and silica fume tend toward dosages starting at 10 percent by weight of portland cement, Juno XP has exhibited marked strength development characteristics at 2.5 percent and 5 percent when measured against portland cement controls—particularly at seven- and 28-day cylinder breaks.
